Wow this is super cool, but I feel like there is a chance that a fraudulent merchant could display a lower transaction amount on their terminal than what they actually intend to charge, how does this ring mitigate a potential risk if there is not a screen to verify the transaction before signing? Are there any built-in safeguards or secondary confirmation methods to ensure the user is only charged the amount they've agreed to?

I suppose they could cap the transaction amount to just a few thousand sats. Meaning it is just designed for micro transactions, in that case it cool and stress free ⚡️
