+Thanks for the video! It's always good to see these things in action so

+
+Supporting Bluetooth is optional in the sense that if a wallet should
+not support it, you will still receive the transaction via the P2P
+network. So I'd say definately go for Bluetooth.

+
+I wonder about the receipt step -- are you generating a PDF on device
+and sending it via NFC? This is something that could be supported by the
+BIP70 payment protocol. We should try to avoid the second tap, its not
+intuitive.

+Contactless cards? Last I was to London, the Oyster card was already
