Abstract

A user device including near-field communication (NFC) circuitry may receive a polling message from an NFC terminal. The user device may obtain information based at least in part on the polling message. The user device may determine a characteristic of the NFC terminal based at least in part on the information. The characteristic may be indicative of a radio frequency (RF) field strength of the NFC terminal. The user device may adjust an RF setting of the NFC circuitry based at least in part on the characteristic. The RF setting may correspond to an RF sensitivity of the NFC circuitry.
