  • Anticollision mechanism for an NFC device
    Patent number: 9634725
    Abstract: A device includes near-field communication (NFC) control circuitry and transceiver circuitry. The transceiver circuitry is coupled to the NFC control circuitry. In a reader mode of operation, the NFC circuitry detects reception of NFC polling frames by the transceiver circuitry. When reception of an NFC polling frame is detected, the NFC control circuitry switches from the reader mode of operation to a card mode of operation.
    Type: Grant
    Filed: July 22, 2016
    Date of Patent: April 25, 2017
    Assignee: STMicroelectronics (Rousset) SAS
    Inventors: Pierre Rizzo, Nathalie Vallespin, Emmanuel Papart

  • Anticollision mechanism for an NFC device
    Patent number: 9425862
    Abstract: An anticollision method for an NFC device wherein, in reader mode, a variation of a piece of information representative of the amplitude of the signal in an antenna of the device is monitored, and if this piece of information exceeds a threshold, the device is switched to the card mode.
