How to Tap and Pay with Google Wallet in Android 4.4 KitKat

Google Wallet’s NFC payment technology has long been limited to certain devices on certain carriers which allowed it. With Android 4.4 KitKat, Google introduced a new, open architecture for NFC payments that opens the service to any mobile carrier.

Now, users with an NFC-enabled smartphone can use Google Wallet or other apps that have enabled the new NFC Host Card Emulation technology to make payments at over a million retailers that accept NFC payments. Here’s how to set up the service with Google Wallet on the Nexus 5.

1. Sign into Google Wallet. The Google Wallet app is preinstalled on the Nexus 5, or can be downloaded from Google Play on other devices. 

2. Tap "Set up Tap and Pay" in the appropriate card on the My Wallet screen.
