Why do car rental companies prefer/require credit over debit cards?
A hotel can accept the debit card because each night they can withdraw the money. If you don't have sufficient funds they can instantly lock you out of your room. They an also limit your ability to access room service, and other extra expensive options. The rental car can't do that once you have the car. Plus they never know if you will bring the car back with damages, toll charges, and an empty tank of gas. Deposit on a Debit Card have a different effect, and many people don't understand it (and make a big stink), or cannot afford it (or both). Either of it results in lots of trouble for the business: In addition, having a credit card showes that some bank trusts the customer with an unsecured credit of this height, which is some reassurance for the business. A debit card proves only that he was able to get a checking account, which needs much less liquidity and stability. People with credit cards tend to have better credit than those who only have debit cards. People with better credit tend to not abuse such things as car rentals. It costs money for any company to run your credit. It doesn't cost a rental company any outflow of money to reject debit cards. So the possession of a credit card becomes a stand-in for running your credit before you rent a car. I am not sure if this is the actual reason or not, but all of the major credit cards (Visa, Mastercard, Amex, Discover) provide damage insurance coverage on car rentals. Debit cards do not usually provide this coverage. So, if you use a credit card, the car company knows it will be able to recover the cost of any damage to the car.  Of course, this doesn't explain some of the odd debit card policies out there. For example, Alamo will not let you use a debit card unless you provide proof of round trip travel (like a plane or cruise ticket). But you can use a credit card without having a travel ticket. I'm not sure how having a travel ticket makes debit card users less of a risk, but apparently it does somehow. 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. I have looked at the conditions of a car rental company, and I believe it provides the answers: Upon pick up of your vehicle, you must present a valid credit card (*)   used to make the booking and which must be in the driver´s name. If   you do not have a valid credit card we will accept your debit card   when you pick up your vehicle. However, as we cannot reserve credit to   cover the potential damage or refueling costs, you will need to take   SuperCover and a fuel tank of fuel at the start of the rental. We will   refund the value of the unused fuel at the end of the rental unless   otherwise agreed with you. (*) VISA, MasterCard and American Express   are accepted. Credit card or Third Party Insurance IMPORTANT: In case of damage, we   will charge you the incurred amount up to the excess. You will then   need to reclaim this amount from the provider of the credit card or   third party insurer. We strongly recommend that you fully read and   understand the terms and conditions of any cover provided by your   chosen provider before you decline any of our optional services.   Without our SuperCover, should you damage the vehicle during your   rental period, we will charge you the corresponding amount up to the   excess, regardless of whether you can subsequently reclaim this amount   from the provider of the credit card or the third party insurer. In   the event you would like to dispute any of the above mentioned charges   you should send your request by mail or email to the Firefly location   state on your rental agreement. https://global.fireflycarrental.com/qualifications-ES.html From that, we can conclude that : It's likely that disputes with customers in case of damage cost a lot to car rental companies, and for the 2 above reasons, demanding a credit card may alleviate it.
"I worked for a major car rental company (not Hertz, but comparable) for quite a while, taking reservations by phone. I completely agree that the reservation system is terrible, and is only vaguely based on the reality of their vehicles in stock at best. The problem is, from a strictly business perspective, taking more reservations than they have cars is currently considered the most profitable model for them.  To play devil's advocate just a little, switching to a ""take only one reservation per vehicle, reserve it to 100% lock it in"" model is a bit more complicated than it sounds. In order to guarantee a specific car for a customer at a specific time, they either have to leave that car sitting on their lot until you rent it (not making money), or keep renting it out to other people in the interim. If they rent it out to someone else before your rental comes up, that removes the vehicle from their control. Bordering on constantly, renters don't return the vehicle within their promised schedule or return it in a damaged or otherwise unsuitable condition. To be clear I'm not trying to make excuses for the rental car company (there are many reasons I no longer work there), but it's objectively hard for them to get a specific vehicle if, say, all but one of them were in wrecks the previous night, and the person renting the last one drove it across the country without warning the rental office and refuses to come back. Those problems all get solved eventually, but that doesn't help you when you show up and can't get the car you reserved.  So, they continue to take excessive reservations, and just give people whatever they happen to have when they show up, if they have any cars at all.   There's definitely better ways to do it for the customer, but like many businesses, they'll continue to do it whatever way they determine is best for their profits.  