Aproov Checkout is a mobile advertising service that lets businesses publish deals to smartphones, lets customers reserve coupons and allows businesses to process (redeem) the coupons at the checkout using nothing more than a smartphone or tablet and an Internet connection. No barcodes or QR codes need to be scanned and no additional hardware is required. Every coupon code generated is unique and can only be used by one customer. This allows businesses to track deals and customers and ultimately allows them to perform analysis of campaigns in order to improve their customer relations.
