Google recently indicated that devices running Android 4.3 and older will not be allowed to make tap-and-go payments via Google Wallet.
The change goes into effect April 14. Moving forward, Android devices will need to run Android 4.4 KitKat and up to make NFC-based mobile payments. Additionally, Google said mobile payments will no longer be possible from the Samsung Galaxy Note III, HTC Evo 4G LTE, and the Google Nexus 7 (2012).
Google did not provide a reason for making the change.
