Terminal for line-of-sight rfid tag reading

A terminal for use in converting an electronic product code (EPC) into a decoded bar code, the terminal comprising:

• one or more processors;
• a computer readable storage medium;
• first program instructions to convert a manager number of the EPC into a manufacturer code;
• second program instructions to convert an object class of the EPC into a product code;
• and
• third program instructions to construct the decoded bar code from the manufacturer code and the product code;
• wherein the first, second, and third program instructions are stored on the computer readable storage medium for execution by the one or more processors.

A computer program product for determining which of one or more candidate radio frequency identification (RFID) tags having unique data stored thereon is a target RFID tag within a line-of-sight of a terminal, the computer program product comprising:

• a computer readable storage medium;
• first program instructions to direct an image sensor of the terminal to capture one or more frames of image data within the line-of-sight of the terminal;
• second program instructions to determine, from the one or more frames of image data, whether an object is present in the line-of-sight of the terminal;
• third 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 is present in the line-of-sight of the terminal;
• fourth program instructions to calculate an accumulated received signal strength indication (RSSI) of each of the one or more candidate RFID tags;
• and
• fifth program instructions to determine the target RFID tag from a highest accumulated RSSI;
• wherein the first, second, third, fourth, and fifth program instructions are stored on the computer readable storage medium.
