Turn your brand values into a business card design. Do this by thinking about the customer you’re trying to impress, and deciding what would tell the story of your business for that customer. Your images (if you use any), colors and textures should all be consistent with your existing marketing materials, and all of those should be right in line with the brand values that distinguish your business from everyone else.
If you met two individuals and one was scrambling to find a pen and something to write on and the other person simply pulled out a business card, who would you want to do business with? Showing that you are prepared at all times is a great indicator that you are professional.
A business card is a physical object that a potential prospect leaves the encounter with. Your brand stays with them. If you meet a prospect and exchange email addresses and phone numbers you each walk away with another contact on your mobile phone -- it ends there. If you hand over a creative business card that makes a great impression that person is likely to show it to other people -- putting you and your brand in front of additional prospects.
If your company is all business, your cards should be too; stick to classic designs with minimalist looks and elegant fonts and colors. If your brand is more creative, artistic or playful, you’ve got liberty to use bold images, arresting colors, unusual shapes or humor to get your message across.
