A Method To Prevent Your Credit Card Number

I don't know about you....but I am paranoid about giving credit card information over the Internet.

Personally...if there is a 1-800 number to place the order, I will use it rather than type my credit card number in a box on a computer form. This is the best way to avoid "Key Loggers" from grabbing my keystrokes as I enter the number.

However I have heard of another method of foiling "keyloggers" and it sounds good to me.

This is done by adding extra numbers to the credit card number as you type it in

Let us say your credit card number is this

2308324456325

Add 7 numbers (highlighted here but not in reality)

72370783274457673275

The numbers can be different as long as you know where they are

Now after typing them in (which could be captured by a key logging software)...take your mouse and highlight/delete the wrong numbers (key logging software cannot tell which numbers are being deleted!!)

To me this is a great idea...to protect your personal information of any kind.

It's also important to practice good "computer safety" by making sure not to download software that could put keyloggers on your machine (or other malware), or visit sites that would do so, and to regularly check your machine for just such things. (Of course, as Sony's recent rootkit taught us, this isn't quite foolproof either, but it's a reminder that we all need to be more tech savy these days.)

If your that worried, just get one of the credit cards that offer "one use nubmers" where you they issue you a new credit card number for each order. That stops all forms of snopping to steal your number... expect of course the bank itself is still a week point. Personaly I do not worry about it, I have had my card cahrged fraudently a couple times in the past, and every time a single call to my bank fixed it.

Well since we are continuing on the subject of computer safety here is another excellent program that is free

Open Original Shared Link

This is called CrapCleaner. This is an amazing program that really cleans out garbage from your computer system. Somehow it knows the good stuff from the bad and deletes it. I also run Spybot and Adware to kill spyware but 99.9% of the bad stuff is removed by CrapCleaner...plus it removes history logs that are stored and not removed by those other programs. It is also very fast, taking only a few seconds to do its work

I also use Mozilla Firefox for my browser instead of MS Internet Explorer. It is very good for blocking cookies from being installed on your machine...this is also free

Vincent-- that once use number has to be an American thing, it is certainly not in Canada.

Thanks for the advice Lynxear. I use Safari because I primarily use a Mac. I refuse to download any microsoft things onto my computer. The only program on here that is microsoft is word and that is because that is what publishers prefer.

Well, this is pretty much the same thing ya'll are talking about... My mom sent me a list of safety tips for protecting your credit cards a while back: Write "ask for photo id" instead of signing the back of your card. I know someone who has done this. Keep a photocopy of your cards, front and back in a safe in case they are stolen...I don't know my numbers by heart right now anyway. Likewise, write down the 1-800s for reporting a stolen card somewhere you can remember so you can call the number quickly.

Even when you write "ask for ID", they often don't check. (I do this.) But it's better than actually signing it.

BUT, it's not like they actually check the signatures!

I'm "chicken little" when it comes to giving a credit card number over the net. If they will not let me call them with my numbers I don't order from them....I find most don't want to lose a sale so they give in ........

Since I'm in with the baby boomers it could be a age thing for me..... I don't alway buy into everything that comes down the pike...... Again "chicken Little" !!!!!!!!!!!!!

I happen to audit IT systems, and perform security analysis and testing for an audit firm, so I know a bit about this subject!

I think it is just as risky to give your credit card number to someone over the phone. Think about it, your phone conversation can be interecepted! The person on the other end of the phone is typically filling in the same web page that you would!! Further, that person could be logging all credit card numbers, with expiration dates, billing address, etc. and selling those lists to others. Yes it does happen!

In the end your credit card number ends up in the same database no matter how you order it. If the company doesn't have that database and any other interfaces or applications that touch that database adequtely secured....you are exposed to risk!

The best way to avoid this is to get a credit card with a very low limit that still supports your buying trends. Maybe a $250 limit, or $1000 limit, whatever makes sense for your habits. Then only use that card for online purchases. Your risk is limited to $500 no more!!! even that amount can be negotitated down, or eliminated depending on your credit card company.

