Radio frequency identification tag and arrangement and method of associating tag data from the tag with code data from an optical code on the tag

摘要

A radio frequency identification (RFID) tag includes a substrate, and an optical code and an RFID assembly on the substrate. The optical code is encoded with code data. The RFID assembly contains tag data. The RFID assembly is operative for reading the optical code to obtain the code data, for associating the tag data with the code data, and for sending the associated tag data and the associated code data by radio frequency away from the RFID tag upon interrogation of the RFID tag by an RF interrogator.

1. A radio frequency identification (RFID) tag, comprising:
a substrate; an optical code on the substrate, the optical code configured with a series of bars and spaces being encoded with code data; and an RFID assembly on the substrate, the RFID assembly containing tag data and being operative for reading the optical code to obtain the code data, for associating the tag data with the code data, and for sending the associated tag data and the associated code data by radio frequency away from the RFID tag upon interrogation of the RFID tag, and a sampling circuit includes a plurality of pairs of electrically conductive sampling lines over each bar and each space, and wherein each pair of sampling lines is separated by a gap that overlies each bar and each space.
