RFID gets so much press in supply chain and retail applications that we can forget all the other places where the technology plays a role. For instance -- libraries.

The Library Journal reports that "3M is marketing new RFID tags designed specifically for CD and DVD collections. Dubbed 3M CD8 RFID, when coupled with special software, the tags link the discs with the jewel cases as a set, assuring that discs and cases are the correct match when returned. According to 3M, the 'sets feature improves checkin accuracy and reduces the handling of materials to save staff time.' The sets feature also prevents patrons from checking out empty cases or cases containing the wrong discs."

There's even a blog just for RFID in library settings, called RFID in Libraries.

Stay tuned...in our next post we'll examine another use of RFID in connection with DVDs. This time it will be totally unrelated to libraries.
