@npub1ds3h...hzcn how will this work for me as a customer if i wish to pay in bitcoin? will i have to tell the merchant i want to pay with bitcoin, in similar fashion how they now ask me cash or card? how do i get the bitcoin qr code to show up so that i can scan it?

Curious as well. Currently there is a qr code fir cash app. I imagine it will just be an ln invoice qr code payable by any ln wallet.

It's a QR code. If you have the cash app, you can also accept payments with yourusername@cash.app. At least some people can. I'm mot sure why it doesn't always work. They're probably still testing.
