A professional business card needs to fit the branding of your business, display your logo prominently, and highlight your website and contact details, so the people you connect with can find you online, on social, or via email.
When you meet someone that could potentially be a great prospect or connection, do not you want him or her to walk away with a great first impression? A memorable business card does a lot more than just pass on an email address or phone number.
Most business cards are paper, although there are lots of other options, from plastic and wood to metal and slate. Assuming you go with paper, you need to choose thickness, coating, color and weight. All of these can affect the price.
Everything we do in business today is digital -- sending mail, signing contracts, attending meetings, even networking. The business card is one thing that digital will not fully replace anytime soon.
