Environmental concerns lead Deutsche Post to RFID
Deutsche Post World Net has launched a project to develop passive RFID tags incorporating a small, rewriteable display for use on mail containers. The D-RFID tags, as they’re called, will be used as part of an RFID application under development to track DPWN’s 6 million yellow shipping containers. The company utilizes the crates to hold the 70 million letters that pass through its 84 distribution centers each day.
DPWN currently throws away about 500 million of these paper labels per year. Printing 500 million labels annually is still the cheapest way for it to label the reusable plastic bins, however, so the company initiated a project called Pariflex (Passive RFID with Flexible Bistable Display) to eliminate this environmental waste. D-RFID tags are high-frequency passive RFID tags with displays powered by the tags, which draw their energy from the magnetic field of the RFID interrogator.
The Pariflex project got rolling in October 2005 and will run until September 2008, funded with euro2.5 million (USD3.3 million) from the German Federal Ministry and Research (BMBF). The companies involved will also contribute to the budget if government funds don’t cover expenses, said Gerhard Stönner, DPWN’s head of engineering in the mail division and a manager of the D-RFID project. So far, the partners have developed demonstration tags with the full functionality needed by the application, though these tags contain batteries.
