We can all be guilty of packing our wallets with things we don't really need. Here are 6 things to keep in your wallet from Yahoo! Finance.
1. Basic Contact Information. It's best to include your phone number where it's easily visible. While you're at it, make sure to include some emergency contact information as well, whether it's the phone number of a spouse or roommate.
2. Business Cards. You may want to keep some business cards in your wallet, because you never know who you might meet. Better yet, save the wallet space and go digital. Apps like Beam-Me, Snap-Dat and Drop-Card make exchanging information easy.
3. Cash. You may think it's passé to carry cash these days when you can make nearly any purchase with your bank card or smartphone. But consider that 25 to 50-dollars is enough to split a restaurant bill with a friend, and cash always comes in handy in an emergency.
4. Government I-D. Don't forget your driver's license. If you need to keep rewards cards handy, try slimming down with services like Passbook -- a new iPhone feature that lets you access reward card information, boarding passes, tickets and even coupons from your phone.
5. Plastic. Debit or credit cards help with everyday transactions, but if you have more than a few, you may want to place the ones you use more frequently near the front. For example, your low-interest credit card or rewards card -- and leave the extras in a safe place at home.
6. Insurance Cards. Next, carry your dental, vision and health care cards in your wallet whenever going to the doctor, and especially keep you primary care card on you at all times in case you have go to the hospital in the event of an emergency. However, be aware that Medicare cards still display social security numbers, so experts recommend using a photocopy and blocking the digits except the final four.
