"online" payment future in the fiat world

Probably this can be understood by nostr developers here more than pure bitcoin developers. Because passkey is used as "identity by public key", and cooperates between a merchandise site and payment gateway services.
Imagine replacing Passkeys with Nostr and replacing MasterCard with Bitcoin. The 3-layer structure of merchants, payment gateways, and banks would be reduced to at least 2 layers (bank out), or just 1 (only merchants).
From creditcards vs bitcoin to creditcards×passkeys vs bitcoin×nostr
NOTE: This framing may be too simplistic. Other combinations such as Nostr and Passkey, payment gateways and Bitcoin, or passkey and Bitcoin(!) may work together.
