Abstract
Methods and apparatus to visualize locations of radio frequency identification (RFID) tagged items are described. One example method includes processing received Radio Frequency (RF) waves to determine a location of one or more radio frequency identification (RFID) tagged items, indicating the location of one or more RFID tagged items via a portable electronic device configured with a visual display, receiving at the portable electronic device product information associated with a selected individual RFID tag, receiving at the portable electronic device one or more inputs to modify the product information associated with the selected individual RFID tag, and transmitting the modified product information associated with the selected individual RFID tag from the portable electronic device to a database.
