RFIDsec Unveils Privacy-Protected Tags
June 22, 2006By Jonathan Collins
... These tags were designed specifically to protect consumer privacy.
The tag's microchip operates at 13.56 MHz and is based on the ISO 14443-A standard. RFIDsec will be selling tags embedded in RFID labels. The tags work in conjunction with access-management software that permits the encoding and reading of the tag, as well as a product-authentication application to enable owners of tagged products to authenticate the tags. This is designed to ensure that the original tag has not been tampered with, cloned or otherwise compromised.
