Digital cards are virtual versions of traditional cards, such as business cards, greeting cards, or credit cards. They can be created, shared, and stored on electronic devices like smartphones and computers. Digital cards often include interactive features, such as links to websites or social media profiles, making them more versatile than their physical counterparts. These cards are typically designed using software or apps, allowing users to customize their appearance and content easily. Digital cards can be shared via email, messaging apps, or social media, promoting convenience and reducing paper waste. They are becoming increasingly popular in both personal and professional settings.
