• ### RFID signalling to stimulate reuse of personal computers

Publication Year: 2008, Page(s): 1
| | PDF (78 KB) | HTML

A major obstacle to second hand use of computers is a lack of faith among buyers in the quality of the hardware. In the absence of a means for sellers to communicate system quality to buyers, the true value of second hand systems cannot be verified. This leads to sellers of quality goods having to accept a price which is less than the value of the system. Owners of high quality systems will be unw... View full abstract»
