There has been a lot in the news lately about RFID as a supply-chain replacement for barcode. As a barcode replacement, RFID has a lot of benefits. There are other uses of RFID, though.
American Express was one of the first to release a credit card (Blue) with an embedded RFID chip. They also offered a free USB port connected reader that could be used to read the info from the card and enter it into eCommerce applications that were ennabled for the card. I actually ordered one. Still have it. Never used it.
Now RFID is rearing its head in international territory. The PASS card will replace the Passport for entry into certain countries. Take a look at the article below for more information.
