The latest Google Wallet app update has hit the Play Store. Essentially, this brings the Play Store version of the Wallet up up to what Nexus 5 users had, at least feature wise. The version numbers are different. The Nexus 5 has Wallet version 2.0-R137-v13-RELEASE while the new Play Store version is coming as 2.0-R133-v14-RELEASE. Version number specifics aside, Google has also updated the support page with mention of Kit Kat.
Specifically, that page now references Google Wallet Tap & Pay support for “NFC-enabled Android devices running 4.4 (Kit Kat) or higher.” And if not already done, users will need to make sure NFC is turned on by navigating to Settings -> Wireless & networks -> More. Once there just make sure the box to the right of NFC is checked.
Assuming that has been taken care of, launch the Google Wallet app and follow the prompts to get Tap & Pay setup. Otherwise, along with Tap & Pay, Google Wallet also allows users to send money to others using an email address and serves as a place to store all your loyalty cards. This latest update also made mention of minor bug fixes and performance improvements.
The other addition users will see with this update is the ability to request (or check the status of) your physical Wallet card. Google announced the physical Wallet cards yesterday. These cards are able to be used anywhere MasterCard is accepted and will let you spend any balance that you have in Wallet. Essentially, these physical Wallet cards will serve as a prepaid MasterCard.
