Law Firm Uses RFID to Track Every Page of Confidential Documents

The firm utilizes a system provided by Lexmark, Plus Technologies and ATM Software Solutions to print RFID-enabled documents with a unique ID for each page.

May 10, 2012RFID-based document-tracking solutions have become commonplace in such locations as legal and medical offices. But one law firm has taken that solution to a new level, by tagging and tracking every sheet of paper for its most sensitive files, in order to ensure that it knows where ever page is located, and that nothing is ever misplaced. The solution was a collaborative effort provided by printer manufacturer Lexmark, using Plus Technologies' tag-identification software, as well as software and RFID readers supplied by ATM Software Solutions.

From the onset, it was a highly confidential implementation aimed at providing an efficient method for printing documents, each page containing an RFID tag encoded with a unique identifier. The law firm, which has asked to remain unnamed, creates documents in courtrooms or elsewhere, prints those documents and then tracks them as they are moved around its offices and are eventually destroyed. The firm produces thousands of such highly sensitive pages daily, and sought to track each page individually.

The law firm is using a Lexmark T654 laser printer with a built-in EPC Gen 2 RFID reader.

With the system in place, a law firm employee can use a computer to create a document, including a title indicating that document's level of confidentiality, and then direct it to be printed on the Lexmark printer. Plus Technologies software, residing on the law firm's database, intercepts the print stream, says Mike Visser, Plus Technologies' president, and to ascertain each document's confidentiality level. The software opens the document to determine the number of pages contained within, and then creates a unique serial number for each page.

The ID numbers are stored along with a listing of each page in the software, and the document is then printed on the Lexmark T654 laser printer with a built-in RFID reader-encoder and multiple paper drawers—one for creating documents with embedded RFID tags, the others for non-RFID documents. In the case of a confidential page that has been assigned a unique identifier, the printer employs media provided by eAgile, consisting of paper containing Avery Dennison AD-224 passive EPC Gen 2 ultrahigh-frequency (UHF) RFID tags, which are similar in size and appearance to a small Band-Aid, and are affixed near the top of the page.
