CASPIAN
Consumers Against Supermarket Privacy Invasion and Numbering (CASPIAN) is a USA grass-roots consumer group dedicated to fighting supermarket "loyalty" or frequent shopper cards. CASPIAN's efforts are directed at educating consumers, condemning marketing strategies that invade shoppers' privacy, and encouraging privacy-conscious shopping habits. CASPIAN also spreads information and opinions that purport to warn the public about the privacy risks associated with universal adoption of RFID technology, including microchip implants. CASPIAN refers to RFID tags as "spychips."
CASPIAN was founded in October 1999 by Katherine Albrecht.
Microchips and Cancer Report
In November 2007, CASPIAN released a research report Microchip-Induced Tumors in Laboratory Rodents and Dogs: A Review of the Literature 1990–2006 by Katherine Albrecht, Ed.D. which is a meta-study of previous research. The report cites medical journals where between 0.8% and 10.2% of inbred laboratory mice and rats developed foreign-body tumorigenesis at the site of a microchip implant.
