An ultra-small RFID chip: /spl mu/-chip

An ultra-small (0.3 /spl times/ 0.3 /spl times/ 0.06 mm) radiofrequency identification chip, called the /spl mu/-chip, has been developed for use in a wide range of individual recognition applications. The chip is designed to be thin enough to be applied to the paper and paper-like media widely used in retailing to create certificates that have monetary value, as well as to tokens. It was designed and fabricated using 0.18-/spl mu/m standard CMOS technology.
