Online transactions refer to the process of buying or selling goods and services over the internet. This involves using digital payment methods, such as credit cards, debit cards, or online payment systems like PayPal and Stripe. Customers can browse products on websites or apps, add items to their cart, and complete their purchases from the comfort of their homes. These transactions are facilitated by secure payment gateways that encrypt sensitive information to protect users. Online transactions have become increasingly popular due to their convenience, allowing people to shop anytime and anywhere. However, it is essential to ensure that websites are secure to prevent fraud and identity theft.
