There is provided a terminal (1000) for use in determining which of one or more candidate RFID tags (608 ABCD) having unique data stored thereon is a target RFID tag (604) within a line-of-sight of the terminal. The terminal can comprise program instructions to direct an RFID reading device of the terminal to perform a number of reads of the one or more candidate RFID tags in response to determining that an object (602) is present in the line-of-sight, to calculate an accumulated RSSI of each of the one or more candidate RFID tags, and to determine the target RFID tag from a highest accumulated RSSI. In one embodiment, the unique data can be an EPC. There is also provided a terminal for use in converting an EPC into a decoded bar code. The terminal can comprise program instructions to transmit the decoded bar code to a computer such as an electronic cash register (700). |
