Hitachi Unveils its Itty Bitty RFID

Taking the concept of e-commerce in new directions, Hitachi (Quote, Company Info) Tuesday unveiled one of the world’s tiniest RFID chips with an internal antenna.

The Tokyo-based firm said its new 0.4 by 0.4 mm chip could be embedded in bank notes, gift certificates and other paper documents. The previous iteration of Hitachi’s u-chip, announced in 2001, was as small, but needed an external antenna to communicate with the reader, limiting its application. The new chip is compatible with ID number and support systems for the original u-chip. []
