I definitely prefer a bifold over a trifold. I missed having coins handy so I decided to try one with a coin pouch in it. I'm very satisfied with it. This is the layout and the maker, although I don't remember the RFID blocking feature when I bought it. In general, I put it in the back pocket of jeans and the front pocket of shorts.
