Pay online: credit card or debit card?
Credit card, without a doubt. The reason is dispute resolution. If you dispute a charge on debit card - the money has left your account already, and if the dispute was accepted - you'll get it back. If. Eventually. In the mean time your overdraft will be missing $$$. For credit cards, you can catch a fraud action before the money actually leaves your pocket and dispute it then. In this case the charge is set aside, and you will only be required to actually pay if the dispute is rejected. I.e.: The money stays in your pocket, until the business proves that the charge is legit. In both cases, if the dispute is justified (i.e.: there was indeed a fraud) neither you nor the bank will lose money at the bottom line, it's just who's got the money during the dispute resolution process (which may be lengthy) that matters. "I completely agree with @littleadv in favor of using the credit card and dispute resolution process, but I believe there are more important details here related to consumer protection. Since 1968, US citizens are protected from credit card fraud, limiting the out-of-pocket loss to $50 if your card is lost, stolen, or otherwise used without your permission. That means the bank can't make you pay more than $50 if you report unauthorized activity--and, nicely, many credit cards these days go ahead and waive the $50 too, so you might not have to pay anything (other than the necessary time and phone calls). Of course, many banks offer a $50 cap or no fees at all for fraudulent charges--my bank once happily resolved some bad charges for me at no loss to me--but banks are under no obligation to shield debit card customers from fraud. If you read the fine print on your debit card account agreement you may find some vague promises to resolve your dispute, but probably nothing saying you cannot be held liable (the bank is not going to lose money on you if they are unable to reverse the charges!). Now a personal story: I once had my credit card used to buy $3,000 in stereo equipment, at a store I had never heard of in a state I have never visited. The bank notified me of the surprising charges, and I was immediately able to begin the fraud report--but it took months of calls before the case was accepted and the charges reversed. So, yes, there was no money out of my pocket, but I was completely unable to use the credit card, and every month they kept on piling on more finance fees and late-payment charges and such, and I would have to call them again and explain again that the charges were disputed... Finally, after about 8 months in total, they accepted the fraud report and reversed all the charges. Lastly, I want to mention one more important tool for preventing or limiting loss from online purchases: ""disposable"", one-time-use credit card numbers. At least a few credit card providers (Citibank, Bank of America, Discover) offer you the option, on their websites, to generate a credit card number that charges your account, but under the limits you specify, including a maximum amount and expiration date. With one of these disposable numbers, you can pay for a single purchase and be confident that, even if the number were stolen in-transit or the merchant a fraud, they don't have your actual credit card number, and they can never charge you again. I have not yet seen this option for debit card customers, but there must be some banks that offer it, since it saves them a lot of time and trouble in pursuing defrauders. So, in short: If you pay with a credit card number you will not ever have to pay more than $50 for fraudulent charges. Even better, you may be able to use a disposable/one-time-use credit card number to further limit the chances that your credit is misused. Here's to happy--and safe--consumering!" One more thing to favor the card. Extended warranty, or damage coverage. An iPad, if dropped on a hard surface, stands a good chance of breaking. Apple isn't going to cover that, as it's not a defect. Many credit cards offer free coverage for breakage of this type as well as doubling the warranty up to a year. This second year of coverage is worth about 10% of the item cost.  To be clear, I'm talking about running the expense through a card and paying in full, some call it credit no different than those who carry a balance month to month and pay 18% interest. I believe if I have the money to spend on an item, and use the card to get that coverage along with the benefits others posted, it's a convenience, nothing more. Some people who use certain budgeting methods like to set up a payment each week so the bill comes in close to zero. Whatever works. I use another solution: debit card with an account kept empty most of the time and another account in the same bank without any card. I keep the money on the second card-less account, and when I want to buy something, I instantly transfer the appropriate amount to the account with the card and pay. That way money is on the account tied to a debit card only for a minute before payment, and normally it is empty - so even