Abstract: A discovered NFC-B listen mode device is put to SLEEP state only when there are one or more NFC-B listen mode devices yet to be discovered. An optimal value for the number of time slots indicated in a command is computed based on a combination of whether an empty time slot was detected and/or collision was detected and/or an NFC-B listen mode device was discovered in a discovery cycle. The compliance with the NFC Forum Activity Specification allows the direct activation of an NFC-B listen mode device, and thus speeds up the data transfer phase and consumes much less power.

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.
