Better than having to carry a bunch of different rewards cards in your wallet.

I did find a lot of difficulty in getting stores to actually either a) scan your phone, they think it's some kind of trick or something, like I'm going to hack the store, thanks unrealistic movie representations of computers or b) actually read the phone, a lot of scanners don't read it at all.

Why they can't just store the rewards info and associate it with my payment method I don't know. Though I guess then they'd have to swipe my debit card on the till as well, most rewards cards scan a barcode of some kind.

Then let me substitute my own barcode that they can scan.
