(Before It's News)
Google Wallet is gaining a new update that appears to have started rolling out yesterday. The update is offering up quite a bit of new goodies that not only helps make Wallet a little easier to use, but also helps you shop a little smarter on the go.
- Scan the barcode of your Loyalty Cards to add them to your Wallet Account
- New notifications based on your location and loyalty cards to help you “shop and earn rewards.”


At least that is what the
Google Wallet posting on G+ said. However, this function has been available since the last release. (as pictured above). The implementation of it has changed though. Now when you are adding in a Loyalty Card it automatically launches your camera to scan the barcode and you have to tap the wording to add it manually. Images below.

Other than that, near as I can tell, the update just gave a nice new UI slideouts and some adjustments to icon locations.
