Explanations on credit cards in Canada
"A credit card is a way to borrow money. That's all. Sometimes the loans are very small - $5 - and sometimes they are larger. You can have a credit card with a company (bank or whatever) that you have no other relationship with. They're not a property of a bank account, they are their own thing. The card you describe sounds exactly like a debit card here, and you can treat your Canadian debit card like your French credit card - you pay for things directly from your bank account, assuming the money is in there. In Canada, many small stores take debit but not credit, so do be sure to get a debit card and not only a credit card. Now as to your specific concerns. You aren't going to ""forget to make a wire."" You're going to get a bill - perhaps a paper one, perhaps an email - and it will say ""here is everything you charged on your credit card this month"" along with a date, which will be perhaps 21 days from the statement date, not the date you used the card. Pay the entire balance (not just the minimum payment) by that date and you'll pay no interest. The bill date will be a specific date each month (eg the 23rd) so you can set yourself a reminder to check and pay your bill once a month. Building a credit history has value if you want to borrow a larger amount of money to buy a car or a house, or to start a business. Unlike the US, it doesn't really have an impact on things like getting a job. If you use your card for groceries, you use it enough, no worries. In 5 years it is nice to look back and see ""never paid late; mostly paid the entire amount each month; never went over limit; never went into collections"" and so on. In my experience you can tell they like you because they keep raising your limit without you asking them to. If you want to buy a $2500 item and your credit limit is $1500 you could prepay $1000 onto the credit card and then use it. Or you could tell the vendor you'd rather use your debit card. Or you could pay $1500 on the credit card and then rest with your debit card. Lots of options. In my experience once you get up to that kind of money they'd rather not use a credit card because of the merchant fees they pay." Is my understanding okay ? If so, it seems to me that this system is   rather error prone. By that I mean I could easily forget to make a   wire some day and be charged interests while I actually have more than   enough money on the check account to pay the debt. Which is where the credit card company can add fees so you pay more and they make more money. Don't forget that in the credit case, you are borrowing money rather than using your own. Another thing that bothers me is that the credit card apparently has a   rather low credit limit. If I wanted to buy something that costs $2500   but only have a credit limit of $1500, can I make a preemptive wire   from my check account to the VISA account to avoid facing the limit ?   If so, what is the point for the customer of having two accounts (and   two cards for that matter...) ? If you were the credit card company, do you believe people should be given large limits first? There are prepaid credit cards where you could put a dollar amount on and it would reject if the balance gets low enough. Iridium Prepaid MasterCard would be an example here that I received one last year as I was involved in the floods in my area and needed access to government assistance which was given this way. Part of the point of building up a credit history is that this is part of how one can get the credit limits increased on cards so that one can have a higher limit after demonstrating that they will pay it back and otherwise the system could be abused. There may be a risk that if you prepay onto a credit card and then want to take back the money that there may be fees involved in the transaction. Generally, with credit cards the company makes money on the fees involved for transactions which may come from merchants or yourself as a cash advance on a credit card will be charged interest right away while if you buy merchandise in a store there may not be the interest charged right away. If so, it seems to me that this system is rather error prone. By that I mean I could easily forget to make a wire some day and be charged interests while I actually have more than enough money on the check account to pay the debt. I have my back account (i.e. chequing account) and VISA account at/from the same bank (which, in my case, is the Royal Bank of Canada). I asked my bank to set up an automatic transfer, so that they automatically pay off my whole VISA balance every month, on time, by taking the money from my bank account. In that way I am never late paying the VISA so I never pay interest charges. IOW I use the VISA like a debit card; the difference is that it's accepted at some places where a debit card isn't (e.g. online, and for car rentals), and that the money is deducted from my bank account at the end of the month instead of immediately. "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."
