Understanding Payment Systems

Before diving into the technicalities, let’s first understand what payment systems are and how they function.

They facilitate the transfer of funds from customers to merchants, ensuring a seamless exchange of money. There are various types of payment systems available, each with its own advantages and features.

Different Types of Payment Systems

They securely transmit payment data, such as credit card information, to complete transactions. Popular online payment gateways include PayPal, Stripe, Authorize.Net, and Square.

  2. E-commerce Platforms with Built-in Payment Systems: Many e-commerce platforms, such as Shopify, WooCommerce, and BigCommerce, offer integrated payment systems. These platforms provide a convenient solution by combining website building tools with payment processing capabilities.
