I can corroborate everything that CanadianSpruce has said regarding EMV vs. MSD contactless payments etc. from my own work experience.
Visa wants MSD contactless to die. Plain and simple. They are slowly updating their rules to limit its use (it will be gone for good in Europe by October 2018). In Canada, since 98-99% of Visa-accepting contactless terminals accept EMV mode (called qVSDC by Visa), not supporting it in mobile devices is a step in that direction. The only contactless terminals I have really seen here that do not support qVSDC are gas pumps (Petro-Canada mainly), some vending machines, and some parking meters.
Here is a reference to this in Visa's operating rules: https://usa.visa.com/dam/VCOM/download/ ... public.pdf
Bottom of page 172/top of 173, last row of Table 4-19. Effective for Canada as of 31 December 2015, support for MSD:
For a a Contactless Payment Device that is not a Visa Card, not permitted for tokenized Transactions.
Since Apple and Android Pay use tokenisation, MSD is not permitted. It is still allowed (but not required) to be supported on physical cards.
