Programmer Business Cards?

This is a new thing for me. I have been a programmer now (officially) for 1 yr. To be honest, I don't think I have had more than a couple of opportunities when I could have used a "business card." Do programmers need business cards? GT said he has only used a handful in the couple decades he has worked as a programmer. However the new Kid on the block says she has used them quite frequently.

So do I need a business card? I don't know. What do you think? I guess if I had some then the opportunities might present themselves. It would be kind of like that process when you buy a new car and then you see them EVERYWHERE. Work would pay for them. So should I get some. I don't know, probably. Get the cards and let them collect dust.
