I can understand your point of view. For now the ring is not built to work like that; it works on the finger. But you bring an interesting conundrum and I think that we can add this as an optional for people to decide whether they want to left their rings unlocked or lock them. I still don't understand how the tangem ring would *know* it's not on your finger unless you have an actual information being transmitted, i.e. locking the ring, but we can probably implement a locking mechanism that you can activate from within the app. I'm not 100% sure if we will be able to include this in the absolute first release but I'll have a deeper look at it.
It's just antenna placement and shielding for the NFC. If you get it *just* right you can get it to scan while on your finger. But there is no way you can do it easily. Not so much tech as design.
