If you feel confident in your ability to read people, you may feel more inclined to give one card to him or her rather than the other.
It comes off to me as a sneaky attempt to get a job, at which point I would try to end the conversation as politely but hastily as possible and discard your card when you are not looking.
3. On the front side i plan on putting Entry Level Programmer for a title and doing a bullet list of my skills: C++, C#, Java, XNA, Unity, Unreal Engine, and Hero Engine
Does anyone think this would be a good approach to this??
Show some tact. If you want a job, send a résumé.
If you want a job through networking at a convention, leave people with the impression that you are a confident, stable, self-secure—but not self-centered/arrogant—person who is NOT looking for a job, and then send a résumé, if the contact seems inviting in such a manner.
Giving people the impression you are talking to them only because you are trying to get an advantage towards getting into their companies does not impress anyone, and generally makes them uninterested.
I would rather hire someone who just makes sandwiches, so make it your first priority not to make it known that you are looking for a job, until someone specifically takes the conversation down that road after you have impressed him or her via your general verbal skills, confidence, and knowledge of the field.
