The R402 uses high-tech RFID technology to recognize and produce labels. The RFID transponder can later be edited for the life of the "smart label." The R402 generates labels perfect for inventory and supply chain management, fast package delivery, baggage tracking, returnable containers and pallets, library and video store product checkout, document tracking and anti-counterfeiting. These smart labels use radio waves and do not suffer from smudges and other common label-reading problems. This makes the R402 ideal for outdoors and other harsh environments. They are also able to be scanned as a group, rather than one-by-one as with traditional barcode labels.