if someone would try to fraudulently use my card number - I don't care - the transaction will be rejected. I think its the perfect solution - no fraud possible, and I don't have to worry about possibly having to bother calling my bank and requesting a chargeback, which is stressful and a waste of time and harmful to peace of mind (what if they refuse the chargeback)? I prefer to spend a minute before each transaction to transfer the money between the two accounts, and that time is not a waste, because I use it to reconsider the purchase - which prevents impulse-buying. In the UK it is almost always better to purchase with a credit card for transactions above £100 but below £30,000. This is due to Section 75 of the Consumer Credit Act 1974 which makes your credit card company jointly liable if something goes wrong. In other words, if you buy something worth £1000 with your credit card, the company fails to deliver for any reason and you cannot get a refund from them directly, you are entitled to make a claim from your credit card company for the full amount. "Nowadays, some banks in some countries offer things like temporary virtual cards for online payments. They are issued either free of charge or at a negligible charge, immediately, via bank's web interface (access to which might either be free or not, this varies). You get a separate account for the newly-issued ""card"" (the ""card"" being just a set of numbers), you transfer some money there (same web-interface), you use it to make payment(s), you leave $0 on that ""card"" and within a day or a month, it expires. Somewhat convenient and your possible loss is limited tightly. Check if your local banks offer this kind of service."
There are quite a few advantages to credit cards in the uk. But don't borrow on them past the grace period. Set up a direct debit to pay amount in full. If you are solvent enough, and organised enough to pay your credit card bill in full each month, then use the credit card.  There are no disadvantages and several plus points, already mentioned. Use the debit card when you would be surcharged for using the credit card, or where you can negotiate a discount for not subjecting the vendor to credit card commission. "Just to add about using debit card as ""credit"" vs ""debit"" way: In addition to the difference of having to enter the PIN when using ""debit"" mode (vs having to sign in ""credit"" mode), for stores that offer cash back (i.e. get cash out of your account at the same time as paying), you can only get cash back when using ""debit"" mode." Credit Cards when I can.  The reason if there is fraud or disputed charges (like I very much disagree with the cell phone charge) a debit card is already gone and I have to get the money back, versus a credit card where I haven't paid anybody anything. Etiquette doesn't really come into the picture here. The business offers a service and I choose to accept it. Personally, I use my debit card as much as possible. For every transaction, I record it in my checkbook. Then, when I do reconciling, I know exactly how much I paid for various categories of stuff. Good for budgeting. Most often my purchases are over $10 but when they aren't, I have no qualms about using the card. When you swipe your credit card, the terminal at the store makes a request of your bank, and your bank has only a few seconds to accept or reject the transaction. Once the transaction is accepted by your bank, it appears in the Pending transactions. At the end of the business day, the store submits all of the final transactions for the day to their bank in a batch, and the banks all trade transactions in a batch, and money is sent between banks. This is the process that takes a couple of days, and after this happens, you see the transaction move from your Pending transactions into the regular transactions area.  Most of the time, the pending transaction and the final transaction are the same. However, there are cases where it is different. A couple of examples: With a credit account, the fact that the final amount is not known for a few days is no big deal: after all, you don't have any money in the account, and if you end up spending more than you have, the bank will happily let you take your time coming up with the money (at a steep cost, of course). With a debit card tied to your checking account, the transaction is handled the same way, as far is the store is concerned. However, your bank is not going to run the risk of you overdrawing your checking account. They also are not going to run the risk of you withdrawing money from your account that is needed to cover pending transactions. So they usually treat these pending transactions as final transactions, deducting the pending transaction from your account balance immediately. When the final transaction comes through, they adjust the transaction, and your balance goes up or down accordingly. This is one of the big drawbacks to using a debit card, in my opinion. If a bad pending transaction comes through, you are out this money until it gets straightened out. My