Fujitsu enhances RFID for document management

September 18, 2009:Fujitsu has unveiled new UHF-band RFID document management tags which overcome one of the drawbacks of conventional RFID tags, that could not transmit signals when stacked tightly together.

It is now possible to simultaneously read the new tags even when spaced only 2mm apart in a stack of documents.

As a result, a handheld RFID tag reader can be used to efficiently manage tagged documents, even when they are stacked or packed in boxes. Moreover, whereas it used to take 3 seconds to read the signal from just one document, 100 documents can be read in four seconds

In addition, because the tags can be read while documents remain stored on shelves or in cardboard boxes, the document management tags help to prevent leaks of personal data, enabling secure document management.

The company claims signals from 100 tags can be read simultaneously in approximately four seconds when stacked 2mm apart.

In the past, special compartments needed to be configured to accommodate a fixed reader/writer, stationary antenna, and PC to read the RFID tags. The new tags, however, can be read simultaneously with simply a handheld tag reader.

Signals from each document management tag can be read from up to a distance of approximately 2.5m.

Security measures can be maintained in the handling of documents, such as mailed matter, as they can be read simultaneously even when left stored in a cardboard box or shipping case.
