Where I work, customers are required to show their photo ID. Many people have difficulty getting their license out of their cluttered wallets, but one customer did a very clever thing. She stuck a piece of Scotch tape to one side of her license with the majority of the tape hanging off the edge. She folded it over onto itself to create a tab. Then she just pulled on the tab and her license slid right out of her wallet. I have shown this to many people and they are amazed at how much easier it is for them, myself included.
And, if you want to create more than one tab, you can color them with sharpie so you know which one is which when tabbing through. Susan
