This seems like a shameless endorsement but I think many might find it useful. Are business cards dead? Far from it. Most of my freelance jobs come from a business card. Anytime someone asks you if you have a card, you should say, “Yeah. Ba BAM!” and give it to them. Iphones and Android have the bump app but that is a bit clumsy.
I still think everyone in business needs a card. If you are looking for a good deal. Here’s one. A student showed me this site. She order samples and had a good experience with the company.
