A “calling card” is used for social purposes, and properly only states the name of the person.
A “business card” is used for professional purposes, and contains relevant professional information, including job title, firm, and business contact information. (A business card is often used socially, as a convenient means of trading information, but not in the same way as a calling card.)
While being a college student isn’t what we usually consider a “profession,” Agnostic Pagan’s needs definitely fall into the “business card” category, especially as he wants to use them for networking. Since he doesn’t have a job title, just the name of the “firm”–aka his university and maybe his department–is sufficient.
To answer the OP’s specific questions:
**So what do people do in this situation? Has anyone ever used personal cards? **
I was in the same position when I was in graduate school. At my mom’s suggestion, I used those Avery make-your-own business cards. I formatted them like a traditional business card with my name, the name of my university and program, and personal contact information. They came out looking great. And my mom is always right–see below.
What are your experiences?
My experiences were entirely positive. I was really glad to have them. It avoided the awkwardness of not having a card to trade, as the OP suggests. It also gave me instant credibility. People took me more seriously for having a card, even though it was just a simple little thing. I scored a lot of free books and materials by handing my card to vendors. Also, people were less likely to lose it or throw it away by accident. After the first conference that I had them, all my buddies got some too.
Now, it might seem a little unusual for an undergraduate to have a card, but the OP states he is “back in school,” and actively looking to make contacts, so I’m surmising that he is a slightly older student who is serious about his studies. It won’t make him look like a “poser” if he doesn’t make it fancier and more elaborate than it needs to be.
So, I say–do it. You won’t regret it. And if for some reason you don’t feel comfortable pulling it out, well, you can just leave it in your pocket.
