NFC

NFC is fast and it's high bandwidth. You can even power like the device. If you want to start putting a bunch of route hints in or a bunch of trampolines or blinded stuff, you can do it's interactive. So if you wanted to put something beefy in there to help the speed and success of the payment, you got to use NFC because yeah, QR code just max out unless you do start doing like animated. There is a reason why that stuff lip-frogged in North America, like the chipping pin and everything else,. Like you guys went straight from like a magnetic to tap. They forced that though.
