Systems and techniques for linking electronic shelf labels to and unlinking electronic shelf labels from a system. When a printed overlay for an electronic shelf label is prepared, a radiofrequency identification (RFID) tag is affixed as part of the overlay. The RFID tag provides an identifier associated with a product. When an ESL to which the overlay is affixed is to be linked, the RFID tag is read at substantially the same time the ESL is interrogated, and the product associated with the RFID tag identifier is associated with the ESL. When an ESL is to be unlinked, a communication including an identifier for the ESL is provided to a central data processor, with the communication having characteristics indicating that the ESL is to be unlinked. When a communication is received from an ESL, the characteristics of the communication are evaluated to determine if the ESL is designated for unlinking. |
