Iddo Genuth writes, "HP Labs recently revealed a prototype of the Memory Spot Chip, a tiny wireless chip capable of storing and transmitting data. When it hits the market in about 2-3 years, the new chip will enable a variety of applications ranging from digital wristbands that store patient medical information to sound bytes on paper or printed pictures that can be accessed using a reader-equipped device. The article has an interview with Howard Taub of HP Labs and some photos of the prototype chip." The chip can only be read at a distance of 1 mm, so it avoids many of the privacy concerns of RFID. It has about 1000 times the storage capacity and 100-1000 times the data transfer rate of RFID.
