Abstract
Disclosed are various embodiments for pick verification using moving radio frequency identification (RFID) tags. A robotic picker moves an item storage structure within range of a radio frequency identification (RFID) tag reader, wherein the item storage structure comprises multiple items and the items each have an RFID tag affixed. The RFID tag reader emits an electric field. The robotic picker moves the item storage structure while the RFID tag reader emits the electric field. An RFID tag identification device receives responses from energized RFID tags affixed to the items. The RFID tag identification device determines that an energized RFID tag is in motion and selects an identifier broadcast by the energized RFID tag that is in motion.
