While setting up mobile payments on a new tablet, a user finds that the device cannot establish a connection with the payment terminal even though the terminal is operational. As a technician, which hardware component on the user's tablet should you check first to resolve the issue?
Ensure the tablet's GPS receiver is activated
Verify that the NFC module is installed, enabled, and functioning
Test whether the tablet's webcam is operational
Confirm that Bluetooth is enabled and searching for devices
Tap-to-pay mobile payments require the tablet's near-field communication (NFC) radio and antenna to be present and enabled so the device can exchange payment data with the terminal at a range of a few centimeters. If the terminal is working but the tablet cannot connect, the NFC module (antenna/chip) is the most likely point of failure or misconfiguration. A webcam, Bluetooth radio, or GPS receiver are unrelated to the NFC link used for contactless payments.
