Carry my wallet in my front pocket. Be pretty hard to slip the billfold out and not be noticed.
My wife and I were at the airport in San Juan for a few hours. She had a Visa card in her wallet which she never uses and is only kept for emergencies. The card was never used at the airport, or even taken out of her purse, and she never lost possession of the card. When we got home a few weeks later, all these charges from around San Juan and Puerto Rico started to show up on her card. The only thing we can imagine is that some thief used an RFID scanner her purse at the airport.

A rat trap in the back pocket might be fun. Just remember to keep your own hands out and not to sit down!
my wallet is in left front cargo pocket because my GLOCK is IWB 4 o’clock.
