The 'Commitment Rings' by Cornetto, an ice cream company, prevent your partner from watching TV series that you've planned to watch as a couple when you're not around.
The rings work by using Near Field Communication technology, or NFC, which connects to an app that allows shows to be unlocked only when you two are in the same room. When the app senses that you and your partner aren't nearby, it make the programs that you've registered to watch together inaccessible. The Commitment Rings work with popular streaming services such as Netflix, Hulu, Amazon and more. The commercial for the rings shows couples fight over the other carrying on in a series without them, which the company refers to as "the worst kind of cheating."
