Passive RFID customer service enhancement using fuzzy logic

When customers who carry their “Hospitality” cards (UHF passive RFID tags) enter the shopping malls, the RFID reader can identify the tags and get the customers´ personal information. The position of the customer can also be obtained using the reflected RSSI value returned to the RFID reader from the RFID tag. These information can help sales assistants to provide proper service to customers. In this paper, we propose an enhancement scheme for customer service using fuzzy logic system (FLS) using RFID. Three antecedents are used: the distance of a customer to the corresponding area´s salesman, the walking speed of the customer and the possibility that the customer accepts recommendation. 27 FLS rules are set up based on these three antecedents. The output of the FLS provides the service possibility that the sales assistant at the corresponding area will provide proper service to the customer. If a customer is near to the salesman, the walking speed is slow and the possibility of acceptance of recommendation is high, then the possibility that the salesman provides service is strong.
