Most of the card industry is a security joke.
Even when they're not getting data stolen en-mass, they impliment things like chip and pin which are inherently flawed.
It used to be that a shop would actually touch and look at the card and your signature.
Since chip and pin you don't even hand the card over. You stick it into the slot and punch in the numbers.
This means there is sod all chance of me, a white male, being spotted using the card of "Mrs Jones", "Mr Mohamed" or "Mr Singh". All of which might have been noticed in the past.
