wunderbon is the new analytics toolkit for stationary retailers; we provide an independent platform which allows every stationary retailer with an electronic cash register to participate in our program. wunderbon enables retailers to transfer standardized, digital receipts in their corporate branding to the smartphone of their customers and to build a digital relationship with them, based on digital receipts and personal after-sale communication. We analyze the data stream, inside and outside of the retailer's stores, and help the retailer to get a better picture of their customer. This empowers retailers to run tailored advertising campaigns in cooperation with their suppliers (e.g. Cash-Back campaigns). Additional features like product recalls, best-before dates and a smart shopping list are complimentary. wunderbon is one of the most simple, secure and innovative B2B2C platforms, providing the best digital services to his partners and users.
