Use traditional 3.5" X 2" business cards to promote new services, products, specials or whatever is new at your business. They would still have your contact information. Use them to drive business to your website or location. Treat them as promo cards with a personal circulation. A clever new way to celebrate your brand.
When you go to a networking event in your community, you can take the opportunity to NOT hand out your traditional card but instead, hand out your "what's new card." One great result is that it initiates conversation on your "news." It's a simple idea, but one that is inexpensive and novel. It doesn't matter what size company you have - there's always great news to spread. What could you put on your promo card?
