How can I activate NFC on my phone?
The process varies depending on the type, model, and operating system of your phone. If you are using Android, go to Settings, Wireless & Network, More, and then NFC. If you are operating a Windows Phone go to App List, Settings, Tap to Share, Tap to pay, and then NFC.
For BlackBerry owners, you need to tap Manage Connections and then NFC. For iPhone users, just click Settings, Control Center, and scroll down. You should see a green button for NFC. Turn it on and you can proceed to cashless payment. More about NFC tags
