A crossbody purse with a built in wallet will keep all of your cash and credit cards organized and instantly accessible. That means you can leave your space-hogging regular wallet at home. The zipper of the bag is designed with a snap button to lock another zipper for increased security. At the same time, the part of the built-in wallet with RFID can better protect your personal information from being leaked.
