Payment Gateways Processors

Payment gateways and processors are the infrastructure that moves money when you buy something online or in person. A gateway captures your payment information and sends it securely to a processor, which communicates with your bank to authorize the transaction. Understanding how these systems work helps you recognize legitimate payment flows, spot potential fraud, and know what to do when a transaction stalls or fails.

These articles explain how different processors handle various payment types—credit cards, debit cards, digital wallets, bank transfers—and what happens behind the scenes during each step. You'll learn why some transactions take longer than others, how chargebacks work when disputes arise, and what protections exist if your payment information is compromised.
