I don't really understand the question. Any comparison of radio frequency identification and bar codes doesn't change year by year. Perhaps a few new RFID products might further increase the technology's capabilities, but generally speaking, the advantages of using RFID for some applications don't change with time. I would encourage you to read my post of Sept. 1, "How Is RFID Different From Bar Codes?"
