Detection of groups of RFID tags

摘要

RFID-based inventory management systems are provided for various applications. Such systems include a plurality of RFID-readable products tags, with each product tag being associated with a piece of merchandise and programmed to generate a signal containing information regarding the associated piece of merchandise. Such systems also include an RFID reader capable of sending and receiving signals from the product tags. Such systems further include a processor capable of receiving signals from the RFID reader with information regarding the product tags. The processor compares the information regarding two or more product tags to determine whether they are being moved together as part of a moving group. If the processor determines that there exists a moving group of product tags, it generates an output based at least in part on the signals being sent from the product tags in the moving group.

主权项

1. An RFID-based inventory management system comprising:
a plurality of RFID-readable product tags each associated with a piece of merchandise and programmed to generate a signal containing information regarding the associated piece of merchandise; an RFID reader capable of sending signals to and receiving signals from said product tags; and a processor capable of receiving signals from the RFID reader with information regarding said product tags and programmed to:
compare the information regarding two or more of said product tags,determine whether said two or more product tags are part of a moving group being moved together,generate an output based at least in part on the signals being sent from the product tags in the moving group, andwherein the processor is programmed with a carry limit corresponding to an ability of a person to carry pieces of merchandise and the output generated by the processor is an alert to provide assistance in a vicinity of the moving group of product tags if the moving group exceeds a carry limit.
