A payment gateway is a technology that enables online merchants to accept and process payments made by customers on their websites or mobile apps. Payment gateways offer a variety of services to facilitate secure and efficient payment transactions. Here are some of the typical services offered by payment gateways:

Payment Processing: The primary function of a payment gateway is to securely process various payment methods, including credit and debit cards, digital wallets, bank transfers, and more.

Payment Authorization: Payment gateways verify the validity of the payment method and ensure that the customer has sufficient funds or credit to complete the transaction.

Security Features: Payment gateways employ encryption and security protocols to protect sensitive payment data, reducing the risk of fraud and unauthorized access.

Payment Routing: Gateways route transactions between the merchant's website and the acquiring bank or processor, ensuring that funds are properly transferred.

Multi-Currency Support: Many payment gateways support transactions in different currencies, allowing merchants to serve a global customer base.