I used to do that too, until I tried to use my card at the post office, and by law, they are not allowed to take a card that is not signed. I threw a fit, and the nice lady explained to me that with a signature, they can compare to my lisence to make sure that the signature is the same, but that an ID pic can be altered to look like me.(?) So they campare sigs and not pic-id-to-name. She said that I had to sign it, and then add "ID ME" at the end of my signature. Whatever. I just use cash now. Eliminate the whole problem (at least in person, over the internet I use one card that has a fraud protection on it, so I don't worry about someone abusing it).

I agree that the best way to avoid this situation is to avoid situations that would result in spyware and keyloggers. I'm very diligent about computer security and this is what I use:

Spyware Protection

Open Original Shared Link

Open Original Shared Link

AOL Spyware Protection (it stinks, but AOL demanded I accept it :P )

McAfee (came w/ computer)

Virus Protection

McAfee (came w/ computer)

Open Original Shared Link

Firewall

McAfee (once again, 18-month subscription came w/ computer)

You don't need this many, but get a good virus protection, a firewall is a must, and I find you usually should have at least 2 anti-spyware programs to stay completely clean... Spybot and Adaware are the most popular, and since they are free, it doesn't take much to protect yourself. Adaware updates on its own and you can schedule scans, Spybot you have to update, but you can also schedule scans. I haven't had any major issues-- a few tracking cookies that EVERYONE gets no matter what, but even those are few and far between. Provided that you don't download things from random sites or visit shady sites, you shouldn't have any issues with keyloggers, anyway.

You apparantly also have to run the spyware programs when your computer is in safe mode. Otherwise they don't actually work. Someone told me that once and I never would have known.

I hagte to shatter all your dreams here, but compuer security is my current job plus I have worked at one of those 1-800 numbers that you call to place you order, and I have worked in real brick and motar stores. I have also worked directly with credit card fruad, I know most of the tricks. Reality check, NOTHING mention in this thread will stop them. Nothing. Sorry, but thats te facts.

If you have a credit card, you are at risk having it used, and limits wont stop most thieves, there are simple ways to over charge. THere is no realistic way to stop them. You are much better off just dealing with well repsected stores and well respected credit card/debit card banks and not worry about all the "add 7's" and "only use phone calls to order" none of that protects you from anything.

DO run Antivirus, spyware proctection/etc though. DO keep good records as your not liable if you can prove fraud, and DO check your credit report with all major burears at least yearly, if not more often.

I guess this is where it pays to only have one card through a small, local bank that knows you by name and face and shopping habits!

Working with "reputable" institutions doesn't buy you any more security either.

Open Original Shared Link

Data thieves breached the systems of credit-card processor CardSystems Solutions and made off with data on as many as 40 million accounts affecting various credit-card brands, MasterCard International said on Friday.

These people are reputable, and they lost their computer backup tapes!!

In April, investment firm Amertrade announced that backup tapes containing details of nearly 200,000 account holders had been lost in transit. Citigroup and Bank of America lost backup tapes with the data of nearly 3.9 million and 1.2 million account holders, respectively. And data-collection firm Choicepoint gave information on nearly 150,000 U.S. citizens to criminal groups posing as legitimate businesses.

Recently, on Ohio, Alltel made the news as when they were closing a store, they took all the cell phone application forms (With social security numbers, credit card numbers, bank account info, etc.) and threw them in the garbage. Someone found them and broke the story. In a nutshell, this isn't just an "online" or "computer" problem!

It is all about risk management. You cannot eliminate the risk of credit card fraud, unless you simply do not use credit cards. Hmm, can't imagine that! Having a low limit on a credit card brings the risk exposure to a level that you decide you can "risk". If your credit card company allows a purchase beyond the limit that you specifically imposed, how can they hold you liable??

I've never heard of "single use" credit card numbers, sounds like a good idea...

It does, but not much. A "reputable" institutions has more to lose if they screw up, so they are more careful. NO ONE is impremalbe, but there are things they can to do be safer.

As for the one use credit card nubmers, a couple companies are advertising it it. When I still ahd an Amex card they offered it, I usd it a few times worked well. Odvioulsy you can not use it for subscriptions or other reoccuring charges.. In the end I realy do not care. Like I said, I have had my card used, I placed a call, and it was handled. Annoying? Sure... esply if htey max your card out and your stuck needing gas some place, but nothing that causes me any lost sleep. It is just life in the digital age.

