The Blocker Tag

Last month, a patent entitled “Method and apparatus for selective blocking of radio frequency identification devices” (patent number 6,970,070) issued at the U.S. Patent Office. As the title suggests (in its vague and formal language), this patent covers the RSA Blocker Tag, an RFID privacy device invented at RSA Laboratories in 2003.
After the whirlwind of trade-press coverage around the Blocker a few years ago, some may be wondering why RSA Security didn’t issue a press release around the issuance of the patent. (It happened very quickly by USPTO standards — in just over two years!) The reason is simple: The Blocker Tag is not likely to become a product anytime soon.
