Chipless RFID tags, on the other hand, function without a communication protocol. They employ a grid of dipole antennas that are tuned to different frequencies. The interrogator generates a frequency sweep signal and scans for signal dips. Each dipole antenna can encode one bit. The frequency swept will be determined by the antenna length.
Some RFID tags offer additional read/write user memory that could be used for storage of additional information, such as an expiry date or date of manufacture. Plain text and barcoding are still useful in addition to the EPC tag, as liability obligations for the producer require durable and sufficiently fail-safe labels.
