Smart price tags can interact with applications on customers' smartphones. For example, sensors installed on shelves can tell when you are approaching them, so they can show the price of the same bread you bought last week. In addition, if you use a store application to create a shopping list, the smart shelf can interact with the list and tell you where to find the goods you want. Although there are privacy and data collection issues, some consumers share their personal information and purchase history to conclude transactions.
Radio Frequency Identification Reader (RFID) usually has a tag, which contains a microchip, reader and antenna to transmit and receive data. It uses radio waves to identify objects and transmit information about them. In supermarkets, RFID technology can help retailers manage and track inventory. RFID tags can alert shop assistants when the shelves are empty, need to be re-stocked, or someone puts the wrong goods on the shelves. The combination of RFID tags on each item and robot checkout can automatically scan your purchases and make shopping faster.
Internet of Things (IoT) sensors have many potential uses in supermarkets, among which temperature control is the most basic. Internet of Things sensors can detect temperatures in refrigerators and boxes to make sure they are correct, lest fluctuations destroy all ice cream or make all meat sales dangerous. The Internet of Things can also collect data from smart shelves and transmit it to storage partners for analysis. This technology can help supermarkets understand which products are attractive to consumers and how stores arrange display.
Smart price tags will change the way you shop in the future. From digital displays showing real-time price changes to ads linking to shopping lists, you can expect this technology to become more personalized.
