Are Credit Cards a service to banks?
"As i see it, with a debit card, they   are taken kinda out of the game. They   are not lending money, it seems really   bad for them. Not exactly. It is true that they're not lending money, but they charge a hefty commission from the retailers for each swipe which is pure profit with almost no risk. One of the proposals considered (or maybe approved already, don't know) in Congress is to cap that hefty commission, which will really make the debit cards merely a service for the checking account holder, rather than a profit maker for the bank. On the other hand, it's   definitely good for individuals. I disagree with that. Debit cards are easier to use than checks, but they provide much less protection than credit cards. Here's what I had to say on this a while ago, and seems like the community agrees. But, why do we really need a credit   history to buy some of the more   expensive stuff Because the system is broken. It rewards people in debt by giving them more opportunities to get into even more debts, while people who owe nothing to noone cannot get a credit when they do need one. With the current system the potential creditor can only asses the risk of someone who has debt already, they have no way of assessing risks of someone with no debts. To me, all this credit card system   seems like an awfully nice way to make   loads of money, backed by governments   as well. Well, credit cards have nothing to do with it. It's the credit scores system that is broken. If we replace the ""card"" with ""score"" in your question - then yes, you're thinking correctly. That of course is true for the US, in other countries I have no knowledge on how the creditors assess the risks." 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.
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. Michael Pryor's answer is accurate to the actual question asked. The current accepted answer from Dheer is not entirely true but roughly provides an overview of the different entities involved in a typical transaction, with some wrong terminologies, corrected and improved below.  The issuing bank, the one that issues the credit card to the customer. When it comes to the service fee split, the issuer bank takes on the majority of the cut in the service fee paid by the merchant to the different entities. For example, on a 2.5% overall fee paid by merchant, roughly 1.5% goes to the issuer, 0.3% goes to the card network (visa, master card, etc) and the remaining 0.7% goes to the acquiring bank. Reward programs have a partnership with participating merchants, where merchants are charged a higher service fee, for the likelihood of driving a higher volume of transactions to the merchant. A portion of the rewards also comes from the issuer, who shares a percentage of their fee back to the customer, in exchange for the same likelihood of making more profit through increased volume in total transactions. For example, a reward program may charge merchants 4.5% fee, with 3.5% of it going to the issuer. Upto 3% of this can be given back to the customer for their loyalty in using the card service. The banks can afford to take as little as 0.5% instead of their regular 1.5% due to the increased volume of transactions and the fixed fee they collect as membership fee. Note that costco has a similar business plan, but they make money entirely of membership fee. So with enough clients, banks can theoretically afford to run their program entirely on membership fees, costing no additional service fee to merchants. The service fee depicted above is arbitrary, and it can be lowered if the merchant is also a client of the issuing bank, that is, both the issuing bank and acquiring bank are the same. So it is kind of a win-win-win situation. And as usual, the banks can afford to make a larger income, if the customer ends up paying interest for their credit - although the rewards program is not designed accounting on this. Not for normal banking. You can open as many accounts as you want. I did this recently with some Amazon gift card churning for a Chase cash bonus.      Staying a long time may have their credit department reach out and offer you a long time customer discount. But no one is saying you have to close one account to open another. Visa and Mastercard are not consumer-oriented companies. They do not consider individual consumers as their direct clients, and do not sell directly to them. Instead, their clients are financial institutions who participate in their networks (which is what they're selling). The institutions target the individual consumers (merchants and credit card holders). American Express, for example, has a different business model. AX doesn't only sell network services to financial institutions, but also services to individual consumers. You can get a AX credit card/merchant account directly with AX, or through their client bank. The statement in Wikipedia is generic. Whether a particular Bank would charge as per above example or not would be in the card holder's agreement.   So if you do not have any dues, and on 10th April you charge $1000, and on 13th April you charge $500. Statement date is 18th April. Grace Period to pay is say 10th May.   