This is a good wallet that is perfect for the front pocket of a sport coat or front pocket of your pants that won't show a bulge.  I can put my drivers license, two other cards, and some pocket money in here without it gapping out like a regular billfold.  I will assume the RFID feature works as (a) I have no way to test it, and (b) I haven't been hit with a lot of fraudulent charges since using it.  At just $11 here on Amazon, I thought this was a very good deal.
