Supported Devices & NFC Tap Location

A guide to compatible Android devices for Tap to Pay, device requirements, and where customers should tap their card on each device.

Device Requirements

To accept Tap to Pay on Android, the merchant's device must meet all of the following requirements:

Eligibility Check

The SDK provides a built-in eligibility check that verifies all device requirements before attempting a transaction. Call getKiCEligibility() to confirm the device meets all criteria:

val eligibilityMap = KiCThinClient
    .getInstance()
    .getKiCEligibility(applicationContext)

val failures = eligibilityMap["FailureList"]
if (failures.isNullOrEmpty()) {
    // Device is eligible for Tap to Pay
} else {
    // Handle ineligibility — inspect failure codes
    failures.forEach { code ->
        Log.w("TapToPay", "Eligibility failure code: $code")
    }
}

Tested & Certified Devices

The following devices have been tested and certified by Visa for use with the Kernel in the Cloud (KiC) Tap to Pay Ready application:

Full Supported Device List

Beyond the Visa-certified list, Tap to Pay on Android is supported across a wide range of manufacturers and models. The following devices are confirmed compatible (when running Android 12+):

NFC Antenna Location & Tap Guidance

The NFC antenna location determines where the customer should hold or tap their contactless card or device. Getting this right is critical for a smooth payment experience.

General Rule

On virtually all Android phones, the NFC antenna is located on the back of the device, in the upper-center area (roughly behind the rear camera module). Customers should hold their card flat against the upper-middle portion of the phone's back.

NFC Antenna Location Summary

The table below summarizes NFC antenna placement by manufacturer. For per-model details, see the device tables in the Full Supported Device List above.

Visual Tap Guide

For the best tap experience, instruct customers to:

1. Remove the card from any wallet or sleeve — Other cards or RFID-blocking material can interfere with the NFC signal
2. Hold the card flat against the back of the phone — Do not tap at an angle
3. Position the card over the NFC antenna zone (upper-center back on most devices)
4. Hold steady for 1–2 seconds — Do not pull away until the phone confirms the read
5. Listen/watch for confirmation — The device will display a status message and/or vibrate when the card is read successfully

Handling Tap Failures

If the card does not read on the first attempt:

1. Reposition the card slightly — move it toward the camera area
2. Ensure the card is flat and not angled
3. Remove any phone case that may be interfering
4. Check that the device screen shows the "Present card" or "Tap card" prompt
5. If the issue persists, the SDK will surface an appropriate display message or an OnFailure status code such as NFC_NOT_AVAILABLE
