Abstract:
An NFC-enabled device (12) comprising a host (22), an NFC interface (26) and an RF transceiver (24) configured to emit a first RF field (46) to power-up one or more in-range RF barcodes (16, 60), the NFC-enabled device (12) being configured to detect the presence of an RF barcode (16, 60) upon powering it up and being configured to read data (48, 62 ) from the one or more detected, in-range RF barcodes (16, 60), characterized by the NFC-enabled device (12) periodically (42) emitting the first RF field (46) and being configured to transmit only changes (64) in the read data (48, 62) from the or each RF barcode (16, 60) to the host (22). The invention therefore presents several advantages, namely: it can improve the user's experience by keeping the listen mode active, even in the presence of a nearby Kovio Tag; and it can save battery power by performing a periodic Kovio tag detection instead of a continuous one.
