You probably don’t think about how your credit or debit card transactions are completed. You just swipe, tap, or wave your card at point-of-sale terminals, or submit the account information to an e-commerce website to make a purchase. After that, the retailer supplies you with the item or service — and you either get the bill or the money is deducted from your checking account.

How and Why it All Works
As money shifts from your credit card or bank account to the company you’re buying something from, the payment processing company charges a fee — called an interchange fee — to the merchant. Although the fee is only a percentage point or so per transaction, the sheer volume and monetary value of these transactions translate into massive profits for the company that facilitates the payments.
But the system helps all parties. After all, customers can purchase what they want in an instant, and merchants are confident the money will swiftly be in their accounts. It usually takes between 24 to 48 hours from the transaction for the funds to arrive in their bank.
As for you, the customer, the money will either be deducted from your checking account or the transaction will appear as a line item on your credit card bill for you to pay.
