ELECTRONIC TAG FOR DATA MANAGEMENT

Abstract:

An electronic tag, which may be used in a data management system, comprises a Bluetooth transmitter and an RFID transmitter. The Bluetooth transmitter is operable to transmit first data packets. The RFID transmitter is operable to transmit second data packets. The first data packets comprise a first identifier, ID1, and the second data packets comprise a second identifier, ID2, which is different from ID1. A portable electronic device is configured to, upon receiving one of the first data packets by a Bluetooth receiver, selectively activate an RFID receiver for the second data packets, thereby enabling transfer of ID2 from the electronic tag irrespective of the data transfer capacity of the first data packets.
