In an era where online shopping dominates global commerce, payment gateways make it possible for businesses to accept payments from credit cards, debit cards, e-wallets, and even cryptocurrencies in some regions. They play a vital role in maintaining trust between consumers and merchants through encryption and fraud detection systems.
The concept originated in the late 1990s with the rise of online marketplaces. Over time, technologies such as PCI-DSS compliance, tokenization, and API integration have transformed gateways into highly sophisticated systems. Today, global ecommerce platforms rely on gateways like Stripe, PayPal, Razorpay, and Adyen to manage transactions efficiently and securely.
