A digital card is a virtual version of a traditional card, such as a business card or greeting card, that can be shared electronically. These cards often contain information like names, contact details, and images, and can be sent via email, messaging apps, or social media. Digital cards are convenient and environmentally friendly, as they eliminate the need for paper. Many digital cards use formats like PDF or JPEG for easy sharing and viewing. Some platforms also allow users to create interactive cards that can include links to websites or social media profiles. This modern approach enhances connectivity and communication.
