No hiding place for anyone

Sep 20th 2001

Embedded in bank notes or designer labels, the "mu-chip" can beep out the owner's location and details to marketers and thieves alike

IN TODAY'S information age, everybody leaves an electronic trail in their wake. With every credit-card purchase, ATM transaction, telephone call and Internet logon, they create an electronic portrait of themselves that grows clearer at every step. Perhaps the only items that are still untraceable are people's clothes, cash and day-to-day movements. But with the introduction of Hitachi's new "mu-chip", even these could become common knowledge.

The Hitachi chip is the world's smallest wireless identification device. It measures 0.4 millimetres square and is thin enough to be embedded in paper. It can hold only 128 bits of read-only memory, and do little more than spit out a unique identification number, when asked, to a distance of about 30 centimetres. It uses the same frequency band (2.45 gigahertz) as such longer-range wireless networking technologies as Bluetooth and 802.11b. But with the mu-chip's tiny size come some large implications.

Until now, size and production cost were the main obstacles that stopped companies from embedding identification chips in everyday items. But Hitachi has managed to create an integrated circuit that is not only tiny but cheap. The company expects a single chip to cost less than ¥20 (16 cents).

One (more) possible application could be clothing or jewelry for children (or anyone, for that matter) which could be activated in the event of a kidnapping. As with any technology, how it's used is more important that what it is.
