The way people live is changing because of the Internet of Things (IOT), which connects basic household items. Shopping in huge malls is part of everyday life in modern metropolises. On days with predetermined discounts and on holidays, one can observe a huge rush in shopping malls. People buy various things, put them on shopping carts and then go to the checkout to pay. In order to have their goods scanned with an RFID reader and a barcode scanner and pay for their purchases, they have to wait in a long line. The only way to change this is to make smart choices when shopping in malls. Each individual item is tagged with an RFID tag that can be read instantly by a cat with an RFID reader when placed in a smart shopping cart, allowing billing to occur directly from the cart. With this technology, customers can avoid standing in line at checkout counters. In this solution, additional smart shelves are available with an RFID reader that can track inventory and update the main server. This server can be installed and also knows the status of products in a shop. Inventory management is also facilitated by the fact that all goods can be read automatically by an RFID reader instead of being scanned manually by employees.
