Virtual cards are digital versions of traditional credit or debit cards. They are typically issued by banks or financial services and can be used for online purchases. Unlike physical cards, virtual cards do not have a physical form and are generated through an app or website. They often come with unique card numbers, expiration dates, and security codes, providing an extra layer of protection for online transactions. These cards can help users manage their spending and enhance security. For instance, they can be set for one-time use or limited to specific merchants, reducing the risk of fraud. Many people use virtual cards for subscriptions or online shopping, making them a convenient option in today's digital economy.
