Auto-logout from the kiosk

People forget to logout from the kiosk. Auto-logout should be implemented. An optional addition to this would be to automatically logout the user, but save the cart for later approval by the customer.

Maybe this could be nicely integrated with Pending transactions? For whenever a cart should be kept for later approval. Would the backend be ready for achieving that at this moment, or is there more changes needed before it can be applied?

I think it would work nicely!

Things you need to do is basically a way of creating pending purchases and approving them. The wallet module needs to be extended with ability to approve pending transactions. It is basically the same for product transactions. Then, you would need an endpoint for retrieving a purchase and its content. It may collide with Hampus's work though.
