The efficiency and dynamic data access of RFID systems are major advantages compared to general or even two-dimensional barcodes. As RFID systems become common in daily life, maintaining quality of service provided by such devices, such as issues related to sensing error and data loss, pose considerable challenge. These issues are particularly important in developing a system for the rapid checkout of multiple items in shopping carts. Since these items are located haphazardly in shopping carts: (i) tags are located in various distances and angles relative to the reader; (ii) some items may be blocked by others; and (iii) one RFID reader may interfere with other readers or wireless networks. This paper explores QoS issues related to RFID systems. According to the results of our experiments, we propose a number of suggestions to improve RFID system for the rapid checkout of a large number of items.
