What does everyone need to fit into a wallet? In mine for example, (standard tri-fold wallet)

1 - @ 11 "cards" (credit cards, atm card, library card, kroger card, scuba card, sears craftsman card,....)

2 - Photo holder

3 - Dollar Bill pocket

4 - Business cards


I carry change in a squeeze purse or when in pants, in my pocket. Is it important to have the change purse attached to the wallet?

What other items are we carrying in a wallet? and what features would be needed?
