"You can build your own thing using card emulation via apps, but you will take all the risks." right! This is exactly what I've developed. I've built a new NFC application, with its own PKI infrastructure, that's deployed onto users' mobile devices via an app install. It works over APDU, but it would be more efficient if A1 was made available by the two major mobile OS. It would likely shave off >10% of the total time to complete which makes a material difference to the failure rate (ie. customer's lifting away too early or other interference) and therefore improves the overall UX.
