The RFID based solution would be to embed each part as it comes in with an electronic label (an RFID tag). The RFID tag would have a unique ID number which is linked to the material database, having all relevant information about the part. The electronic labeled part is now put into a smart shelf.The smart shelf is composed of a built in antenna and an RFID reader, which keeps track of all the RFID tags inside (the medical parts).
