Payment processor

A payment processor is like a grown-up piggy bank that helps you pay for things. When you want to buy something, like a toy at the store or pizza for dinner, you need to give the person selling it some money. But instead of giving them real money, you can put your money in the piggy bank and the piggy bank will give the money to the person for you.

The person selling the toy or pizza also has a piggy bank where they keep their money. When you give your money to your piggy bank, the piggy bank talks to the other piggy bank and makes sure that the right amount of money is taken out of your piggy bank and put into the other person's piggy bank. That way, the seller can feel safe knowing that they have their money, and you can feel safe knowing that you bought what you wanted.

Companies also use payment processors like a piggy bank to help them get paid for things that they sell online. When you buy something from a company on the internet, you give your piggy bank information to the payment processor so they can take the money out of your piggy bank and give it to the company's piggy bank. The payment processor helps the company make sure that they get their money, and you can feel safe knowing that your money is going to the right place.

So basically, a payment processor is a piggy bank that helps you and the people or companies you buy things from to manage their money and make sure that everyone gets paid the right amount.
