What are the reasons to get more than one credit card?
In the case of reward cards, different cards may offer different rewards for different kind of purchases. For example, in the UK, one of the Amex cards offers 1.25% cashback on all purchases, whereas one of the Santander cards offers 3% on fuel, 2% or 1% on certain other transactions, and nothing on others. Of course, you then have to remember to use the right card! Another reason is that a person may use a card for a while, build up a good credit limit, and then move to a different card (perhaps because it has better rewards, or a lower interest rate, etc) without cancelling the first. If it costs nothing to keep the first card, then it can be useful to have it as a spare. Another reason is that the amount of unused credit you have is a positive factor on your credit score.  It's generally easier to open several different accounts for $X dollars each with different banks than to get your current bank to raise your limit severalfold in a single go.  Your current bank has to worry about why you suddenly are asking for a large additional amount of credit; while other banks will be willing to offer you smaller amounts of credit in the hope that you transfer your business from your current bank to them. A friend of mine has two credit cards.  He has specifically arranged with the card issuers so that the billing cycles are 15 days out of sync.  He uses whichever card has more recently ended its billing cycle, which gives him the longest possible time between purchase and the due date to avoid interest. I have a fair number of cards floating around some reasons I have opened multiple accounts. I am not saying that it is for everyone but there are valid scenarios where multiple credit cards can make sense. Many reasons mentioned already. The reason why I have multiple is missing: I have a personal card for my private use and a company card for company use. Another good reason: if you have to replace a card due to damage, loss, or identity theft it's nice to have a backup you can use until the new card for your primary account arrives. I know folks who use a secondary card for online purchases specifically so they can kill it if necessary without impacting their other uses, online arguably being at more risk. If there's no yearly fee, and if you're already paying the bill in full every month, a second card/account is mostly harmless. If you have trouble restraining yourself with one card, a second could be dangerous. "3 reasons I can think of: I once worked for a bank and when credit scoring for loans, if you had been approved by different institutions, you were given a better score. So if you held a Visa and Mastercard (as opposed to two Visa cards) your credit score would go higher. More than 6 cards though looked suspicious and your score would take a big hit. Having more than card has helped me when getting special offers multiple times from some websites where it was limited to ""one per customer"" though most just used your address or email account. If you owed $1000 in total which you can't pay off in one go, it is better to have that split across two cards. You would be paying interest on $500 on each card but when you have one card paid off, the interest you would be paying on the other would be based on the original debt to that one card of $500 (not $1000). I hope that makes sense." 1- To max out rewards. I have 5 different credit cards, one gives me 5% back on gas, another on groceries, another on Amazon, another at restaurants and another 2% on everything else. If I had only one card, I would be missing out on a lot of rewards. Of course, you have to remember to use the right card for the right purchase. 2- To increase your credit limit. One card can give you a credit limit of $5,000, but if you have 4 of them with the same limits, you have increased your purchasing power to $20,000. This helps improve your credit score. Of course, it's never a good idea to owe $20,000 in credit card debt. I keep one card just for monthly bills (power company,car loan, etc.).  This one is unlikely to get hacked so I won't have to go change the credit card information on my monthly bills.  I pay the credit card from my bank account.  I just don't want a lot of businesses with direct access to my bank account. Someone mentioned sign up bonuses but only mentioned dollar values. You might get points, sweet, sweet airline points :) which some might find compelling enough to churn cards so they always have a few open. I got a Capital One credit card because they don't charge a fee for transactions in foreign currencies. So I only use it when I travel abroad. At home, I use 3 different credit cards, each offering different types of rewards (cash back on gas, movies, restaurants, online shopping etc). There is almost no reason to get a second credit card - this is a very good arrangement for your creditor but not for you. Credit cards have high rates of interest which you have to pay unless you pay the credit off every month. Therefore, increasing your total credit capacity should not be your concern.  Since internet technology lets you pay off your balance in minutes online, there is no reason to have multiple cards in order to avoid running out of a balance. If, on the other hand, you do not pay your existing card off every month, than getting another card can be even more dangerous, since you're increasing the amount of debt you take on. I'd say at most it would make sense for you to grab a basic VISA, since most places do not accept AMEX. I would also considering cancelling the AMEX if you get the VISA, for reasons above.
