Business card for Ph.D. student - what should be included? I'm a Ph.D. student considering getting business cards printed to facilitate follow-ups after conferences, etc. I am barely in touch with industry but I'm in a field where business cards are common.

My university has a set layout, but we have quite some freedom on what to include. There are some questions on whether we actually need a business card as a graduate student, but here I'm more interested on what to include on them.

I'm thinking at least:


Name
Title
E-mail (as it is the primary form of communication for academics)
Post address of university


And maybe: 


LinkedIn 
Personal page


I'm hesitant to include:


Room number (we occasionally switch; updated room number is found on personal page)
Telephone (same as above; could include cell number)


Not including telephone may be a bit harsh, but I'm curious whether you have some input in these matters. What should be included and what is less important?
My experience of business cards in academia is that they are mostly just an easier way to share contact information than scribbling it on a napkin.

As such, the only things that are really important are institution, name, title (because everybody will expect it), and sets of preferred contact information.

As such, if you want people calling you, put down your phone number; if you don't want people calling you, don't put it down.  Likewise for all of the other standard aspects.  You probably should have a web page that you want people to visit.

As for social media sites like LinkedIn: I'm rather dubious about them, simply because there are potentially so many.  I think one wouldn't be a problem, but the extrapolator in my mind goes to a ridiculous image of somebody handing me a card with their LinkedIn, Twitter, Google+, ResearchGate, Facebook, etc.  Don't be that person, or else if I meet you at a conference and you hand me your card, I may have a difficult time avoiding laughter.
