RFID tag sensitivity

A computer program product (CPP) tangibly embodied in an information carrier, the computer program product containing instructions that, when executed, cause a processor to perform operations to determine the sensitivity of a radio frequency identification (RFID) tag, the operations comprising:

• measure the sensitivity of a tag by stimulating the tag with radio frequency (RF) signals at least once at each of a plurality of field strengths and attempting to read the tag at each of the plurality of field strengths;
• store one or more values that represent the measured sensitivity in an information repository;
• and
• associate the stored values with an identifier that is uniquely associated with the tag.

A method of commissioning a radio frequency identification (RFID) tag for use in an RFID system that tracks the movement of article through a supply chain, the method comprising:

• measuring the performance of an individual RFID tag;
• encoding the RFID tag with a unique identifier;
• associating the unique identifier with a first information representing the measured performance;
• storing the first information and the unique identifier in an information repository;
• and
• coupling the tag to an article to be tracked as the article moves through the supply chain.
