I used my GWallet App today 3 out of 4 times and it worked!
The Best Buy and two McDonald's cashiers were pretty impressed with it. They were all "Did you just pay with your phone?"
I tried to go to the Verizon Wireless store to grab an extended battery, but they didn't have the capabilities for "PayPass" or "NFC transactions."
Lastly, I tried to get a pair of touchscreen cold weather gloves from Sports Authority but the store itself was inside a building so I could not get a 3G or a 4G signal. The funds were already in the app but I guess you need to be connected to data to finish the transaction. Lastly, I called GWallet Customer Service and asked them about it and they confirmed that you needed either Wifi/3G/4G for Google Wallet to work.
GWallet is the future. I wish everybody accepted it.
That's good to know... if it wont work without a data connection you have to have a secondary form of payment, you can't rely on it.
I know that for the most part the community is pretty honest, but when it comes to that sensitive of financial data, I would rather get the APK directly from Google, rather than a community. If my debit/credit cards are linked to it, traceability for me is key.
