Automatic product inventory management for retail store

A non-transitory computer readable medium containing instructions that when executed by at least one processor cause the at least one processor to perform operations for automatically generating replenishment alerts based on signals from a plurality of wirelessly tagged products, the operations comprising:

• receiving from a plurality of receivers at varied distances from an electronic article surveillance (EAS) gate in the establishment, a first set of wireless signals from the plurality of wirelessly tagged products, wherein each of the first set of wireless signals reflects an ID associated with each of the plurality of wirelessly tagged products;
• receiving from at least one receiver separated from the EAS gate and closer to the EAS gate than the plurality of receivers, a second set of wireless signals from at least one tag associated with at least one of the plurality of wirelessly tagged products, the second set of wireless signals from the at least one tag including an indication, wherein the indication indicates that the at least one tag senses a proximity to the EAS gate;
• accessing at least one data structure associating each ID of each wirelessly tagged product with one of a plurality of product models;
• performing a look-up in the data structure of a product model associated with each ID of each wirelessly tagged product included in the first set of wireless signals and in the second set of wireless signals;
• determining, based on the look-up, a total number of units of each product model detected in the establishment and adjust the total number of units of each product model according to a number of units exiting or entering establishment based on the indication included in the second set of wireless signals;
• accessing in the at least one data structure a target threshold of units associated with each product model in the establishment;
• comparing the determined total number of units of each product model with the target threshold to determine when a particular product model falls below an associated threshold;
• and
• outputting a replenishment notification for the particular product model.
