Abstract:
A NFC reader is connected for communication to NFC devices such as an NFC-A device and an RF barcode device. The reader detects and logs the active and sleep intervals of the RF barcode device in response to receipt of periodically received UID communications. The transmission and reception of data to and from each NFC-A device is then synchronized to occurs only when the RF barcode device is in a sleep interval between UID communications.
