The future of RFID technology could go as far as the Moon or Mars, according to a recent Technology Review article. RFID tags hold great promise for tracking inventory, which could turn out to be a huge timesaver to astronauts that need to deal with supplies and equipment. You definitely do not want to embark on a lengthy mission only to discover you left a key piece of equipment behind, but you also don't want to spend valuable mission time double-checking supplies on your exploration vehicle. Also, RFID could prove useful if NASA stockpiles supplies in space, for use in future missions.
