Whenever you write a resume, write a cover letter, or go to an interview, you need to put yourself in the shoes of the person interviewing you.
They have a problem. Maybe that problem is a lack of a specific skill on their team. Maybe it's just a matter of maintaining a certain level of headcount. Or whatever.
They are interviewing people in order to find a solution to their problem. If you pad out your resume or your talk at an interview with stuff that doesn't help them solve their problem, they are likely to select a candidate that not only has the skills to solve the interviewer's problem, but the presentation skills to cleanly and clearly demonstrate those skills without other stuff getting in the way. That candidate has now solved two of the interviewer's problems.
This is all obvious stuff, but it's so obvious that we sometimes forget it - you need to ask yourself how remembering cards will help you solve the interview's problem better than other candidates - and if you can't think of a reason then you probably don't want to put it on your resume.
Depending on how the interview is going, if you're asked to talk about yourself for a bit then it might make a useful conversation piece that will make them remember you. Make sure you relate it to how you think it will improve your skills, so you're remembered as someone who's prepared to try unusual things to improve yourself, instead of being remembered as 'that weirdo'.
