Thought I'd attend the annual defcon (hacker convention) in Vegas this year for the first time and needing one of these wallets was the first thing that came to mind. Thought it amusing that they only take cash, no checks/credit cards at this convention (these are hackers afterall):) It did occur to me I could just leave my credit cards at home but I don't like carrying around wads of cash.

Like others have said, the pockets for your cards are very snug. Not a chance they will ever fall out by accident. Not sure if that is by design or lack of double checking measurements (measure twice, cut once). Not a bad looking wallet overall. Time will tell how well it holds up. From what others have said it does give you rfid protection.
