1) Business Cards: Make sure they are memorable yet tasteful and clearly convey your brand. Consider a short tag line in lieu of extraneous information such as a physical address. 2) Printed Resumes: You should not be handing out resumes left and right. However, having some on the ready in case it comes up in a conversation is a good idea. 3) Pen and Pad: It never hurts to be able to pull out a small pad to jot down a note. Sure, you have your mobile device, but sometimes that pad really comes in handy. 4) Goals: Although it is not a physical thing to bring to a networking event, taking some time to decide in advance what your goals and metrics for a successful event will be is a way to focus on measurable results.
