The Cornetto "Series Commitment" rings are NFC-Connected rings, (designed by ice-cream brand Cornetto) to keep unfaithful parners from skipping ahead in TV shows. The rings block access to TV shows you're watching as a couple, unless both of you are nearby. Cornetto calls this the "worst type of cheating." The brand is negotiating with streaming apps to possibly get these rings distributed and going in the near future.
Register here to get first dibs on them, as these are likely to be a pop craze phenom.
