Nicknamed "Powder" or "Dust", the surface area of the new chips is a quarter of the original
Hitachi expects this tiny size will open the way to new applications for wireless RFID chips. The RFID "powder" can be incorporated into thin paper, such as currency, creating so-called "bugged" money.
The RFID Loc8tor can identify special RFID tags from a distance of up to

RFID tags store data, but they need to be brought near special reading devices that beam energy to the chips, which then send information back to the readers.
The technology is already widely used to track and identify items, such as monitoring the distribution of food products or guarding against forgery of concert tickets.
Shown to the public for the first time earlier this month, the new chip is an improvement on its predecessor from Hitachi — the
The latest chip, which still has no name, is
One catch is that the new chip needs an external antenna, unlike the
The smallest antennas are about 0.16 inches — giants next to the powder-size chip.
There are no plans yet to start commercial production of the new chip, Takeuchi said.
Invisible tracking brings to mind science-fiction-inspired uses, or even abuses, such as unknowingly getting sprinkled with smart-tag powder for Big Brother-like monitoring.
"We are not imagining such uses," Takeuchi said, adding that the latest chip is so new — and so miniature — Hitachi is still studying its possible uses.
