NFC requires a SMARTPHONE with a CHIP inside of it. You people with iphone 6/s are really on a high horse with this "revolutionary" new payment system. The majority of people in the world don't even have smartphones.
So if shopping someplace where apple pay is accepted makes you people with iphone 6's feel special, go ahead and go shopping there. But it's not going to magically become accepted everywhere just like cash is accepted everywhere.
Cash is never going away.
And yah, your card information may not be stored on the phone, so maybe none of your "money" will get stolen, but people are more likely to steal or mugg someone for an iphone than they would for cash. An iphone 6/6+ is $800-$1,000, if someone steals your wallet, they won't get more than 20 bucks and you can cancel your cards and get the money credited back to you. If someone steals your precious little iphone 6/6+, Apple will not give you a new phone. first of all they can hack it and get any information they want. If you use your phone to make payments, say hello to identity fraud. If you check your online bank website (or if you use an app for banking) then say hello to identity fraud!
