I don't have a lot of experience with NFC, but there are replay attacks of NFC-based credit cards, e.g., the NFCProxy app discussed a few months ago[1]. Does the small size of the inlay in this ring prevent unintended reading of the information contained? (It sounds like a larger version is necessary for some phones to read it at all...) This is a compelling idea for another authentication factor, provided there were no concerns about data leakage.
