Online Shopping Cart Transaction

An E-commerce payment system or online shopping cart (card-not-present) is the technology that allows an online store to accept and process digital payments from customers. It is a core component of merchant services and enables secure transactions using credit cards, debit cards, digital wallets, bank transfers, and other online payment methods. Without an ecommerce payment system, an online store would not be able to complete purchases or move funds from the customer to the business.
