Confirm each target device runs Android 13 or later and has a security update from within the past 12 months; devices on earlier Android versions cannot use Tap to Pay.
Add the Terminal Android SDK Tap to Pay artifact to your Gradle dependencies: com.stripe:stripeterminal-taptopay and com.stripe:stripeterminal-core at version 5.0.0 or later.
Use TapToPayDiscoveryConfiguration when calling Terminal.getInstance().discoverReaders() to discover the device as a Tap to Pay reader.
Call Terminal.getInstance().connectReader() with a TapToPayConnectionConfiguration that includes a TapToPayReaderListener and a valid location ID.
Collect a payment with Terminal.getInstance().collectPaymentMethod() and confirm with Terminal.getInstance().confirmPaymentIntent(); the SDK displays the tap UI automatically.
Known gotchas
Android 13 (API 33) is the minimum required OS; the Tap to Pay SDK will return an attestation error on earlier versions.
The Terminal Android SDK 5.0.0 introduced the renamed com.stripe:stripeterminal-taptopay artifact and the TapToPayDiscoveryConfiguration; projects still referencing the old LocalMobile names from SDK v3 must rename all usages.
The device bootloader must be locked and unmodified; rooted devices and devices with Developer Options enabled fail the hardware attestation check required for PIN collection.