If you do not pay in full by 10th May, and say you only pay $500, Bank would charge interest from 19th April to 10th May for $1500, post 10th may they would charge interest for $1000 balance. Further all fresh purchases would be charged interest from day 1. Net Net Morale of the story is do not carry / revolve money on Credit Card. For all practial purposes use a credit card as a convenience card. I guess it depends on your bank. My bank (Rabobank) recently did introduce this feature. You don't get a card per category, though. Instead you set up rules to match each expenditure to one of the existing pots. No. PayPal payments are credited to a PayPal account. PayPal doesn't let you pay arbitrary banks or credit cards, that defeats the purpose of PayPal and there are other services which can do that cheaper or with less hassle. You need to find another mutually available and satisfactory option with your client. Three big ones that are common in almost all banks (though, individually, they may have other criteria): Other criteria I've seen (while working in the banking industry - varying by bank): the average balance you keep on deposit accounts (checking/savings/CDs/etc), number of overdraft fees in the past 12 months (one bank I worked for wouldn't approve a credit card if a customer had more than 5 overdrafts in the past year), the length of time a customer had been with the bank. Note that a credit card only company, like AmEx, may have different criteria in that they don't offer all the other type of accounts that other other banks do. "American Express is great for this use case -- they have two user roles ""Account Agent"" and ""Account Manager"" which allow you to designate logins to review your account details or act on your behalf to pay bills or request service. This scheme is designed for exactly what you are doing and offers you more security and less hassle. More details here." "There are two things I can think of that might be different in other countries: Until 2013, American Express, Visa and MasterCard prevented businesses from charging extra for credit card usage, and credit card surcharges still illegal in several states. Since credit card companies add a surcharge to credit card purchases, and merchants can't pass that onto credit card users, they just make everyone pay extra instead. Since everyone gets charged the credit card surcharge, you might as well use a credit card and recoup some of that via ""rewards"" points. Almost all credit cards here have grace periods, where you won't be charged interest if you pay back your loans in full within some period of time (at least 21 days). This makes credit cards attractive to people who don't need a loan, but like the convenience that credit cards provide (not carrying cash, extra insurance, better fraud protection). Apparently grace periods aren't required by law here, so this might be common in other countries as well." Credits are expensive, so it's a great advantage to pay in cash. Obviously, it's even more an advantage to pay in cash for a house or a car, of course if you can afford it. But, as annoying as it could be, there are some services, where you're out of option to pay in cash, or even to pay by bank transfer. One of the most prominent examples, Google Play (OK, as I've learned, there are prepaid cards. But Groundspeak, for example, has none.). With the further expansion of Internet and E-Economy there will be more cases like that, where paying in cash is no more an option. Booking of hotels or hostels is already mentioned. There are some that provide no other booking option that giving your credit card number. However, even if the do, for example bank transfer of, say, 20% as reservation fee, please note that international money transfer can be very expensive, and credit card is usually given only for security in case you don't come, and if you do come and pay in cash, no money is taken = no expensive fee for international money transfer and/or disadvantaging currency exchange rate. Exactly.  Or if you prefer, they were not acting *as* banks when doing so.  (Well, at least by the definition I gave, obviously.  If you prefer a different definition, you get a different answer.  Although I'm not sure there really is a useful definition of banking that would cover the behaviour you described.) Think about the credit card business model... they have two revenue generators: interest and fees from borrowers and commissions and fees to merchants. The key to a successful credit card is to both sign up lots of borrowers AND lots of merchants. Credit card fortunes have improved dramatically since the 1990's when formerly off-limits merchants like grocery stores began to accept cards. So when a credit card lets you just pull cash out of any ATM, there are a few costs they need to account for when pricing the cost for such a service: Credit card banks have managed to make cash advances both a profit center and a self-serving perk. Knowing that you can always draw upon your credit line for an emergency when cash is necessary makes you less likely to actually carry cash and more likely to just rely on your credit card. "Yes! Banks, Insurance companies, and other ""financial"" service companies do not contribute anything to the economy.  They are mostly a burden and added costs on those who earn money by MAKING things and adding value to existing things, from manufacturers, to transportation, retailers, services, etc." 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.
