Comparing smart wallet signing flows to credit cards:

- Normal signing with a passkey: Analogous to paying with Apple Pay in untrusted environments like a ecommerce site or a bodega. 

- Issuing a session key: Analogous to saving your credit card in trusted apps like Amazon where you want to do one-click purchases.

Would need to run it through a regular debit card to work with the trad systems.

A QR code could send you to a web page where you could pay on your phone via passkey.

What about NPC tap to pay with USDC?  Is is possible to integrate that ability into smart wallets?

I didn’t get there by wishing for it or hoping for it, but by working for it❤
