AisleBuyer is an app-based self-checkout solution for offline retailers. It offers a virtual shopping assistant, a "location-aware" digital circular, and a mobile self-checkout system. By scanning product barcodes, customers can access product information, targeted offers, and reviews. They can also browse the entire product catalog of participating retailers. AisleBuyer aims to increase sales, reduce costs, and provide retailers with analytical insights into customer shopping behavior. The iPhone application allows users to scan barcodes, check pricing, and complete purchases.