Amex is the only company I've seen really advertise the one-time use numbers, but other companies will do the same thing, if you call them and ask to set it up. Gotta be proactive about these things.

Other than the common sense things, check your credit report regularly (you get a free one every year now), and *ALWAYS* check your statement and verify you know what every charge to your account is. (Yes, even the $2.37 charge to the fast food place your husband put on there when he ran out of cash. :-P) Chances are, you'll have to clean up something on your record at some point... no need to stress over it. :-)

I've heard of a couple - at least one was when I called for something else, while I was on hold. Hence, I think calling and asking is the way to go to find out if your credit card company offers it. And, if they don't, you can ask them to! :-)

If your company does not offer them, and enough people call them and ask them to, I'm sure they will start! It will be better for their business!

      Is it common to develop a wheat allergy in addition to Celiac Disease?

      By Stephanie Wakeman · Posted

      Wow, thank you for share Elisal!  We do need to stay focused on the fact we are so much healthier without wheat and gluten as hard as it is! I've learned to love rice and almond flour based sweets and enjoy the corn and plantain chips as my go to salty snacks!

      By ElisaL · Posted

      IDK how common it is but it does happen. I'm celiac, allergic, and intolerant to the fiber in grains. (Fodmaps) So not only do I get sick from cross contamination, also gluten free wheat statch/fiber, and beauty products with wheat will get me. While I don't stop breathing the full body hives and short breath are not fun. Then once I make through that me and the bathroom become reacquaint. Sigh if I didn't feel so much better with the restrictions on my diet I'd feel sorry for myself. Least it makes for some good jokes about how the gremlin that lives in my gut really hates wheat.

