Reducing False Reads in RFID-Embedded Supply Chains

RFID tags are increasingly being used in supply chain applications due to their potential in engendering supply chain visibility and reducing tracking errors through instantaneous location of objects as well as the tagged object’s immediate ambient conditions. During its life-time, an RFID...
