Untrue argument that supermarkets will use these.
It’s is not true that every item in a supermarket will be tagged with 5G devices. This claim had been made before with RFID tags.
Every item would be automatically scanned when you left the supermarket. Except that it was too expensive and it did not work as expected.
The too high price for RFID tags is 7 cent per tag. This already exceeds the profit margin for most food products up to 5 US$.