Edit: Words." Credit cards are a golden goose for banks, as they get to issue high-interest loans and simultaneously generate alot of fee income. Debit cards aren't quite as good, but they still generate substantial fee income -- ~2% of every credit/non-PIN debit transaction goes to the bank and credit card network. Credit histories exist because they are the most effective tool available to predict whether you will pay back your loans or not. You don't need a credit history to buy most things, you need a credit history to get a large loan. Think of it from perspective of a lender: Credit scoring is the bank's way screening out people who are expensive to do business with. It's objective, doesn't discriminate on the basis of race, sex or other factors, and you have recourse if the rating agencies have incorrect information. "These are two different ways of processing payments. They go through different systems many times, and are treated differently by the banks, credit card issuers and the stores. Merchants pay different fees on transactions paid by debit cards and by credit cards. Debit transactions require PIN, and are deducted from your bank account directly. In order to achieve that, the transaction has to reach the bank in real time, otherwise it will be declined. This means, that the merchant has to have a line of communications open to the relevant processor, that in turn has to be able to connect to the bank and get the authorization - all that while on-line. The bank verifies the PIN, authorizes the transaction, and deducts the amount from your account, while you're still at the counter. Many times these transactions cannot be reversed, and the fraud protections and warranties are different from credit transactions. Credit transactions don't have to go to your card issuer at all. The merchant can accept credit payment without calling anyone, and without getting prior authorizations. Even if the merchant sends the transaction for authorization with its processor, if the processor cannot reach the issuing bank - they can still approve the transaction under certain conditions. This is, however, never true with debit cards (even if used as ""credit""). They're not deducted from your bank account, but accumulated on your credit card account. They're posted there when the actual transaction reaches the card issuer, which may be many days (and even many months) after the transaction took place. Credit transactions can be reversed (in some cases very easily), and enjoy from a higher level of fraud protection. In some countries (and most, if not all, of the EU) fraudulent credit transactions are never the consumer's problem, always the bank's. Not so with debit transactions. Banks may be encouraging you to use debit for several reasons: Merchants will probably prefer credit because: Consumers will probably be better off with credit because:" In Addition to @JoeTaxpayer's answer, in the UK credit cards offer additional protection than if you were to pay by debit card. This includes (but is not limited to) getting your money back if the company you've bought something from goes bust before your order is complete. "You ask about the difference between credit and debit, but that may be because you're missing something important. Regardless of credit/debit, there is value in carrying two different cards associated with two different accounts. The reason is simply that because of loss, fraud, or your own mismanagement, or even the bank's technical error, any card can become unusable for some period of time. Exactly how long depends what happened, but just sending you a new card can easily take more than one business day, which might well be longer than you'd like to go without access to any funds. In that situation you would be glad of a credit card, and you would equally be glad of a second debit card on a separate account. So if your question is ""I have one bank account with one debit card, and the only options I'm willing to contemplate are (a) do nothing or (b) take a credit card as well"", then the answer is yes, take a credit card as well, regardless of the pros or cons of credit vs debit. Even if you only use the credit card in the event that you drop your debit card down a drain. So what you can now consider is the pros and cons of a credit card vs managing an additional bank account -- unless you seriously hate one or more of the cons of credit cards, the credit card is likely to win. My bank has given me a debit card on a cash savings account, which is a little scary, but would cover most emergencies if I didn't have a credit card too. Of course the interest rate is rubbish and I sometimes empty my savings account into a better investment, so I don't use it as backup, but I could. Your final question ""can a merchant know if I give him number of debit or credit card"" is already asked: Can merchants tell the difference between a credit card and embossed debit card? Yes they can, and yes there are a few things you can't (or might prefer not to) do with debit. The same could even be said of Visa vs. Mastercard, leading to the conclusion that if you have a Visa debit you should look for a Mastercard credit. But that seems to be less of an issue as time goes on and almost everywhere in Europe apparently takes both or neither. If you travel a lot outside the EU then you might want to be loaded down with every card under the sun, and three different kinds of cash, but you'd already know that without asking ;-)" I haven't had a credit card in fifteen years. I use nothing but my debit card. (I find the whole idea of credit on a micro scale loathsome.) I have yet to encounter a single problem doing so, other than a lower than usual credit score for not keeping 23(!!!) revolving lines of credit open, or that's the number CreditKarma tells me I need in order to be an optimal consumer. In an nutshell, no, you don't NEED one. There are reasons to have them, but no. Debit cards with the Visa or Mastercard symbol on them work technically everywhere where credit cards work. There are some limitations where the respective business does not