reason for not using direct debit is #4 on Dheer's list. I just don't know where exactly I'm going to have what balance on what day, because I usually don't leave more than $100-$200 on my checking, all my cash is in Savings. I also don't want to direct debit from Savings in order to not break the 6-withdrawals limit accidentally. I use direct debit to my credit card where its available, but most places charge for that and I don't want to pay the extra fee. So, I prefer to pay my bills manually. What I don't understand is the people who pay the credit card bills when the statement arrives. I haven't received a credit card statement in years. Don't they have on-line access? Can't they set reminders there? If so - throw the card away, and get a normal one. Same with mailing checks, by the way. I'm still not even half done with the free checks I got from Washington Mutual 5 years ago. I almost never write checks. All the bills are paid online, whether through bill-pay service or an ACH transfer. You can use the debit card for practically any purchase that you make. You'll have to take the usual precautions and then a few additional ones.   Cards make your life really easy and convenient with some basic precautions.  All the best for your travel and stay in the USA. My two cents. A search quickly led to http://www.cardfellow.com/blog/debit-card-credit-card-difference-charges/ which shows the difference in merchant fees charged. A $200 charge costs $3.50-$3.60, a debit charge, $2.34-$2.39 but a PIN Debit, $1.87. The debit cards are a full percent less cost to the merchant, so the money collected is less to use for rewards. (I can't help but wonder how my card gives me 2% cash back, no fee, when I never pay interest.) I'm not certain if you can get a debit card with it, but if you have a PNC in your area, they have a special kind of account designed around teaching financial literacy to children: https://www1.pnc.com/sisforsavings/tour.html . I'm not sure if you can get a debit card for the child or not, but the custodian gets one I believe, and the child gets a special online login to manage the money, so if you don't mind the name issue, it might be worth looking into. If you don't have PNC, maybe one of the banks in your area have a similar program? "I think it's worth pointing out explicitly that the biggest difference between a credit card (US/Canada) and a debit card (like your French carte de crédit) is that with a credit card, it's entirely possible to not pay the bill or to pay only the ""minimum payment"" when asked. This results in you owing significantly more money due to interest, which can snowball into higher and higher levels of debt, and end up getting rapidly out of control. This is the reason why you should ALWAYS pay off the ENTIRE balance every month, as attested to in the other answers; it's not uncommon to find people in the US with thousands of dollars of debt they can't pay off from misuse of credit cards." "Using cash instead of a debit card lets you see in real time how much cash you have left and where it's going.  It's a lot ""harder"" to see the cash disappear from your wallet than it is to swipe the plastic (whether it's a debit or credit card).  Using cash is a way to keep the funds in check and to keep spending within a budget (i.e. you can't spend it if you don't physically have the cash anymore)." It depends on your bank and your terms of service, but using the card one way or the other may affect things such as how long it takes to process, what buyer protections you have, etc.  It also affects the store as I believe they are charged differently for debit vs credit transactions. 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. Linking the card is primarily to give you (and Paypal) a fall-back option for funding your spending if your bank account doesn't have sufficient funds to process the charge.  If the bank account has sufficient funds, it will work fine in many cases without a credit card. If you have both linked (bank and a credit card), Paypal will transfer funds immediately, as Paypal knows it has an option for getting the funds if the bank has insufficient funds.  However, if you have no credit card linked or remove your only card: If you remove your only card and have a confirmed bank account, you’ll no longer be able to make instant bank payments. Instead they’ll be sent as eChecks, which take 3 to 4 working days to process. This may not matter in many cases, but it may delay things some.  There may also be services who require immediate payment (and won't support PayPal if it's not immediate). There may also be some functional limitations.  The one I see is primarily that some services that are geo-location-specific, Spotify for one example, use the credit card to verify that you are in a particular location (in Spotify's case, for licensing purposes).  They don't seem to accept Paypal unless it's linked to a credit or debit card (even if it's verified via a bank account).  I'm not sure if this is common with other services, but it's something to consider.
