Can anyone tell me why it’s more secure for me to key in a four-digit PIN – an easy action to crib over my shoulder – rather than to sign my name – an action that requires considerable practice to imitate convincingly?
I’m just asking.
Surely it can’t have anything to do with the little stack of petrol station chits I collect which I appear to have mistakenly signed ‘Abraham Lincoln.’
On the other hand, there is a simplification involved in the payment process, thanks to all of this; we’ve gone from a system nobody remembered to check, to one nobody remembers. Well, do you know all your cards’ PINs?
