For fun lets come up with some ideas about how banks could cut card fraud down. Here's mine although I think #1 was an idea someone else mentioned in uk.finance
1) Give all cards an 'alarm' number which when entered at either a cash point or at a C+P terminal will cause the card to be blocked and also send an instruction to the bank to cancel ALL cards (even ones with different banks). This way if someone mugs you, you can just give them your alarm number and all your cards will decline, or better still allow them to use the ATM but give the balance as £0.04.2) In addition to giving people a daily withdrawal limit make their limit also apply for withdrawals made in the last 6 hours (or 24). This will cut down the amount of loss for people mugged at 11:55pm who get the maximum drawn out just before midnight then the same again after midnight. I would have thought that it would be common sense that someone shouldn't be able to withdraw twice their withdrawal limit in the space of 5 minutes!
3) Create card chips that have rotating PINs (eg. changes each time you use the card), e.g. your pins are "1111", "2222" and "3333", when you use it at Asda your PIN is 1111, when you go to the cig ciosk your PIN is now 2222, etc. That way if someone sees you enter your PIN they still won't be able to use it.4) Stop putting CVV numbers on the sig strip and send it in a bit of paper like the PIN is. The CVV number is usually required for online and telephone purchases, if it was as secret as your PIN there would be no risk of fraud. Imagine, without a PIN or a CVV, a credit card would be just a useless bit of plastic. (All my CVVs are scratched off and memorised, just hope noone sees the "VOID" that was printed underneath it)
I know a lot of people have trouble with the C+P system as it is and a lot of my suggestions would obviously be a bad idea for the general public, but I personally and probably most the people in this news group could cope with more confusion so I think these ideas could be made "request only" for people who think they can cope with it it.
