There are two kinds of money belts for travelers.
The first kind of travel money belt is actually a money pouch, worn under your clothes. While these money belts can be slightly bulky and none too comfortable, they’ll hold everything from your passport to plane tickets—perfect for transport and other times when it’s smart to keep your passport close.
The other type of travel money belt is an actual belt, boasting a hidden, zippered compartment on the side worn against your body. While these are as comfortable as a normal belt and very secure, they can’t hold your passport or credit cards.
