The Bank looks after your money, YOU look after the security of your access to it. A 4 digit pin is deemed safe due to the number of chances to 'guess' it against how long it takes to try them all, brute force is going to take far too long to break it. You can't have simple pins like 1234 0000 etc as teh ATMs have a list of what is thought to be too easy.

The problem with signatures is that it relies on the cashier or whoever to check that it matches. AS I POSTED BEFORE pin checking takes that from a human and makes it a logical yes/no. I actually had to sign in "The Works" teh other day, my signature strip is non existant yet she took it without even a blink of an eye. you could have used my card and still got the goods(yes I even know women who used to use their hubbys cards and 'forge' the signature). C&P fixes that.
