Business cards may be a tried-and-true marketing device, but that's not to say they haven't changed with the times. For a look at recent trends, browse The Business Card group on Flickr or go to Cardonizer, where users have posted stylish, creative examples.

The key is to keep your cards looking up-to-date but not overcrowded. Cards these days cram ever more information into a small space -- in addition to the company name, address, phone number and email address, some people are adding their company's website, Facebook fan page link and Twitter stream. The result? A visually confusing mess.

If you are active in social media, a better bet is to simply list your website. Then, on your site, add prominent links to social-media sites visitors can quickly access if they're interested.

The days when your color choices were limited to white or cream are also long gone. Nowadays, cards come in full color, many with photographs -- and again, that leads many businesses to overcrowd their cards with logos and pictures. Apple co-founder Steve Wozniak even hands out custom-designed stainless steel cards, which fall into the memorable-but-not-exactly-practical category.

While it is easier than ever to design and print your own cards online, hiring a pro is the way to go if you want to project a professional image. With many talented designers laid off from jobs at agencies and magazines in recent years, you'll have your choice of freelancers willing to take on this kind of project.

When designing a business card, think of it as a miniature introduction to you and your business. Do you want to present yourself as innovative and forward-thinking? Then your card should be designed with a modern font and color palette.

By contrast, a simple, two-color business card sends its own message: that you are traditional and no-frills. Even so, the card should include your e-mail address and website -- modern-day business necessities. A good designer can integrate that information with your company's logo and other details to make sure the card isn't overwhelmed with type.

Although creative types may be tempted to make their cards stand out by using nontraditional materials or shapes, make sure the finished product still fits easily into a standard wallet pocket; otherwise they're more likely to get tossed. Also, avoid glossy paper, which makes it difficult for someone to scribble a note on the back.

And remember that business cards aren't meant to be hoarded and admired in private. Get in the habit of handing them out, which is easy if you have one you want to show off.
