Welcome to Online Payments!
How does money actually move when you buy online? We'll map the online payment ecosystem — its key players and where Stripe fits in.
Core Players in Online Payments
Meet the core players: the customer, the merchant, the issuing bank (customer's), the acquiring bank (merchant's), and card networks like Visa and Mastercard.
What's a Payment Gateway?
A payment gateway is the digital point-of-sale: the secure link between your site and the banks. It encrypts card data, sends it for authorization, and relays the reply.
The Payment Processor
The payment processor takes the encrypted data and talks to card networks and banks — checking funds, requesting authorization, and moving the money after approval.
Understanding Merchant Accounts
A merchant account is a special bank account that lets a business accept cards. Approved funds land here first, then settle to your regular account in a few days.
The Online Payment Flow (Simplified)
The payment flow in short: customer enters card, gateway encrypts and sends, processor requests auth, bank approves, response returns, then funds settle.
Stripe Enters the Ecosystem
Juggling all those players is complex — that's where Stripe comes in, acting as an all-in-one solution instead of separate gateway, processor, and account.
Stripe's Integrated Role
Stripe is gateway and processor at once, and covers merchant-account duties by talking to card networks and banks for you — fewer parties, faster setup.
Why Choose Stripe?
Why businesses pick Stripe: simple APIs, global multi-currency reach, great docs, built-in PCI compliance, and extras like subscriptions and invoicing.
