Every day I go to my local coffee shop for a morning coffee. I hand them my cup, put my card in the machine and type in a 4 digit number. Done. The person ahead of me had to dig through their pockets to find the right change, then the cashier had to count it and sort it into the till, and then count back the change. Heaven forbid if some little old lady's change purse dumps on the floor.
I'll keep my secure (ish) chip and pin thank you
Why would I want to introduce the complete insecurity of near field silliness?
