Compaction of RFID Devices Using Data Compression

When a coding system used to represent letters or numbers in transmitting messages has many unused codewords, it will be more than reasonable to compress the messages. Electronic product code (EPC) which is widely used by many RFID devices has plentiful unused codewords. As a matter of fact, the unused codewords are most by far of the codewords. In this paper, we check the suitableness of a commonly used compression algorithm for EPC of RFID devices.
