Priyank Kalgaonkar / Electronically Connected Intelligent Shelves

The main objective is to reduce loss in revenue due to delayed shelf-restocking (when product is in-stock in the store but not stocked on the shelf) and inaccurate forecasting (under-estimating future product sales) practices. The result is to demonstrate inventory automation using ECIS system by enabling the means to monitor and track store inventory in real-time, perform data analysis remotely in cloud, improve shopping experience for the consumers and increase revenue for the retailers in the retail industry.
