Abstract: Device with RFID radio frequency identification window that couples to the mouth of a shopping cart, or another container, that includes a frame with a window horizontally crossed by a plurality of light rays coming from a light curtain, an infrared sensor configured to detect an object that approaches the window, an RFID reader configured to detect and identify codes contained in RFID labels incorporated in the objects that enter or exit the basket of the cart through the window, UHF antennas, the radiation beams of which cover the space of the window, configured to be activated once the infrared sensor detects the object that approaches; and a processor configured to store the objects that stay inside the cart in an electronic shopping list.
