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 Optical is obsolete.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.
Decathlon does it in every country, not just France. Same with Uniqlo and a few others, but it's still only very large chains that can afford it
Merchandise point-of-sales tags isn't the only use of barcode or QR codes. Hospitals aren't going to start putting RFID for all equipment, files, and patients.
And what is average price of one product in Decathlon compared to Lidl? Apples and oranges. How do you put RFID on fruit, vegetables and pastry btw. or you propose wrapping everything in unnecessary packaging?
Putting a chip on everything sounds wasteful and worse for the environment than a printed piece of paper. Not the right direction to go in.
