I have a NAB Qantas AMEX/MC combo and on several occasions I have used my AMEX and entered my PIN but the terminal/receipt indicates that I still need to sign. This is quite annoying because a few retailers have thought something suspicious is going on.
What is worse, there appears to be no pattern to when this occurs. For example, at the same Woolworths petrol outlet, my PIN has worked without issue on several occasions and on other occasions it has requested I sign even after correctly entering my PIN.
Has anyone else encountered this problem?
