A smart refrigerator, also known as internet refrigerator, is a refrigerator which is able to communicate with the internet.[1] This kind of refrigerator is often equipped to determine itself whenever a food item needs to be replenished.[2] This is still partly managed by human involvement but the next evolution of smart technology is the Intelligent Refrigerator, which incorporates inventory tracking for all items inside, along with a seamless payment system. This involves connecting the refrigerator to an online retail store, ensuring a consistently stocked refrigerator at home for domestic use. For commercial use, additional features such as payment terminals and locks are integrated to manage tasks like unattended retail and queue busting.
