This slim, compact wallet can be used in a small cross body purse that is placed inside a bag under an airplane seat.  When the wallet is opened, there's a separate compartment for bills, several places for credit cards and id, plus a small zippered pocket for coins on the back. Folded, it fits neatly along half the length of the purse.  Carries necessities, saving space for air travel.  I took driver's license, insurance cards, two credit cards and some cash.  Left the shoppers' cards, library cards and business cards at home.
