Hewlett-Packard researchers have developed a miniature wireless data chip that can be stuck on or embedded in any object.

HP said the device could be used to store medical records on a hospital patient's wristband, add security to identity cards and passports, and supply additional information for printed documents.

The experimental chip is a CMos-based mem­ory device about the size of a grain of rice and with a built-in antenna.

The chip receives power through inductive coupling from a special read-write device which extracts content from the memory.
