Description

technical field

[0001] The invention belongs to the field of RFID (radio frequency identification), in particular to object tracking technology utilizing RFID equipment. More particularly, the present invention relates to an apparatus and method for identifying motion and location of objects using RFID devices. Background technique

[0002] Currently, barcodes can be used to track participants as they enter the area via an entrance to the area, but barcodes cannot be used to keep track of where participants go. However, RFID devices can be used to keep track of objects and goods while they are within the RFID coverage area. Successful object tracking depends primarily on the accuracy of the captured object location data, whereby RFID device deployment depends on the accuracy of the captured data for object tracking, whether active or passive RFID technology is used. play an important role.

[0003] Existing technologies using passive RFID for object tracking mainly use an...
