This How.com.vn teaches you how to use Near Field Communication (NFC) on your Android to share data, read tags, and make in-store payments.

Method 1 of 4:

It's the gear
icon in the app drawer. You may also find it by pulling down the notifications bar from the top of the screen.
It's under the “Wireless & networks” header.
3
Slide the “NFC” switch to the
position. NFC is now enabled.
- This should automatically enable the Android Beam function, as it works in tandem with NFC. To make sure it's on, tap Android Beam, then verify that the switch is in the
  position. If not, slide it on, then tap Yes to confirm.

Method 2 of 4:

Enable NFC on both devices.
You can share anything with someone else who has a NFC-enabled Android, including web links, photos, documents, videos, map directions, and files.
Both screens must be accessible to transmit files via NFC.
4
Press the devices back-to-back. You will hear a confirmation tone once the link is established.
- When beaming content from a phone to a tablet, be sure to press the phone's back right over the part of the tablet where the NFC chip is located.
The content will beam to the other device. When the transfer is complete, you'll hear another confirmation tone.

Method 4 of 4:

Before you can use your NFC-enabled phone or tablet to pay for in-store purchases, make sure you've set up your Android pay account and linked at least one payment method.
If you haven't already turned on NFC, see this method to learn how.
4
Hold the back of the Android to the terminal for a few seconds. This tells Android Pay to send the default payment method info to the terminal. Once a connection is made, a green check mark will appear on the screen.^{[2]XResearch source}
- If you don't see the green checkmark, try holding the phone in a different way. The NFC chip may be located higher or lower on the back of the device. Also try holding the device there a little longer or closer than before.
- If you see a check mark but the cashier gets an error, it may be because the store doesn't accept NFC payments. This could also indicate that your payment method is out of date.
5
Enter your PIN or sign when prompted. This will complete the purchase.
- If your default payment method is a debit card, use the PIN you set up with the bank.
- If you're using a credit card (or making a large purchase with the debit card), use your finger to write your signature on the terminal.
