One of the nice security features of the Tangem ring is that fact that it will not work while on your finger. So you don't have to worry about people communicating with it while it's on your hand. Or just grabbing your phone while you sleep and and putting it to your hand, you actually have to take the ring off.
IMO having it work while on your hand is not a good idea.

Does that not defeat the purpose of having a wearable hardware wallet if you have to take it off? RingWallet will also support card payments at some point in the future, making it easy to pay with it at any POS in the world - directly from your finger, and directly using self-custody crypto.
Once again IMO, it's a security thing. You have to preform the deliberate action of taking the ring off to use it. People can't say grab your phone while you are sleeping and then use a fingerprint to unlock it and do something with the ring. You could probably get my phone and finger while I sleep but there is no way you are getting a ring off without waking me up. That is obviously a worst case scenario.
Or how about you are doing a TX but since the ring is on the finger of the hand that you are using to hold the phone a TX is sent before you are 100% ready. Having to take the ring off is just a security thing.
Kind of like Tangem cards. Mine never leave their rfid shields until I am ready to do something.
Everyone has a different view. This is just mine.
