Thanks for Alan's summary.

For the" Part 2: Security and data protection for mobile financial
services"I have some consideration that in order to protect financial
privacy useful, the mobile device technology should combines Secure Elements
(SE) and a Trusted Execution Environment (TEE) to protect payment
credentials. Beacause the SE only has Limited processing and storage
capacity, but TEE can offer safe execution of authorized security software,
known as 'trusted applications', enables it to provide end-to-end security
by enforcing protection, confidentiality, integrity and data access rights. 

And when we design the payment architecure and use cases, we should also pay
attention to that some payment application should be served as a TA(trusted
appliation) to run in the TEE for security.

For example in the Use case  "6.2.3.1 Non-essential Use Cases -Biometric",
we have already emphasized as following:
An individual's privacy should be protected when performing any sort of
biometric authentication.
Important data, such as the fingerprint template and private key, and
sensitive code should be stored and executed in a Trusted Execution
Environment (TEE).

: Paper on Summary of ISO12812 by Alan Thiemann

Dear Web Payments group:

My colleague Alan Thiemann[1] has written a summary of ISO 12812[2].  This
work is Alan's opinion of the work - not official.  But it is a very good
introduction to the work and the expected trajectory at ISO.

I would request that everyone in our group give this paper consideration -
it won't take long, and will help inform any needed discussion.

Best regards,
David
