Before you begin
Tap to Pay on Android is currently available with Square Point of Sale, Square Restaurants POS, Square Appointments and Square Invoices. Check out device compatibility to view compatible devices.
Tap to Pay on Android has a per-transaction limit for contactless payments of $25,000, and a per-transaction limit for physical contactless cards of $250. Payments over this limit for physical contactless cards may require verification with a PIN or signature, or decline and prompt for a different payment method.
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 while Tap to Pay on Android is enabled. You can also disable NFC in your Android device settings when you aren’t processing Tap to Pay payments.
Tap to Pay on Android is not compatible with Samsung Galaxy S8, S9 and Note 9. If you’re using Square for Restaurants, Tap to Pay on Android is only compatible with Samsung A32 5G and Samsung A13.

Security practices for Tap to Pay on Android
To ensure payments are processed securely:
Never hand your mobile device over to your customer. Have the customer hold out their card or NFC device, or hand it to you, to tap on your Android device.
As your customer is tapping their card or NFC device, watch for the screen to show the transaction as Approved. This will be accompanied by an audible beep and vibration to confirm that the payment has been accepted.
Review your Transactions to check if a Tap to Pay payment was successfully accepted. Tap to Pay transactions are registered as a Card payment and have the card type and last 4 digits of the card number displayed.
You can remove unused payment types by navigating to ≡ More > Settings > Checkout > Payment.
Enable passcodes on your device. This will require a passcode entry when backing out of the Tap to Pay on Android payment screen. Navigate to ≡ More > Settings > Security and turn the Passcodes toggle on. Then select the option to require the passcode To back out of a customer-facing payment screen.
