How to use Google Wallet?
I have Google Wallet on my phone, but I’ve never used it. For one, I don’t know where it is accepted. Secondly, what do I actually have to do to use it if I am at a store that accepts it? I know NFC needs to be turned on, but what else do I need to do? Lastly, will it work if I don’t have a data connection, which is sometimes a problem in stores?
