Tap to Pay on Android FAQ

View answers to common questions about Tap to Pay on Android.

How do I find the NFC chip location?

On a majority of devices you will find the NFC chip is located towards the centre of the device.

Tip: For the best results when taking a Tap to Pay payment, the card or NFC device should be placed towards the centre of the back of your device. Process a test payment to locate the NFC chip on your device.

Will my personal contactless cards be charged from my mobile wallet if I use Tap to Pay on Android?

No, when Tap to Pay on Android is enabled, it will prevent your device from charging contactless cards in your mobile wallet.

However, if you use a phone case that holds physical cards, we recommend removing them from your phone case to prevent accidentally charging your own card. You can also disable NFC in your Android device settings when you aren’t processing Tap to Pay on Android payments.

To do so:

  • Navigate to your device Settings > Connections > NFC and Contactless Payments.
  • Toggle off NFC to disable.
    • Toggle on NFC to re-enable.

How do I disable Tap to Pay on Android?

Why are the card numbers different when I use Tap to Pay on Android?

You may notice the number on the payment is different from your customer’s physical payment card number. The reason behind this is that when a contactless payment is made (through Apple Pay, Google Pay or Samsung Pay) a tokenised number is generated to serve as an ID for the payment. To clarify, the actual card number isn’t used for the NFC payment itself, but rather this generated payment token.
