Reviewer: Yoav Nir Review result: Has Nits The changes in revision -17 are fine. I would still like to have it stated that financial information is not at risk of leaking because the account information of a customer is only sent in communications with that customer. The Security Considerations section already says that encryption is used when transmitting financial information. That is necessary but not sufficient. You also need to state that such information is only sent to entities that should have access to that information.
