The Supertag® developments

Supertag ® is the name given to a multiple article scanning low cost RFID technology developed to scan the contents of a trolley(cart) in a supermarket.

Disclaimer
The registered trademark Supertag was owned by CSIR (South Africa) in 1994 and might since have been sold to another party. There is no connection between Trolley Scan and the ownership of the trademark Supertag.

Supertag technology was invented by Mike Marsh and his team while working for the South African Government funded research group named CSIR. Mike Marsh went on to start the private company Trolley Scan but was not allowed to use the Supertag technology, and so he invented the Trolleyponder technology.

This page gives some of the history of the development of Supertag while Mike Marsh worked at CSIR.
