The Hitachi µ-Chip that Fits into Paper

Hitachi invented a chip with Radio-frequency identification, a remotely data retrieving technology, and called it the µ-Chip.
It uses a wireless semiconductor integrated circuit storing an ID number in its memory.

This type of chip measures just 0.15 mm x 0.15 mm x 0.0075 mm, 0.4mm square, meaning more little that grain of rice, and looks like in the picture.
The µ-Chip has 128 bits of ROM memory, meaning the ID number that can be stored can have maximum 38 digits.

It is not as complicated as a standard IC chip but its applicability could be larger because of its tiny dimension.
More than that, its memory can be written only when it is manufactured and impossible to change later, so, if embedded, it would be perfect for authentication of cash money for example, or even clothing.

The frequency it uses is of 2.45GHz and besides that its Read Only Memory cannot be written or read, it has also anti-collision capabilities.
In conclusion, the number stored in could be used individually to identify trillions of trillions of objects without duplication.

We hope that Hitachi’s chip will soon have a commercial application.
