On behalf of Alan Thiemann:


David, Nick,

To be clear, ISO 12812 in the DIS documents, fully supports HCE.   However, in order to provide sufficient transaction security, the Mobile Financial Service Provider must use apps that contain a secure environment, examples of which in Part 2 are: 1) supplemental software controls; 2) a Secure Element; or 3) a Trusted Execution Environment; an app handling the HCE may be resident in the mobile device or in a secure remote server -- either one may deliver the authorization message following the HCE request.  The standard purposely specifies a security requirement but does NOT dictate how an implementer meets that requirement.

I hope this helps explain what is going on for this point.
