Credit card signatures: Useless?

SpaceAdmiral writes "Everyone should remember John Hargrave's classic Credit Card Prank on Zug. He tried signing fake names on his credit card receipt, and no one seemed to care. But that's nothing compared to The Credit Card Prank, Part 2. Can he draw obscene pictures instead of signing his credit card? Yes, it turns out. Is there any way of getting your signature checked? . . . Yes, it turns out. But you have to do an awful lot."

  3. Not useless - a "feature" by dsginter · · Score: 3, Informative

    The credit card companies actually advertise this as a feature. Hasn't anyone seen the "Visa Check Card" commercials?

    "Thanks, but I'll have to see some ID."

    That's their sole "feature" - that credit cards are less secure than checks. And the percentage that they siphon from the credit card / direct check transaction goes to cover any fraud.

    So I fail to see how this is an issue. If someone uses my card fruadulently, then I get reimbursed. That is a lot easier than fooling around with checks from a consumer standpoint. From a business standpoint, it is a ripoff because the cost of credit card / direct check transactions *could* be lower.

    In the end, the banks don't even make an effort to catch small scale fraudsters. At one point, I helped a friend do just that but we were displeased to find that the bank and police did not care when we showed them our findings.

    Since the U.S. federal government limits my liability to $50 for someone fraudulently using my credit card, and all of my credit card companies waive even that, I don't care who uses my credit card.

    Not entirely true. If it can be shown that your negligence contributed to the fraudulant usage of your card, you can be held liable. Granted, you have to really be careless for this to ever be an issue.

    For example, loaning it to your friend to make a purchase. He/she makes other purchases on the card, well... you are screwed. The other common occurence is when you do not report a card stolen right away. Then, you can also be held liable.

    I've heard of very few instances of this ever being an issue. But do not take the limited liablility policy to be an excuse to be careless. It can come back to bite you.

    Sure, it's probably too easy to use someone else's credit card without their permission. But remember that the transactions are not settled until long after the swipe (say, a month). Credit cards, evil as they are with their obscene interest rates, do offer substantial protection for consumers and in case of fraud you have recourse without having to pay a cent.

    For example, if someone else purchases something with your card (fraud) you can call up your credit card company and indicate that you did not conduct this transaction, and that the merchant does not have your signature on file. They will check and see, indeed, the signature is not available.

    Another example (a bit off topic but still interesting) is when the Canadian discount airline, Jetsgo, suddenly went bankrupt. They were even selling tickets to passengers the day before they shut down operations. AFAIK, people who bought their plane tickets by credit card had their transactions cancelled because they were not / could not be provided the product or service they paid for. There was no legitimate sale.

    In the US if you have a card linked to your checking account, it can be used as a credit or debit card. As a credit card all that is needed is a signature. A debit card is just a fancy name for an ATM card. When the card is processed as a debit card the machine will ask for your PIN. The problem is in debit mode you can be charged foreign ATM fees (by both your bank and the business processing the card). So it is best to just use the card as a credit card when asked, "credit or debit?" There is also nothing preventing the card from being used one way or the other.

    I work twice a week at a large-chain record store. We've all be instructed, repeatedly, to check for the signatures. As a low-level manager there, I make damn sure the store associates are doing it.

    We won't take a card without a signature on it, or process a transaction for someone whose name doesn't appear on the card (including family). While we check to see if the signature matches, we generally WON'T generally call someone out on a signature that looks different, unless the purchase is unusually large. If we have a suspicion that someone is using a card fraudulently, we notify our managers, who then notify our corporate office and mall security.

    We're not in the business of accusing people without air-tight evidence, because it's bad customer service. Once the appropriate parties have been notified, we and others in our chain keep an eye out for the potential offender and look for more blatant signs of theft or theft of services.

    A lot of people have talked about writing "See ID" on the back of the card for the merchant to check. I've dealt with this before, and if the merchant is following the proper procedures (visa here), they should make you sign the card before they will accept it. The US Postal service will not accept it at all.

    So this should only be a one-off for people who do it, although from my experience and most of the reports here it seems that very few places follow through on this even if they check.

    As for the main question, are the sigs useless? Well no, they're not foolproof but act as a line of defense which makes fraud a bit harder, puts off some people from trying it and maybe gets some fraudsters caught.

They get put in a big box, and every so often, they get thrown away. Visa/Mastercard/Amex/Discover makes no requirements on us to do anything with the signatures. The only reason that we could possibly need a signed receipt is if a transaction is fraudulent, and somebody needs proof that they did NOT sign the receipt. And honestly, that's just a guess. Maybe it's buried somewhere in the 100 pages of fine print, but I've never seen it.

    2. Neither myself or any of my employees are handwriting experts. Somebody could forge a signature very easily. It ain't rocket science.

    Really, all the signatures for are to provide a sense of security to the tin-foil hat types.

  19. Useless on a bearer instrument by SavoWood · · Score: 5, Informative

    For those of you who are afriad of someone stealing your card and making unauthorized purchases, you can rest easy. The credit card companies have been able to detect fraud at the time of purchase for quite a while now. Ever since they felt comfortable enough to offer everyone "zero liability".

    First off, the cashier at your local WalMart isn't a handwriting and signature analysis expert or an identity expert. They aren't expected to be. The credit card companies realized this a long time ago. Strangely enough, if your card is stolen and the clerk compared the signature, the store becomes liable for the fraudulent purchases.

    A Visa or MasterCard is what's called a bearer instrument. It's the same as having cash. If I handed you a $20 bill to pay for something, you wouldn't ask for ID. The same rule applies to Visa and MasterCard. They're all three bearer instruments.

    On the other hand, AMEX is an owner instrument. Only the owner of the card is allowed to use it. IIRC, Diners' Club is the same way. You must be the owner of the card. If you have an AMEX, and your spouse is on the same account, you will each have your own card with your own name on it, and IIRC a different number assigned to the same account.

    Using an owner instrument is a little more tricky. In that case, the cashier should make a cursory check to see if the signatures match, and may ask for ID, however, much more than that is placing liability back on the store instead of the Loss Prevention department of the bank or credit card company.

    A few years ago, I was sitting at home and got a call from Nike Online. Within about 10-15 seconds of that call, I had a call from Visa Loss Prevention on call waiting. Someone had stolen my Visa number and attempted to use it to buy a lot of Nike stuff from the online store. Both Nike and Visa caught the fraudulent purchase at the time of sale. They were able to get in touch with me, the local police department, and set up a sting to get the thief. I wasn't charged anything, and had only a minor problem while I waited for my new card to arrive since they had to kill the old number (which sucked as I had just memorized it and the code on the back).

    Checking IDs is just as bad as airline security. It does nothing to actually prevent crime. It just gives the underinformed a (false) sense of security.
