## Understanding Payment Gateways
### What is a Payment Gateway?
A payment gateway acts as the intermediary between a business's website or app and the financial institutions involved in a transaction. It is responsible for securely transmitting payment data from the customer to the merchant.
### Why Payment Gateways Matter for QR Code Payments
Payment gateways are indispensable in QR code payments because they ensure secure and swift transactions. When a customer scans a QR code, the payment gateway processes this request by verifying the information and facilitating the transfer of funds.
### Real-World Example: Starbucks
Starbucks has successfully integrated QR code payments into its mobile app, allowing customers to make seamless transactions through a robust payment gateway. This integration enhances customer experience by providing a quick and efficient payment method.
