Most car rental companies in Boise require a credit card for renting a car. This is because the credit card provides a form of security deposit and allows for payment of any additional charges or damages. However, some rental companies may accept debit cards or cash deposits, but they may have stricter requirements and restrictions. It's best to check with the specific rental company for their payment options.

To rent a car in Boise, you will typically need the following documents:

• Proof of insurance: Some rental companies may require proof of insurance, either through your own policy or by purchasing insurance from them.
• Additional identification: This may include a passport or other form of government-issued identification.

It's important to check with the specific rental company for their document requirements as they may vary.
