9 things retirees should never keep in their wallets

Passport

If you’re planning a lot of international travel in retirement, note this: A government-issued passport, including a wallet-size passport card, opens up a world of possibilities for a con artist. “Thieves would love to get (hold of) this,” says Nikki Junker, a victim adviser at the Identity Theft Resource Center. A stolen passport or passport card can be used by an identity thief to travel under your name, open unauthorized bank accounts or even get a new copy of your Social Security card.

Instead, keep only your driver’s license or other personal ID in your wallet while traveling inside the United States. When you’re overseas, carry a photocopy your passport and leave the original in a hotel lockbox.
