> Plenty of ways to get a credit card without credit history (secured credit cards are typically easiest) and as long as you pay it off before the statement due date

How it works? What the reason for a bank to give credit without interest? I just do not believe it. System must have a way to get interest. If system says it charges no interest, it means that interest payments are hidden. Either behind transactions fees, or by fixed costs covering maintanance of credit card, or by some other ways.

You're correct, US credit card companies do still make a profit on those of us who pay off their balance in full every month and therefore pay no interest.[1]

Visa/MC/Discover/Amex all charge the merchants a percentage (~2%) to process a credit card transaction. I have a cashback card with no annual service fee which pays 1.5% cashback.

Let's say I spend $10,000.00 on this card in 1 year. Visa will collect $200.00 in merchant fees, pay me $150.00 in cashback, and gross profit of $50.00 on my account for 1 year.

Some cards charge an annual service fee which adds to the gross profit.

In a sense you are right -- there is a hidden fee, and it's related to the value that credit cards create for merchants. There are other ways to make money on payments, besides interest. The card company charges the merchant a fee -- perhaps 3.5% -- to process the transaction.

If a customers pays 8.00 USD for a toothbrush with cash, the merchant receives 8.00 USD in cash. If the customer pays with a credit card, the merchant receives 7.72 USD directly in their bank account. They lose 0.28 USD on 8.00 USD. Why do they take this deal?

* Reduced risk of theft and loss. Cash is easy to steal -- it can be stolen by employees, by dedicated robbers, and by passers by.

* Increased likelihood of making a sale. People don't want to carry too much cash, so sometimes they run out; and instead of making an impulse purchase, they just don't make the purchase. Credit makes it much easier for them to make that purchase.
