A Hub transmits all data received to all network devices connected to it, regardless of which device the data exists being sent to.
<h3>What is Hub?</h3>
A hub stands for the connection point in a computer device where data from numerous directions converge and are then sent out in many directions to respective devices. A hub may even act as a switch by preventing distinct data packets from proceeding to a destination. There exist three types of network hubs: passive, active, and intelligent.
A network hub exists as a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub stands less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices. Network hubs stand best suited for small, simple local area network (LAN) environments.
Hence, A Hub transmits all data received to all network devices connected to it, regardless of which device the data exists being sent to.

Answer:
RFID scanning or Barcode reader
Explanation
Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge.