"Congratulations on recognizing your problem and getting serious about paying down your debt. That's the first step. If you have a loan with 80% interest, yes, get that paid off as quickly as possible. Much better to be paying even the outrageous 20% on a credit card than the astounding 80%. As others have noted, if you can get a consolidation loan or refinance that 80% to something more realistic, do it and do it as soon as possible. Heck, if you have the credit limit, use the credit card to off the 80% loan. 20% on a credit card is better than 80%. Of course you may not have enough credit limit to do that. Cash-back rewards are nice if you are paying off the credit card balance each month. But in your case, you're not. 25% with a 2% cash back reward means you're still paying 23% the first month and 25% every month after that. That's worse than 20%. Remember you pay the interest on your balance every month that you don't pay it off, while a cash-back is a one-time thing. So if you're not going to pay off the balance, AT BEST a cash back reward could be effectively subtracted from the interest rate. 20% with a 2% cashback is effectively somewhere between 18% and 20%. If you're comparing 20% with 2% cashback to 19%, could be complicated to figure out which is better. But it's clearly worse than anything more than 20%. Besides that, you don't say what your total debt is in relation to your income. If you have a lot of debt, I'd say first thing is to figure out what you can do to cut your expenses. Lots of things that people call ""fixed expenses"" aren't really fixed at all, they just take some effort to cut. Like if you have a big expensive house and you're paying a large mortgage, you can (probably) cut that by selling the place and moving to a cheaper house. (I say ""probably"" because the housing market may make it impossible to sell for enough to improve your situation.) If you have large heating bills, you can turn the thermostat down and get used to wearing a sweater around the house. Etc.  Final note: I've talked to a fair number of people with debt problems, and I often hear them say, ""Yes, I really need to cut my spending and start paying off these debts. And I intend to ... right after I buy this one last thing that I really really want."" But of course after that there's one more vital purchase, and then another, etc. Avoid falling into this trap." "Some reasons I take low-interest loans are: Leverage. If the loan's rate is low enough, then I can invest the cash in something fairly low-risk, and make more money than I pay in interest. The interest rate has to be pretty low, say below 4% or so. My auto loan is low enough and my home loan is low enough if you count the tax deduction. Obviously you have to invest in something riskier than cash here, though. And consider taxes, which lower the rate you're paying on a home loan, but also lower the returns you're getting on any bonds you invest in. Liquidity and flexibility. If I have N thousands in cash instead of tied up in my house, then I could use that money to survive many months of unemployment for example, or handle any other emergency. But if you become unemployed or have some other emergency, it will be too late to get a home loan. Credit rating. It's good to use some credit, just so you can get more if you need it. But this isn't a reason to take a particular loan, just a reason to have some kind of credit card or loan. Budgeting. When budgeting, it's best to think of expenses such as cars and houses in terms of a monthly cost, so you can see how they nudge out or allow other spending. (When negotiating with a car dealer, of course, use total cost so you don't get screwed by him messing with interest rates.) I wouldn't take a loan just to ease the budgeting (you can always manually ""amortize"") but it's a nice side effect. For credit cards, there are more buyer protections and you get a nice transaction log (again useful in budgeting). Also you don't have to carry around cash, or worry about your checking account balance. So credit cards are just convenient. But even though my card has a very low rate, it isn't low enough that I want to keep a balance month-to-month, so I don't use credit cards to actually borrow money." Please realize that your issuer can close the account for any number of reasons.  Inactivity is one, as having a credit line open costs them money and if you never charge anything, the company doesn't get any transaction fees from vendors nor does the company get to charge you any interest. An occasional charge is likely to keep your card from being closed automatically, but it is not a guarantee. Another reason they may close the account is that you have other bad marks show up on your credit score, or their criteria for offering you the card change so you no longer match their target demographic. I have a credit card issued by my credit union that I have not used for a couple of years. They will not close the card account because my other accounts are still very profitable for them. If I were not an otherwise profitable customer, I wouldn't be surprised if they closed my credit card account. If you are serious about keeping the account open, you should probably have more than a trivial amount of usage. I don't know of any that are comparable to credit cards. There's a reason for that. Debit cards, being newer, have a much lower interchange rate. Since collecting on debt is risky and less predictable, rewards / miles are paid from those interchange fees. This means with a debit card there's less money to pay you with. So what can you do? Assuming your credit isn't terrible, you can just open a credit card account and pay in full for purchases by the grace period. I don't know how all cards work, but my grace period allows me to pay in full by the billing date (roughly a month from purchase) and incur no finance charges. In effect, I get a small 30 day loan with no interest, and a cash back incentive (I dislike miles). You're also less liable for fraud via CC than debit. If you are planning to get new cards, it is probably best to open the accounts as soon as possible to start establishing a history of good credit use. You might also wish to open multiple accounts so that future lines will have less of an impact on your average age of open credit lines. Since you will probably have higher interest rates it is also advisable never to carry a balance on any of your newly acquired cards. This will prevent a recurrence of the problems you are now trying to recover from. I would try to avoid mixing business expenditure with personal expenditure so a second credit card might be a good idea. That said, I did get a business credit card for my company in the UK as I didn't want to be personally liable for the money that was spent on the business card (even though I owned 100% of the business) in case things went horribly wrong. As I didn't fancy signing a personal guarantee, this meant that the limit was quite low but it was good enough in most cases. 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. You could conceivably open a few accounts.  For example, a bank account and a credit card account.  Then the accounts will be older when evaluated for credit when you return.  This would look better than opening fresh accounts later.  But don't expect a big difference in score.  And you'll be stuck with those accounts in the future, otherwise you lose the benefit.  I wouldn't worry about maintaining balances now.  You can wait until you come back.  Occasional purchases may be helpful.   What they really want to see is a regular and sustained use of accounts without missing payments or overextending.  But if you're not going to be here, you can't really do that.  Note that good credit scores are based on seven years of data, preferably a lot of it.  Opening a few accounts can't substitute for that, even if you put balances on them.   If you're not here, you won't be paying rent or utilities.  You won't have a proven payment history on the most common accounts.   If money were no object, you could do something like purchase a house or condo that you could rent out, utilities included.  That would build up a payment history.  But if money were no object, you probably wouldn't be worried about your credit score.  It's more practical to just live normally and be sure that you always live within your means so that you don't experience negative credit events.   You might think about why you want a good credit score.  Is it to borrow a lot of money?  You might be able to spend money to achieve that.  Is it to save money on future borrowing?  If it costs money now, how much will you save total?   Opening accounts now that you won't really use until you return is about the only thing that you can do that won't cost you money.  Perhaps put a balance on the bank account--at least you'll get that money back some day.  Maintaining a balance on the credit cards would cost you money in interest charges, and you don't really benefit from an improved credit score until you use your credit.  So the interest fees aren't really buying you anything.
