However meaning I have to hold a card with me so that the barista can punch it each time I buy some espresso. If the coffee store begins to simply accept Google Wallet -- and if I have a cellphone with NFC capability and the Google Wallet app -- my expertise can keep observe of all the things for me.
I just have to use my phone to make the acquisition and it will register what number of cups I've bought since my final free one.
