The Supertag® developmentsSupertag ® 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.
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.
