RFID technology transmits a pre-programmed serial number using radio waves. The programmed RFID tags can then be scanned to track the movement of products.
Plus Technologies developed the software for a law firm that wanted to use RFID to track confidential documents, but needed to create unique serial numbers on a page-by-page basis to enhance security.
The company’s print system captures unique information about the document, such as the author, date or number of pages, to create a “unique identifier.” This identifier is then “printed” to the RFID tag using special Lexmark printers. The same serial number also is stored in a database that tracks document check-in and check-out.
Plus Technologies officials said the technology also has applications in health care for patient wristbands, as well as other industries.
