When a customer enters card details, the gateway encrypts them, passes them along for approval and reports back whether the payment went through. It is the online version of the card terminal at a shop counter. Well-known examples include Stripe, PayPal, Square and Authorize.net, and many combine the gateway and merchant account into one service.<\/p><h2>Why It Matters for Your Business<\/h2><p>Your choice of gateway affects fees, how quickly money reaches your bank, which payment methods you accept and what your checkout looks like. A cleaning company that wants deposits online needs a gateway that works with its booking system. A shop selling to repeat customers might want one that supports saved cards, subscriptions or digital wallets like Apple Pay and Google Pay.<\/p><h2>Good to Know<\/h2><p>Tip: choose a gateway that handles card details on its own secure systems, through hosted fields or a hosted payment page. That way card numbers never touch your server, which greatly reduces your security and compliance burden. Before launch, run test payments, refunds and a failed card to make sure each case behaves properly.<\/p><div class=\"sfl-box\"><h4>Related terms<\/h4><div class=\"sfl-rel\"><a href=\"\/fr\/learn\/glossary\/merchant-account\/\">Merchant account<\/a><a href=\"\/fr\/learn\/glossary\/checkout\/\">Checkout<\/a><a href=\"\/fr\/learn\/glossary\/pci-dss\/\">PCI DSS<\/a><a href=\"\/fr\/learn\/glossary\/shopping-cart\/\">Shopping cart<\/a><a href=\"\/fr\/learn\/glossary\/woocommerce\/\">WooCommerce<\/a><\/div><\/div><nav class=\"sfl-pn\"><a href=\"\/fr\/learn\/glossary\/page-speed\/\"><small>\u2190 Previous<\/small><b>Page speed<\/b><\/a><a href=\"\/fr\/learn\/glossary\/pci-dss\/\" class=\"r\"><small>Next \u2192<\/small><b>PCI DSS<\/b><\/a><\/nav><\/article><aside class=\"sfl-aside\"><div class=\"sfl-box sfl-box-o\"><h4>Need this done right?<\/h4><p>Fixed-price websites from $800, built and launched for you in as little as 5 days.<\/p><a class=\"sfl-btn sfl-btn-w\" href=\"\/fr\/web-design-development\/#pricing\">See website packages<\/a><\/div><div class=\"sfl-box\"><h4>More in Back End &amp; Integrations<\/h4><div class=\"sfl-chips\"><a href=\"\/fr\/learn\/glossary\/server-side-language\/\">Server-side language<\/a><a href=\"\/fr\/learn\/glossary\/php\/\">PHP<\/a><a href=\"\/fr\/learn\/glossary\/database\/\">Database<\/a><a href=\"\/fr\/learn\/glossary\/mysql\/\">MySQL<\/a><a href=\"\/fr\/learn\/glossary\/database-table\/\">Database table<\/a><a href=\"\/fr\/learn\/glossary\/api\/\">API<\/a><a href=\"\/fr\/learn\/glossary\/integration\/\">Integration<\/a><a href=\"\/fr\/learn\/glossary\/webhook\/\">Webhook<\/a><\/div><\/div><\/aside><\/div><script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"DefinedTerm\",\"name\":\"Payment gateway\",\"description\":\"A payment gateway is the service that securely sends a customer's card or wallet details from your website to the banks for approval and returns the result.\",\"url\":\"https:\/\/sitefitters.com\/learn\/glossary\/payment-gateway\/\",\"inDefinedTermSet\":{\"@type\":\"DefinedTermSet\",\"name\":\"Business Website 101 Glossary\",\"url\":\"https:\/\/sitefitters.com\/learn\/glossary\/\"}}<\/script>","protected":false},"excerpt":{"rendered":"<p>Learn \/ Glossary \/ Back End &amp; Integrations Payment Gateway Explained.
