Payment Gateway
What is a Payment Gateway?
A payment gateway is a technology that securely transfers payment information between a customer, a business, and the systems involved in processing a transaction. In a mobile app, a payment gateway can be used to accept payments for products, services, bookings, or other purchases and send transaction data to the appropriate payment provider for processing.
Why it matters
A payment gateway allows businesses to accept digital payments securely within their online services and mobile applications. When creating an app with payment functionality, the business usually needs to connect an appropriate payment service rather than process sensitive payment information independently. The available payment methods, currencies, fees, and technical requirements depend on the selected provider.
Example
A company creates a booking app that allows customers to pay for services from their smartphones. The application is connected to a payment gateway that securely sends the transaction information for processing and returns the payment result to the app.
