I use Catima and I am happy with it but it doesn't have the feature to crop images and use it as a logo. It's easy enough to image search logos though.

I might give this a try. I use Google Wallet for my various loyalty cards and whatnot, but it is actually a poor UI for it, mixing credit cards and loyalty cards in a single sideway sliding interface that takes forever to find what you want.

Unfortunately I can't use the app for my public transport ticket because it doesn't support .pkpass files.
