TAG DEVICE, TRANSCEIVER DEVICE AND TAG SYSTEM

摘要

An ID is periodically transmitted at a first frequency (f1) from a tag device (10). When the ID is received by a transceiver device (20), the ID is reported to a higher-level device (H). When the transceiver device (20) receives a command from the higher-level device (H), the command is transmitted at a second frequency (f2). When the tag device (10) receives the command, processing is performed to a peripheral device (4) in accordance with the command, and a user ID is transmitted at the second frequency (f2). When the user ID is received by the transceiver device (20), the user ID is reported to the higher-level device (H).