      Ocd making gluten fears unmanageable. Need advice

      By Wends · Posted

      Hi Dora77. “Questions I Need Help With” “1. Is it realistically safe to eat food my mom cooks…” YES - you wouldn’t be here if it wasn’t for your mother. Trust she still knows how to take the best care of you in her own way. Mishaps and cross contamination may happen - will happen on occasion, in fact - that’s life. But for the bulk of it as long as you’re aware of cc and try to avoid it for the most part, don’t sweat the small stuff! See the gluten free diet as a process. Own the process, Do Not let the process own you! “2. Do I need to worry about touching doorknobs, fridge handles, light switches, etc. that family members touched after eating gluten? What about public places like bus handles or school desks? Or like if i went to the gym, I would be touching stuff all the time, so there will be small amounts of gluten and those would get transferred on my phone if I touch my phone while in the gym. But I want to knos if it would be enough to do damage.” NO - this is OCD brain at its best! Hijacking your thoughts and justifying it because of the very real fear of gluten contamination. That’s OCD all over. Like a devil in the driving seat. Fears that are based on some kind of reality are hard to argue with. Boss it back! Recognise this for what it is. OCD using fear of gluten as its excuse to keep you entrapped. Own the OCD in this scenario, don’t let it own you. Normal cleanliness rules apply. Washing your hands before you handle food you’re putting in your mouth is fine. Washing after the gym is normal. Once daily cleansing wipe of your phone etc. Even if you did go rubbing your hands all over surfaces and licking them there might be a trace exposure to gluten possible. But I’m guessing you don’t usually do that sort of thing. Even if you inadvertently were to ingest trace gluten - it won’t be enough to do damage, no. It takes weeks to months of at least a few hundred milligrams of gliadin daily for the innate immune system followed by the adaptive immune system in coeliac disease to kick in and start producing antibodies and cause villous atrophy. “3. Is an endoscopy (without biopsy) enough to tell if my intestines are healed? I’d pay privately if it could help and if i dont get a refferal. Or do i need a biopsy?” Only biopsy, as the gold standard of diagnosis, can tell for certain if villi have recovered. Having said that video capsule etc. can give an indication of any inflammation. “4. Could my job (powder coating, sandblasting, etc.) expose me to gluten or damage my intestines through air/dust?” Assuming your employer provides all necessary PPE - appropriate mask and overalls etc. All you can do is take the precautions that are advised according to risk assessments and regulations of the relevant industry governing bodies? (I don’t know what this would be in the USA. Sorry. But there’s safety and governing regs in the UK for this sort of thing. Assuming it would be very similar over the pond in fairness). “5. Do I need certified gluten-free toothpaste, hand soap, shampoo, or moisturizer? (For example: Vaseline and Colgate don’t contain gluten ingredients but say they can’t guarantee it’s gluten-free.)” This comes down to personal threshold of gluten tolerance. People that are highly sensitive may need certified products. Especially those with dermatitis herpetiformis - the skin manifestation of gluten sensitivity. Listen to your body on this one. “6. Is spices like pepper with “may contain traces of gluten” safe if no gluten ingredients are listed? Or does everything need to be labeled gluten-free?” This one is easy - when following a strict gluten free diet, avoid products that say May contain traces of gluten. But it does not have to be labelled gluten free. There are many foods naturally gluten free. Having said that, there is nuance and personal tolerance threshold. If you’re super sensitive “may contain gluten” labelling is a godsend. But this kind of labelling is more aimed at informing customers with type 1 food hypersensitivity/ allergy reactions. The company is basically legally covering themselves, because there may be a risk of cross contamination. Not to be confused that it means there is cross contamination. In addition to products being labelled gluten free. Many products that are labelled can still contain gluten by the way - in fact any processed products labelled gluten free can still contain the allowable level of gluten (up to 20 parts per million according to Codex). A study was done not too long ago that showed gluten free processed products such as cereals, breads, flours etc. can and some are in fact contaminated and have above the legal allowable amount of gluten in them. While most gluten free products are fine for most celiac patients and tolerated, highly sensitive patients fail to heal fully if relying on processed gluten free products. The trace gluten exposure adds up for someone eating a typical western diet of gluten free cereal for breakfast, gluten free sandwich for lunch, gluten free pasta or pizza for dinner for example day after day, week after week. This is why, at least in the beginning after diagnosis, the gluten free diet should be one of whole real food - food that does not require a label. Meats, oily fish, eggs, beans, natural gluten free complex carbohydrates and vegetables according to custom and taste. Limit fruit as fructose worsens leaky gut and has been hypothetically linked to increased OCD and ADHD - Professor Richard Johnson published study on this recently. “7. Is continuing to only eat my own food the better choice, or could I eventually go back to eating what my mom cooks if she’s careful?” NO and YES. What you listed as your current, limited diet is nutrient poor. Correct it as soon as possible for your own sake and future health! Ditto what others have replied regarding vitamin and minerals that are lacking in malabsorption syndromes like celiacs and need replenishing. Gluten free products are not fortified. You were likely healthier, dare I say it, on a gluten containing diet for this reason. Your brain , and gut for healing and maintenance, needs lots of nourishment from omega 3s, B complex