WPF design pattern for "automated" applications (Don't think MVVM is suitable?)

I'm trying to get into WPF and have been reading articles saying MVVM is generally the way to go for WPF.

What about application that doesn't require user interactions such as button clicks?

An example would be a Card reader application:

• User connect card.
• Application read and display card info on screen.
• Perform backend validation.
• Display result on screen.

I could be wrong but I don't see MVVM being suitable for such application. Is there a more suitable design pattern that I should be considering instead?
