Some restaurants here in the US print a QR code on the check now. If you've got google pay/apple pay/whatever you can just scan it and immediately pay, then leave. There's also a few where you don't even need a server to order, you scan a code on the menu and can order whatever, a server delivers it, then you pay whenever and leave. It makes it really convenient when you go in with a bigger group. No worries about splitting bills, making sure everyone is ready to order, etc. Everyone can just order what they want, when they want, and all pay and leave when they want.

Is a tip still expected in that case?

A fuck-you solution would be - QR code includes tip, but you can wait for waiter if you don't wanna tip (or wanna tip more)
