Why do car rental companies prefer/require credit over debit cards?
A few reasons make sense: They have a defined process for rentals, risk assessment, and customer credit. Especially for a large corporation, making changes to that process is not trivial, adds risk/uncertainty, and will be costly. Such changes for a relatively small customer base might not makes sense. Many rental companies DO allow you to rent with a debit card. Why do some businesses take cash only?  With a debit card, there is no third party guarantee. With a credit card, the cash is coming from a well-established third party who will pay (assuming no disputes) and has a well-established history of paying. Even if the merchant holds your account, it is still your cash under the control of you and your bank until the deposit clears the merchants bank. It is not surprising they view that as more risk and potentially not worth hassling with debit.
