They are the new generation of bar codes, however not like bar codes, they’ll speak back and that they are often therefore minute that you simply don’t even apprehend that you simply are carrying one. I say ‘wearing one’ as a result of at the instant they’re largely being place into clothes, however the day isn’t isolated once they are going to be below each label of each will of food that you simply purchase.
