While I haven't tested out whether or not this does block RFID reading, I've been using this for about a year and it has held up really well under daily use. My only complaint, and why I didn't give it 5 stars, is that my credit card sticks to the leather when I try to pull it out. It has gotten less sticky over time, but it's still annoying sometimes. No fraying, no tears or holes, and all corners are still intact.
