Computer Chip

Hitachi has developed a new RFID chip, one that is much smaller than existing chips. This new chip is not that much bigger than the size of a grain of sand.

RFID stands for “radio frequency identification.” RFID chips are tiny computer chips embedded into products and animals (and sometimes people) to identify and track them. The chips send a signal that can be read by a decoder.
