Be a Beautiful and Unique Like a Snowflake
Business cards are no longer the somber black-and-white affairs they once were. They should showcase your personality and creativity in a way that's appropriate to your career.
If you're working for a legacy financial firm, you may want to go the subdued route, but if you're in the start-up sector, color and playfulness are both assets. That goes double if you're immersed in any sort of creative field, where you will likely be expected to have an eye for aesthetic details. Is your logo up-to-date? Does it need a brand re-fresh? If you have recently updated your website, make sure that it is correctly noted on your business card.
Use the back of the card as well.
Many people overlook the space available on the back of the business card. While it is a great space for others you meet while networking to make a note of where they met you, you can still print some information on the reverse.
Think about media, paper thickness, card shape, color and font when choosing your card and make sure the design is consistent with the personality you showcase on your website and social media accounts.
Yes, it's acceptable link to your social media profiles on your business card, but you shouldn't link to all of them. Does a potential client really need to see your "Dream Wedding" Pinterest board?
Stick to the profiles that best showcase your work and your personality without getting too personal. Your Twitter feed or LinkedIn page are acceptable, but the Facebook profile where you share photos of your fifth cocktail on a Wednesday night is definitely not — and you should probably go ahead and make your Facebook private while you're at it. If you have a personal website or a blog on which you showcase creative projects, be sure to include a link.
Assume that most companies have at least a cursory understanding of what the Internet is and how a URL begins; on a business card, you only have to include the part of the link that comes after the "www."
Lastly, if there's anything the modern design aesthetic can teach us, it's that white space is your friend. Don't make the card too cluttered; QR codes are nifty, but they also take up a lot of room. Only include a QR code on your business card if you're linking to a site that is optimized for mobile viewing.
