These RFID chips are made by Hitachi. The ones in blue have 128 bits of ROM and can store a 38-digit number. They are billed as being the smallest RFID chips and are 64 times smaller than the tiny chip you see on the person’s finger (right). The black line you see in the middle photo is a strand of human hair. Hitachi reps have said they don’t know what they’re going to do with the tiniest chips, which are being called “RFID powder” for now. You can read more about the chips here.
