This ring is incapable of being used for credit card payments or electronic locks. Its only function is as a ring, and the accompanying app is not helpful, only allowing you to block certain phone features like the gallery. I have tried to find a practical use for it for a couple of weeks with no success. Therefore, I do not recommend it.

This item and the seller are very good.

This is not what I anticipated.

This is a popular item! I wish you success!
