Abstract
A process for performing Near Field Communication (NFC) between a first NFC device and a second NFC device is provided. The first NFC device includes an NFC transceiver and an FM receiver which are both integrated into the same chip. The provided process involves initializing the first NFC device to perform a device detection polling loop for detecting a second NFC device. The device detection polling loop has activity detection periods, which occur periodically. The first NFC transceiver may then perform a slicing procedure, which slices the activity detection periods into small time slots. Each time slot has a duration smaller than a predetermined value so as to reduce the noise generated by harmonics of the NFC operation frequency which might be audible to the user.