vitamins, folate, B12, iron, selenium etc. Meats, fish, natural fats that come with, do not fear - the brain is made of fat. Limit sugar, seed oils, and high glycemic cereals and fruit like bananas unfortunately as they can cause blood sugar highs and lows that can worsen anxiety in some people. Refined carbohydrates should be limited for the same reason. Fructose and simple sugars in excess feed the unhealthy gut bugs that wreak havoc with anxiety disorders like OCD. White potatoes can be problematic for some, also. It can take six weeks of elimination to see improvements. Note, consult your physician regards insulin adjustment if you reduce carbohydrates in the diet. Dr Bernstein diabetes protocol has worked for thousands. Ketogenic and low carbohydrate diets for mental and neurological conditions have shown improvements. Limited studies have and are being conducted under metabolic psychology and nutritional psychology. In a good proportion of anxiety disorders, mental, and neurological conditions including dementias, the brain is lacking nutrition and usable energy, not a drug. Similar in many autoimmune conditions, including celiacs, the prevailing hypothesis is that gut inflammation and resultant permeability allowing exposure to antigens begets triggering the genetically susceptible immune system response. Modern lifestyle exposure, one of the biggest being the food we choose to eat plays a huge role. Avoid ultra processed products, high in seed oils, refined grains, and sugar. Not just gluten can cause a leaky gut. Fructose, alcohol, egg white lysozyme, emulsifiers, added gums, the list goes on. “8. is cutlery from dishwasher safe if there are stains? Stuff like knives is used for cutting gluten bread or fork for noodles etc. I often see stains which i dont know if it’s gluten or something else but our dish washer doesnt seem to make it completely clean.” If in doubt have your own cutlery set, plate and dishes etc. for your sole use that you handwash yourself. Carry a camping fork/spoon set when out and about if needed. “9. I wash my hands multiple times while preparing food. Do i need to do the same when touching my phone. Like if i touch the fridge handle, I wash my hands then touch the phone. I dont eat while using my phone but i leave it on my bed and pillow and my face could come in contact with where it was.” That’s a classic OCD fear. Nothing to do with gluten as such. OCD brain is using gluten as the excuse here. I personally have the habit of using a cleansing wipe or dust cloth on my phone, nightly, that eases this sort of worry. For example a micro fibre dust cloth will do the trick, keep one on your nightstand? They are antibacterial as particles cling to the cloth. “10. Do i need to clean my phone or laptop if theyve been used by people who eat gluten? Even if no crumbs fall onto my keybaord, i mean because of invisible gluten on their fingers.”  NO. But again these OCD thoughts are hard to argue with. If in doubt, just a quick wipe with a cloth daily should suffice. Normal cleanliness practice. But if you don’t, or forget, don’t sweat the small stuff. “11. Does medication/supplements have to be strictly glutenfree? One company said they couldn‘t guarantee if their probiotics don’t contain traces of gluten.” Better if it is gluten free, yes. “12. I had bought supplements in the past, some of them say glutenfree and some of them dont(like the brand „NOW“ from iherb). I bought them and used them when i wasnt washing my hands so often, are they still safe? As I touched and opened them after touching door knobs, water taps etc. It was like a year ago when i bought those and even though i was eating gluten-free, I never worried about what i touch etc.” Still safe if do not explicitly contain gluten grains / derivatives AND if within the use by and use within dates. “I know this post is long. I’m just extremely overwhelmed. I’m trying to protect myself from long-term health damage, but the OCD is destroying my quality of life, and I honestly don’t know what’s a reasonable level of caution anymore.” Really hope these replies to your questions help. Just remember, in the midst of overwhelming thoughts and darkness under OCD clouded vision, the light and sunshine is always shining above. Take a moment or two when you are able in each day - even if it’s last thing at night - to meditate. Focus on something that you enjoy and appreciate. Or sit in a quiet space and try to relax and tune in to your higher self. Ask for guidance and soothing from your guardian angel. Over time it works but don’t worry if your brain is anxious. Eventually it will quieten down some. Try to focus on a real food, nutrient dense and naturally gluten free diet, this will help your anxiety and future health in the long run. Please eat real food - not cornflakes and sandwiches. Eat a steak, eggs or fish for example. Gluten exposures may happen, but don’t sweat it, dust yourself off so to speak, and carry on with a natural gluten free diet as best you can. Own your OCD don’t let it own you! Similarly, when it comes to a gluten free diet for celiac disease, own the process, don’t let it own you! You’re 18. That’s great. I’ve been managing OCD since childhood (in my 40s now. Many years of research, trial and error so to speak. Diet makes a difference. To quote Doc Brown to teenagers Marty and Jennifer, ‘ …your future hasn’t been written yet. No one’s has. It’s whatever you make it. So make it a good one.’

      Gluten free thyroid medications

      By maryannlove · Posted

      Unfortunately not going to be able to let you know how Amneal is working because I still have almost 3 month supply of Mylan.  Had annual appointment with endocrinologist last week (though get scripts for blood work more often) and since was on my last refill, she sent new script to pharmacist.  Staying on my Mylan until it's gone.  (I tend to build up a supply because after trying a couple of endocrinologists for my Hashimotos, one finally got my thyroid regulated by my taking only six days a week instead of adjusting the strength which had me constantly up and down.  Will be forever grateful to her.  Apparently high percentage of folks with Celiac also have Hashimotos so all this relevant/helpful on Celiac.com.