Apparently it is up to the credit card company on how they want to report your available balance. Another disadvantage to the no-limit   credit card may not be apparent to   most people, but it is something noted   by organizations like The Motley Fool,   which is expert in many issues of   finance and investment. Part of your   credit  score, about 30%, considers   the amount of money you have borrowed,   and the limit on your present credit   cards. A no-limit credit card company   may report your limit as $0 if you   have not used the card, or they may   report  a maximum limit available to   you. They may not, nor are they   obligated, to report times when you   put tons of expenses on a credit  card   and then paid them off. While some companies will report your   timely payments and paid off amounts,   others simply report an extremely low   limit. For instance if you spent $100   US Dollars (USD), your limit might be   considered $100 USD, or it may merely   be reported as zero. You’ll need to   check with a credit card company on   how they report payments and limits on   a no-limit credit card before you   obtain one. Some people who are   scrupulous are paying off their cards   at the end of each month suffer major   losses to their credit score, without   even realizing it, if their spending   ability is rated at zero, or their   payments don’t count toward showing   credit worthiness. Source In the UK there is a significant difference between taking money out of a bank account and out of a credit card account. Banks typically require explicit authorisation before they will transfer money out of a bank account - for example a direct debit agreement. (North American banks are much less strict, and will transfer your money to any reasonably reputable financial organization who asks for it - don't get me started!). However credit cards run very differently. Essentially the onus is on the vendor to get the authorization, which is why you can sign a credit card slip at the corner store, or give your credit card details over the phone, or fill in an online form, and have your credit card account charged. When you signed the credit card agreement you agreed to let people do this. It's also why the credit card company will reverse a transaction if you claim it was unauthorized. So essentially PayPal is like the specialty store you phone up to order something and give your credit card details to - they have just as much authorization to charge your account. Your only protection is that the credit card company will investigate any transactions you claim are fraudulent, and will reimburse you if it is- even if they can't recover the money themselves. Find a good commercial bank in the us, or almost any bank in Canada, and exchange cash. Or use an ATM card in Canada; the surcharge is often minimal. (Check with your bank before traveling). You may or may not get a good exchange rate from your hotel desk; some view it as a courtesy, others as a service. You may be able to simply pay with American cash, near the border, but check the exchange rate. Or, for small amounts, you can simply not worry about whether you're getting the best possible exchange rate or not. I visit Canada periodically, and I use a mix of these solutions. Including that last one. The easiest way is almost definitely through a Canadian bank.  They can get your American credit history through Equifax.  American Express in Canada will have no problem giving you one if you have an American Express in the US, as well.  It would be easier if you went through TD Canada Trust since there's TD Bank NA in the States, or BMO since they own Harris Bank in the States.  Oh, and doesn't Bank of America have Canadian branches? I'm in the process of doing the reverse (getting US card when I'm from Canada).  I use XE Trade to transfer money -- the rates are great and it takes only 2 days for a transfer to go through if you use wire transfers ($25 charge) or online bill payment through the bank (free). 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. "In the end, all these fees hurt the average consumer, since the merchant ultimately passes cost to consumer. Savvy consumers can stay at par or get ahead, if they put in the effort. It's a pain, but I rotate between 4 cards depending on time of year and type of purchase, to optimize cash back. My cards are:  1. 5% rewards card on certain categories, rotates each quarter 2. 2% travel/dining card (fee card, but I travel a bunch so it's worth it, no foreign transaction fees) 3. 1.5% rewards card for everything else 4. Debit card (swiped as a CC) for small purchases (i.e. lunches) at credit union for ""enhanced"" high interest checking account, requiring certain # swipes/month. This alone returns to me ~$800/yr." Every reward program has to have a funding source. If the card gives you x percent back on all purchases. That means that their business is structured to entice you to pump more transactions through the system. Either their other costs are lower, or the increased business allows them to make more money off of late fees, and interest. If the card has you earn extra points for buying a type of item or from a type of store (home stores improvement in the Spring), they are trying to make sure you use their card for what can be a significant amount of business during a small window of time. Sometimes they cap it by saying 5% cash back at home improvement stores during the spring but only on the first $1500 of purchases. That limits it to $75 maximum. Adding more business for them, makes more money for them. Groceries and gas are a good year round purchase categories. Yes there is some variation depending on the season, and the weather, but overall there is not an annual cliff once the season ends. Gas and groceries account for thousands of dollars a year these are not insignificant categories, for many families are recession proof. If they perceive a value from this type of offer they will change their buying behavior.  My local grocery store has a deal with a specific gas station. This means that they made a monetary deal. Because you earn points at the grocery store and spend points at the gas station, the grocery store is paying some compensation to the gas station every time you use points. The gas station must be seeing an increase in business so theoretically they don't get 100% compensation from the grocery store.  In cases where credit cards give airline miles, the credit card company buys the miles from the airline at a discount because they know that a significant number of miles will never be used.
