  • SYSTEM AND METHOD FOR MANAGING COMMUNICATION BETWEEN CONTACTLESS DEVICES
    Publication number: 20230387965
    Abstract: The disclosure relates to a modified NFC framing is used by a reader and selected devices during at least a part of the communication between the reader and the selected devices. The reader and the selected devices store modification rules for modifying the frames. Devices not storing those modification rules will discard the received modified frames.
    Type: Application

  • Method for distinguishing between active and passive contactless devices, and corresponding reader
    Patent number: 11416692
    Abstract: An embodiment method comprises transmitting a reader carrier signal from a contactless reader to a contactless device, receiving by the reader, a device modulated carrier signal from the device, the device modulated carrier signal having a carrier frequency, preferably turning off by the reader, the transmission of the reader carrier signal during reception of the device modulated carrier signal, and after having turned off the transmission of the reader carrier signal, determining by the reader the presence or the absence at the reader's antenna of a modulated carrier signal having at the reader's antenna the carrier frequency with a tolerance, without relying on the data content of the modulated carrier signal.
