"We don't use watches anymore (check your smartphone), we still pay with our wallet and with cash."

When I was living in the UK about 70% of my purchases were done with a chip and pin card, even a couple of beers at a pub.

This because in the end it was quicker and easier than using cash.

If NFC makes paying quicker and easier than using cash or cards, the demand will be there: by the end of the month there will be millions of iPhone6 customers waiting to test these new features.

If I were a shop/chain owner, I would be scrambling to try to please them, before the competition does.
