The Trouble with RFID
Some groups and individuals in the RFID industry are pushing to encrypt chip information, but cost is the hurdle facing RFID security advocates. Standard RFID chips hold limited data. Chips with greater storage capacity cost more money and require framework to support them. This leads to increased costs, and increased costs make many tagging purposes economically infeasible. When the new RFID enabled passports were in development, the U.S. government made the decision not to encrypt the information at all mainly to reduce cost. Only after significant public outcry was it decided that the passport data would be incorporate low-level encryption. The result is a RFID passport data that can be cracked in relatively little time. The money saved does not appear to be worth the compromise anymore.
