Multi-Card - Low Fidelity Mockups

So the project is a kickoff on how our web servicing platform in the UK will look to service customers with more than one card. For example, a Capital One & partner card. At present we have separate logins for such a setup, so the customer is reliant on moving in and out of the product to service multiple cards... not ideal! With this new solution, we're looking at different methods to treat this as well as some early ideas for interaction patterns. The one you see above is simply, login > add a new card > sidebar detail input > added to account and user can switch between accounts to service.

The ideal solution would be to add cards up front in the on-boarding session and the cards be there to service from the off, but the process of adding an additional card will always need to be considered should they apply at a further date. Some further options can be found in the PDF, but any feedback or ideas are warmly welcomed!
