You can't buy things with a fingerprint Apple Pay-style, but Google Wallet for iOS has been updated to support Touch ID. Instead of entering a PIN to open Google's mobile wallet app, you can now choose to authenticate with the touch of a finger. It's a slightly faster way into Wallet, where you can send money, request payments, and access loyalty programs like always. Google has also added the ability to split a charge between multiple people, perhaps hoping it can build some momentum against Venmo, Square Cash, and other apps that have proven popular when the lunch bill shows up. Aside from these changes, Google Wallet is now optimized for iPhone 6 and 6 Plus and has added some additional Material Design flourishes across the app. Many iPhone 6 owners will probably stick with Apple Pay, but it's good to see that Google is still putting resources into Wallet on iOS for the loyal customers that keep using it.
