I first saw this system at a Texas Instruments demo in the UK in 2007-ish. They also demoed walking through a RFID reading gate with a trolley full of tagged goods. I thought it was very cool at the time but I assumed it must have been too impractical for some reason until Decathlon rolled it out in 2019.
