What do you think of when you imagine a business card? In general, you most likely think of a small stock-paper rectangle that has essential contact information printed on it and, probably, a logo. While this standard method has traditionally been an effective way to exchange business information, it's not entirely memorable. Thinking outside the box when formatting business cards is a great way to increase your networking efforts. If you'd like to make your business cards more creative, here are a few tips to get you up and running.Add Texture This is probably the easiest way to make your business cards more memorable without getting too crazy. A card with texture engages the sense of touch, which adds another layer of memory to the experience. Sure, it sounds silly, but if the brain can remember what the card felt like, it will likely also remember what the card represents. Check out this great example of a textured business card. Make Them Share-worthy If your card is worth sharing, it will become a practical social experience. Essentially, this means adding some creative element to the card that the receiver will want to share with his or her friends. Think about this hilarious mustache card, designed to be held in front of the face as an on-the-go disguise. It is exactly the kind of creative design that is sharable. Making a card share-worthy will have a multiplying effect on your networking efforts. Here is a great example. Make Them Digital Going green is a great technique when making your business cards. Instead of printing out hundreds of little cards that will eventually end up in the garbage, consider making your business cards digital. The best way to do this is by utilizing QR codes, a rising trend among smartphone users. Not only will a digital card reduce printing costs, using a QR code will create a level of interactivity between you and your audience (an important facet of generating brand loyalty). Here are some tips on using QR codes.
