What a bad piece. Optical is obsolete. Decathlon (here in France at least) has RFID on all their products, they're used as anti-theft, automatic tilling: you just put them in a box at the register and it knows what it is (also kills the chips once paid) and very likely they're used all along the logistic chain.
Can any regular smartphone scan those RFID tags? If not, then the QR codes are superior because they can be scanned, making it trivial to use them for product recalls.
