Can a business refuse to take credit cards?
Businesses are free to decide what payment methods they accept for their goods and services. Businesses sometimes advertise what credit cards they accept by posting some stickers at their door. When your credit card isn't among them and you don't have enough cash with you, ask about your card before you order. If a business doesn't accept your credit card, your best recourse is to take your business elsewhere. When you already ate there and got into an awkward situation because you assumed that they would accept your card, you might also want to write an online review of the place and warn others to bring cash for their visit (but please be fair in the review. When the food and service are decent, a restaurant doesn't deserve a one star rating just because they don't take credit cards). Note that businesses have good reasons to not accept credit cards. It often means additional cost for them in form of: But there is also a more shady reason. Taking payment in cash means that there is no electronic trail of the transaction. That makes it far easier for an establishment to misreport their income. They might under-report it to evade taxes or over-report it to launder money (both are illegal, of course).
Can they reject a hundred dollar bill as a payment of debt?! No. A creditor cannot refuse payment in cash, whatever denomination you use. HOWEVER, when you're buying stuff - you don't owe anything to the business owner. There's no debt, so the above rule doesn't apply. As long as there's no debt in existence, the matter of payment is decided between two parties based on the mutual agreement. The demand not to use large bills is reasonable in places like 7/11 or taxi-cab that are frequently robbed, or at a small retailer that doesn't want to invest into forgery detection and fraud prevention. So the answer to this question: Is it the case where this practice of accepting small bills and   rejecting large bills is perfectly legal? Is yes. You can find the full explanation on Treasury.gov, including code references. It depends completely on the nature of the takeover. When a business is bought, the new owner takes on the obligations of the prior owner, the debts don't just go away. When a business files for bankruptcy, its debts may get discharged, and gift card holders can easily be the first ones to get nothing back. A case in point was Sharper Image who stopped honoring gift cards even while the doors were open as they filed for bankruptcy. 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. Not necessarily. You can issue credit cards without a bank involved, although companies which do so may have additional legal complications, such as usury regulations. As an example, AmEx is a network which also issues cards themselves. The company is not a bank; they sold their banking subsidiary in 2007. It's also possible to get a bank-issued credit card without banking with that same company. Merchants that accept American Express should have decided that the extra costs are worth the increased business (many business travelers only have an Amex Corporate Card).  To complain about people actually using it after they've explicitly decided to accept it is a sign that they made the wrong decision, or that they are very short-sighted.  No one is forcing them to take a particular card. "Why would you consider it null and void? It might be that something went wrong and the business ""lost"" the transaction one way or another. It might be something else. It might never appear. It might appear. In one of the questions a while ago someone posted a link of a story where an account was overdrawn because of a forgotten debit card charge that resurfaced months later. Can't find the link right now, but it can definitely happen." Accepting cash isn't free to the merchant's either.  It needs to be counted, reconciled, stored, and taken to the bank each day.  There is a certain amount that needs to be on-hand, not in the bank earning interest. There is more of a worry about employees taking cash from the register.  There is the chance of inadvertently accepting counterfeit currency.   I'm not sure how the cost of cash compares to the cost of accepting credit card, but there is a cost that cannot be ignored. Because your friend isn't going to like the ~2% charge they have to pay to the credit card company on the $10,000 purchase. Credit card companies make money off of transactions. The cardholder normally doesn't pay any transaction fees (and in fact can make a profit via rewards), but the merchant has to pay a certain amount of money to the credit card company for the transaction. In this case, the apartment owners ate the charge, likely because it was easier for them to send a check than to refund the cost of the fee through the credit card company. If you started doing this a lot to take advantage of this, I would imagine they would get smart and refuse your business (it'll be pretty obvious what you're doing if you're not signing any leases). My understanding it that the signature requirement is at the retailer's discretion. If the merchant decides to require a signature it protects them against fraudulent charge-back claims, but increases their administrative costs. In some situations it just isn't practical for a retailer to require a signature. Consider for example mail-order or online purchases, which I've never had to sign a credit card slip for. "Understood. But based on the OP, it's not categorically clear what they were refusing.   If they refused to quote the balance and/or refused to take a phone payment that was otherwise in keeping with the cardholder agreement (i.e., the cardmember called the correct number for phone payments and balance-checking, etc), then yeah, they were not only being unreasonable, but also violating the contract.   What I read as ambiguous is whether the cardholder was specifically asking for the *payoff* balance/amount, and whether they were following process for phone-payments and balance-checking, etc.   IOW, it's not necessarily ""illegal"" and might not even be unreasonable for the customer-service number to have different departments for balance-checking and phone-payments versus card-cancellation. It's not falsifiably clear from the OP that the cardholder was not asking the person on the other end of the phone for categorical statements of fact that they were obligated to make.   I'm not accusing anyone of lying or saying that the CC company was acting reasonably, I'm just saying that language such as **""They do not provide mid-cycle payoff quotes""** is not evidence that they were doing any kind of funny-business." The Federal Reserve website notes that creditors must accept cash for debts on services already rendered, but that businesses may refuse cash for services not yet rendered unless prohibited by local law. The Treasury website includes examples of businesses limiting what cash they will accept:  For example, a bus line may prohibit payment of fares in pennies or   dollar bills. In addition, movie theaters, convenience stores and gas   stations may refuse to accept large denomination currency (usually   notes above $20) as a matter of policy. A lot of stores, especially smaller ones, won't accept card payments under $10.00. They pay a fee for taking cards and for small transactions it is not worth it. Is this even legal? How can a bank refuse to deposit legal tender in   the United States? Legal for all debts, public or private, doesn't mean quite what I used to think, either.  Per The Fed: This statute means that all United States money as identified above is   a valid and legal offer of payment for debts when tendered to a   creditor. There is, however, no Federal statute mandating that a   private business, a person, or an organization must accept currency or   coins as payment for goods or services. Private businesses are free to   develop their own policies on whether to accept cash unless there is a   state law which says otherwise. Yes, they can refuse loose change. Also, they aren't refusing your deposit, just requiring that it be rolled. What do I do with my change? I do not want to spend the time rolling   it, and I am not going to pay a fee to cash my change. There aren't many other options, change is a nuisance. I believe Coinstar machines reduce/remove their fee if you exchange coins for gift cards, so that might be the best option for convenience and retaining value. I don't carry cash at all unless I know I'm going somewhere which requires it - this includes going to the corner shop for some milk or going to other countries for a week. Cards are easier for me - if a merchant wants my business they will take my money through whatever means they can. I don't think etiquette comes into it. As long as you don't finance and the payment is upfront, its up to you and your customer how to pay. If you provide the product before the payment is being made or finance in any way (i.e.: there's debt), then the Canadian dollar, being legal tender in Canada, must be accepted. Considering the large amount, you would probably not be accepting cash anyway, so the point is moot. How they pay their credit cards is not your problem. However, do take into the account the currency exchange rates and fees that add costs to purchasing your product. If you don't have any physical presence (i.e.: online store only, no physical location on Canadian soil), then it goes by the rules of the jurisdiction where you've incorporated. Check with the local legal professional to be sure.
