Of course, it's great that it's compatible with existing systems. It'd be nice if the part that's making payment is disconnected from my phone so I wouldn't have to hand over my phone to someone else. A potential short term solution would be to allow me to lock my phone with a pin and still have this work. A lot of merchants want to see the physical card when making payment. I'd imagine many would be skeptical of something like this. It's really nice to see all these ideas trying to crack the payment code. Keep at it!!
