Abstract

Methods and systems for monitoring one or more products by grouping the products into lots are described. Methods and systems of the present invention provide significant benefits over adding an RFID tag to represent and monitor a group of products. For example, the present invention simplifies data management by monitoring information associated with lots, rather than each individual product. In addition, information pertaining to all products included in a lot may be obtained by although only a small portion of products in the lot can be identified.

f) identifying the lot based on the data read in step e); and

g) retrieving data pertaining to the first product, the second product, or the first and second products from the collective data to monitor the one or more products in the lot.

10. The method of claim 9, wherein the method for monitoring one or more products comprises a computer-implemented method, and

wherein a processor groups the first product having the first RFID tag responsive to the first frequency range and the second product having the second RFID tag responsive to the second frequency range to obtain the lot, stores the data associated with the first and second products in the repository, stores the at least one additional data associated with the lot in the repository to generate the collective data, identifies the lot based on the data read, and retrieves the data pertaining to the first product, the second product, or the first and the second products from the collective data to monitor the one or more products in the lot.
