Really cool concept but the potentials of attacks against people that are wearing these type of jewelry is definitely concerning, maybe if there's a way to customize the ring so it's totally not easily seen as something identifiable to be your product might be a big help, what I mean is that people should be able to add modifications to it that would make it look like any other ring on someone's finger, the lack of customization in my opinion is a security flaw because as what RickDecard, once it becomes a mainstream thing, scammers and people that have ill intentions will definitely try to do something about it once they recognize the ring.
