I've been using the SUPCASE from amazon since May, almost all of that time spent traveling in Europe and the US. It doesn't look $$$ but performs well. I keep ID and a credit card in the slots, cash in the front flap. The magic on/off function works with the flap. Magnetic catch work well. It even works with my wireless charger.
For $15 I am very happy and probably will not go back to my Spigen case when I get home in August. Not only does this replace my wallet, but it also protects the screen when I carry the phone or toss it in a bag. The "leather" case also looks like a small notebook, so it is less obvious perhaps in a shirt pocket.
