I vividly recall seeing a feature on TV in the mid 80s where they were discussing future technologies for the year 2000. One of them was the cashier-less store: We'd all put in our grocery items in the carts and then the payment would be automagically calculated, no cashier or manual scanning necessary. They assumed it would be microchip based, the chip embedded in packaging. What ever happened to this? Why did this…
However, because RFID chips are too weak to be reliably read in bulk and at a distance, you need to deposit your items one by one in a special trough that scans them. And this is only possible because both Uniqlo and Decathlon are 100% house brand and can thus ensure the chips are present in everything, which is why random corner stores or supermarkets can't copy them.
