A digital business card is a modern alternative to traditional paper business cards. It typically includes contact information such as name, job title, company name, phone number, email address, and website. Digital business cards can be easily shared electronically through email, text messages, or social media, and often contain interactive elements like clickable links and buttons for easy access to additional information or contact methods. They are environmentally friendly, cost-effective, and offer a convenient way to share and manage professional contact details.