accept them, for example car rentals want a credit card for potential extra charges; but most of the time, for day-to-day shopping and dining, debit cards work fine. However, you should read up the potential risks. A credit card gives you some security by buffering incorrect/fraudulent charges from your account, and credit card companies also help you reverse incorrect charges, before you ever have to pay for it. If you use a debit card, it is your money on the line immediately - any incorrect charge, even accidential, takes your money from your account, and it is gone while you work on reversing the charge. Any theft, and your account can be cleaned out, and you will be without money while you go after the thief. Many people consider the debit card risk too high, and don't use them for this reason. However, many people do use them - it is up to you. "A lot of credit card companies these days uses what they call ""daily interest"" where they charge the interest rate for the number of days till you pay off what you spent. This allows them to make more money than the ""period billing"".  The idea of credit, theoretically, is that there isn't really a day when you can borrow without paying interest - in theory" Many small businesses are still cash and check.  For example my landlord does not take credit card or online transfer.   My choices are cash and check, and I prefer checks for the paper trail. How you can pay your rent is really up to your landlord. They are, however, unlikely to take a credit card, for at least two reasons. Firstly they are unlikely to have the means to take electronic payment Second, and more importantly, merchants get charged a percentage of the transaction.  These fees can be quite high to them for premium cards like travel and gold cards; three, four or even five percent of the value of the transaction. This is sometimes why you see cash discounted pricing. I thought this was because credit card companies charge the retailer a fee to accept credit card payments. If you spend $100, the retailer pays $1 (or whatever percentage they have negotiated) to the credit card provider.  Handing over $100 cash and paying $1 fee to Visa means a loss to the retailer. The same transaction on $100 worth of product means the loss is accepted out of the profit margin which the retailer accepts to attract custom. Here's one reason that's being overlooked in answers so far. (@ChrisInEdmonton, this is for your comment on @Chad's answer.) How do credit card companies make money? Sure, there's interest charges, but those are offset significantly by the cost of borrowing money, and by people defaulting on their debt / entering bankruptcy. The other way they make money is by processing transactions. They get a cut of whatever you buy. If you're a high-income person, and you're going to process a lot of expenditures with this credit card, your business is worth more. They will be willing to bribe you with things like cash-back, frequent flier miles, and insurance on your auto rentals, so that they can be your #1 go-to card.  (This works in concert with the way that some credit card vendors with richer clientele overall - American Express - get to charge higher merchant fees for access to these customers' wallets. But that was mentioned in other answers.) If you're not a high-income person, your business is worth less. If you go somewhere asking for credit, they're going to try and give you a card which will earn them the most money - which probably isn't the one where they give you back 50% of their transaction fee in rewards. It's a calculated risk, since they still have to compete against cash, debit cards, and all the other credit card companies, so they don't have you totally over a barrel, but you shouldn't expect as many freebies, either. My bank charges me on my statement for debit transactions, but rewards me with bogo points when I run transactions as credit. AFAIK, retailers are prevented by contract with VISA et all from recouping the merchant fee from you (instead they can mark up all prices and offer a 'cash discount'), not that you'll be able to convince your vietnamese grocer of this. The difference between debit and credit fees is large enough that even these small tricks by the bank can mean a lot of money for them. Since most retailers accept either, they recruit me into their profit game with carrots and sticks.  I've since moved to an actual cash back credit card and haven't regretted it yet. Credit in debit way - the card simply functions like a debit card for that transaction - pulling cash from your checking account. No difference.  You've simply discovered the fact that some banks are using the same piece of plastic for two functions, debit which draws funds directly from your checking, and credit which offers you time to pay a bill the comes in some time later. It's a personal choice. In Canada, there are many stores that take debit (Interac) but don't take Visa or MasterCard. For example, a corner store. In the US the reverse is often true: every tiny place seems to take Visa or MasterCard, but not debit. A Visa debit card looks like a Visa card to the merchant. It therefore has the benefit of being usable at places that only take Visa. (Substitute MasterCard as necessary.) This benefit is very small in Canada, less so elsewhere. Meanwhile the money is actually coming out of your bank account just like a debit card, which therefore has the benefit that you're not borrowing money, can't accidentally overspend, and run no risk of incurring interest charges. It is also a way to get what appears to be a credit card when you can't qualify for credit. If you do the majority of your spending in Canada, you don't need a Visa or MasterCard debit card. Your regular debit card (Interac) will work fine for you. If you have a credit card anyway (from another bank or whatever) then again, you don't need a debit card that can pretend to be a credit card.
