Hey you just ate the RFID chip along with food
Next time you open up the food package do it cautiously or you might end up eating one of those tiny RFID chips along with the food. In this year’s ISSCC (International Solid-State Circuits Conference) Hitachi is showcasing a 7.5 micron thick RFID chip. It will measure 0.15×0.15mm in dimension and will be 10 times thinner than a sheet of paper. (seen below is a 0.4×0.4mm chip)
Happy eating.
