# Smart refrigerator

A smart refrigerator is a refrigerator that is able to communicate with the internet. This kind of refrigerator is often designed to automatically determine when particular food items need to be replenished.
This functionality is partly managed by human involvement, but proposed future iterations of the technology incorporate inventory tracking for all items inside, along with a seamless payment system. This capability would involve 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 could be incorporated to manage tasks like unattended retail.

## History

By the late 1990s and the early 2000s, the idea of connecting home appliances to the Internet (Internet of Things) had been popularized and was seen as the "next big thing". The proposed idea of a smart fridge that could keep track of its contents with "a bar-code reader within the fridge" had become popular in various technology newspapers. In June 2000, LG launched the first internet refrigerator, the Internet Digital DIOS. This refrigerator was unsuccessful because consumers saw it as unnecessary and, at over $20,000, too expensive.<

## Controversy
### Security

In 2000, Russian anti-virus company Kaspersky Lab warned that in a few years Internet-connected refrigerators and other household appliances might be targets of net viruses or trojans in a publication: Internet Security: Emerging Threats and Challenges (Adamov, Alexander; A, Milan). Examples included attacks that could make the refrigerator door swing open in the middle of the night. In January 2014, the California security firm Proofpoint, Inc. announced that it had discovered a large "botnet" which infected an internet-connected refrigerator, as well as other home appliances, and then delivered more than 750,000 malicious emails. In August 2015, security company Pen Test Partners discovered a vulnerability in the internet-connected refrigerator Samsung model RF28HMELBSR that could be exploited to steal Gmail users' login credentials.

### Support

In late 2014, several owners of Internet-connected Samsung refrigerators complained that they could not log into their Google Calendar accounts, after Google had discontinued the calendar API earlier in the year and Samsung failed to push a software update for the refrigerator.

In season 4 finale, "Server Error", thanks to his hacking, Pied Piper's plan for the new Internet is proven by the 30,000 smart refrigerators connected together that create the new Internet, as he hacked using some of their code, replacing his dead server, Anton, who backed itself up to the smart refrigerator before it died.
