The inner workings of Google Wallet

Question

How exactly does Google Wallet work under the hood ? Is there any low level explanation available as a publication or something else ? I am just wondering how is it possible to store the card information to a phone then emit the signal to the pos machine. Thanks.

Answer 1

Your question is really very general...

Basically it communicates via NFC with the POS machine - like your "real credit card" would too...
