A business card is the first tangible impression of your business and remains a standard in business networking. The exchange of business cards is still powerful and more professional than exchanging information via smartphones. Sending an email is not too informal, but business cards are far more professional to bring along to a face-to-face meeting.
Emails can get lost in spam, forgotten, or unintentionally deleted. Business cards are concrete and tactile – they leave in the hands, purse, pocket, or wallet of a new contact. Business cards remain the quickest and most efficient way to exchange information and are acceptable in almost every business setting, eliminating the possibility of an unprofessional appearance.
