Abstract

A tag apparatus (10) transmits its ID periodically over the wireless at the first frequency. When receiving the ID, a transceiver apparatus (20) notifies an upper hierarchy apparatus (H) of the reception of the ID. The transceiver apparatus (20) when receiving a command from the higher hierarchy apparatus (H), transmits the command over the wireless at the second frequency. Upon receiving the command, the tag apparatus (10) conducts a processing action of a peripheral apparatus (4) determined by the command and transmits a user ID over the wireless at the second frequency. When receiving the user ID, the transceiver apparatus (20) notifies the upper hierarchy apparatus (H) of the reception of the user ID.

Claims

1. A tag apparatus (10) including an RF transmitter (11) for communication at a first frequency, an RF transmitter/receiver (12) for communication at a second frequency, and a data processor (13), characterized in that the data processor (13) is arranged to periodically transmit an ID from the RF transmitter (11) while receiving a command with and transmitting a user ID from the transmitter/receiver (12).

3. A tag system (100) characterized in that the tag apparatus (10), which is defined in claim 1, transmits an ID periodically over the wireless at the first frequency, the transceiver apparatus (20), which is defined in claim 2, when receiving the ID notifies an upper hierarchy apparatus (H) of the reception of the ID, and when receiving a command from the higher hierarchy apparatus (H) transmits the command over the wireless at the second frequency, and the tag apparatus (10) when receiving the command conducts a processing action determined by the command.

2. A transceiver apparatus (20) including an RF receiver (21) for communication at a first frequency, an RF transmitter/receiver (22) for communication at a second frequency, and a data processor (23), characterized in that the data processor (23) is arranged to receive an ID with the RF receiver (21) while transmitting a command from and receiving a user ID with the transmitter/receiver (22).
