Abstract
An example radio-frequency identification (RFID) tag assembly includes: a first tag comprising: a first antenna configured to receive a first radio-frequency signal; a first circuit interconnected with the first antenna, the first circuit configured to be powered by the first radio-frequency signal and to control the first antenna to transmit first tag identification data; and a converter configured to convert energy from the first radio-frequency signal to storable energy; and a second tag comprising: a second antenna configured to transmit second tag identification data; and a battery configured to store energy to power the second tag and provide the stored energy to the first tag in response to a power sharing condition; wherein the converter is further configured to provide the storable energy to the second tag for storage in the battery in response to a power storage condition.
