Troubleshooting the Tap to Pay app (Android)

Easily fix common errors in the Android Tap to Pay app with our step-by-step troubleshooting guide.

1. Reader Error – NFC Disabled (iOS)

If you see the error “Reader Error – NFC Disabled”, it usually means that NFC is turned off on your device. To resolve this, you can enable your NFC reader in your device settings.

  • Open the Settings app.
  • Go to Connected Devices → Connection Preferences → NFC. (On some devices, it may also be under Settings → Connections → More Settings.)
  • Turn NFC on.
  • Restart Your Device ( Some devices require a restart for NFC to work properly after enabling it.)

Once NFC is enabled, your reader (which is needed to tap and read cards) should connect, and the app will function as expected.

 

2. Unable to move past the Contribution Step of the Checkout Page

If you can’t proceed past selecting a contribution amount, the issue may be caused by your iPhone’s accessibility settings. Enlarged text or display adjustments can alter the page layout, which may cause buttons like Other or Continue to be hidden.

Here's what that might look like:

To resolve this, you’ll need to reset certain text and display size settings on your device that may be affecting the app’s layout.

1. Font Size

  • Go to Settings → Accessibility → Text and display (or Display → Font size on some devices).
  • Make sure the Font Size is set to default, not medium or large. 
2. Display Size / Screen Zoom
  • Go to Settings → Display → Screen zoom or Display size.
  • Ensure it is set to default.
3. Bold Text
  • Go to Settings → Accessibility → Text and display → Bold Text.
  • Make sure Bold Text is turned off.
Once these settings are adjusted, the contribution page should display three suggested percentages, one box labeled Other and a contribute button at the bottom to proceed with your payment
