Teeny Tiny Hitachi RFID Chip: Big Whoop

This image was lost some time after publication.

Smaller than a grain of salt, Hitachi's newest RFID chip measures .005 x .005 inches and is 7.5 micrometers thin. Using Silicon-on-Insulator (SOI) technology, it uses an external antenna to receive radio waves (2.45 GHz), and transforms it to energy to wirelessly transmit a 128-bit unique ID number for a high level of authenticity. But most importantly for Hitachi, it can make more of these chips on one single wafer, increasing production by four times.

Most importantly for you, expect to see more and more embedded RFID chips in nearly every product you purchase.
