Hitachi weaves chip into paper money
A tiny identity chip could have massive implications for security - and also for your privacy.
Hitachi has developed a chip that could be woven into paper money to help identify counterfeits, and which could also have wide ramifications for identification and surveillance technologies.
The chip, called Mew, measures just 0.4mm on a side, and stores information such as identification and security code. It includes 128 bits of read-only memory (ROM) and RF wireless circuitry that allows it to transmit over a distance of about 30cm. If inserted in money, a reader unit would be able to instantly detect authentic bills.
