Banknotes don't go offline, have server issues, have flat batteries or refuse to accept your fingerprint. Wait and see - when all this ridiculously overcomplicated technology falls flat on it's face, and when every shop has abolished cash payments, you're all going to be stuck with NO way to pay and NO GOODS.
But then again - please go ahead and carry on with your empty "protests" - seeing as you're all "entitled" Americans.
All this "anger" is pathetic, utterly childish and also rather hilarious
PS: I come from the UK, where we've had Chip N PIN for MANY YEARS. I could come to your good country and decry the lack of adoption of THAT... but all I care about is walking in, buying, and leaving - not making a scene over my "rights". LOL
