This wallet is a little large than my old one but that is not a problem.  Can't say how well the RFID works as I have no way of testing it.  I like the divider in the bill section as I can keep larger bills in one section and the smaller bills in another.  There is plenty of room fr credit cards and I like the fact that the slots are a little bigger making it easy to insert and remove the cards. All the wallets I've had in the past the CC slots were too narrow making it difficult to insert cards.  I would purchase this item again.
Update: I recently stayed in a motel where the door "key" was an RFID type of entry card.  You just held the card up to the door lock and it opened.  I tested this wallet for the RFID by trying to open the door with the card in the wallet and the lock would not open.  A friend tried the same test with his wallet and the card would unlock the door while the card was in his wallet.
