I have been trying to got to a "leaner" wallet in the front pocket and banish the fat "butt" wallet.  With many things now on the ol' smartphone there is less reason to carry so many cards.  With a little bit of effort, I got down my carry wallet to this minimalist thin profile in this wallet.  I don't know what the real risk of "Hacking your chip cards" and such in your wallet but this wallet says it blocks that too.  Great minimalist wallet if you are trying to ween yourself form a "fat butt wallet" profile.
