Primer
What is a Payment Processor?

A payment processor is a system that helps move money between customers and businesses.

It acts as a middle layer between the buyer, banks, and the seller.

Payment processors help transactions happen quickly and securely.

How payment processing works:

Step 1:
Customer enters payment information.

Step 2:
Payment processor receives the request.

Step 3:
Banks verify funds and security.

Step 4:
Approval or decline is returned.

Step 5:
Money moves to the merchant account.

What payment processors can handle:

credit cards
debit cards
online payments
mobile payments
subscriptions
recurring billing
digital wallets

How payment processors protect information:

Encryption
Protects information while traveling.

Tokenization
Replaces sensitive card data with safe identifiers.

Security standards
Help reduce fraud and risk.

Think of a payment processor like this:

Customer → Cashier → Bank → Store

The payment processor acts like the cashier and messenger.

It asks:
"Can this payment happen?"

Then returns the answer.

Why payment processors matter:

Without payment processors, online stores would need to handle payment systems themselves.

Payment processors help businesses accept money safely and efficiently.
