Description
Book SynopsisRFID (Radio Frequency Identification) is a new supply chain management system that will eventually take the place of traditional barcode scanning. Many companies have already announced their shift to RFID technology and even more will shortly follow suit. This means that other businesses will have to implement RFID at their end.
