How a Smart Cooler Detects Taken Items – Scales, RFID, Cameras

1 min read

In a smart cooler, customers take items themselves. The device needs to know what they took. Here are the technologies that make it possible.

A smart cooler first authorizes a payment, for example by card, then unlocks the door, and after it closes works out which items were taken and charges only for those. Recognition uses shelf scales, RFID tags, or cameras with software, depending on the model.

Step by step
