Abstract
A radio frequency identification device is configured as a data logger. In a logging mode the radio frequency identification device logs information received from a transmitter. In an upload mode the radio frequency identification device is configured to upload to a receiver logged information and/or information identifying the radio frequency identification device. Optionally, the logging mode is used when there is insufficient power to send a readable response signal to the transmitter.
