Answer:

RFID scanning or Barcode reader

Explanation

Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge. Once you pass your items through the inbuilt RFID scanner in the fridge, the barcode of your items is cross-referenced with a database and given a unique tag for identification. This technology helps detect and track the stock that is inside your fridge and when you start running low, the RFID can be triggered to send a reminder as a notification on your email or a text message.

How can photography allow us to view the world around us in different ways?
Ymorist [56]
It captures a single moment that one might not see with a naked eye. It shows the beauty and the essence of simple things in one exact moment. And it allows the viewer to take more time to reflect on what is captured and really find meaning within it.
