The combination of QR Tags with unique, dynamic IDs and physical products delivers plenty of new possibilities. Not only online shopping is possible, but also the sale and reservation of articles and products even if local stores are closed. Customers can be led to corresponding additional products and accessories to an already chosen product and a higher engagement supports customer loyalty and trust. In addition, there is a two-way communication: on the one side the information about products or brands that goes out to the customers and on the other side the data which can be collected about customer and consumer behaviour. These insights are the basis for an effective and customized marketing, offer the possibility to compare the performance of different locations and can help to improve specific store campaigns.
