It can be easy to start looking at a business card as some kind of creative project that you would want to pour all of your aesthetic abilities into, but you should remember that this business card is mainly supposed to fulfill a functional purpose at any given point in time. A big part of the reason why that is the case has to do with the fact that you would not be showing these cards off at some kind of an art gallery, much on the contrary you would mainly use them at conventions where you are attempting to market your enterprise.
That means that the information you put on Metal Business Kards should be your top priority in some way, shape or form. Suffice it to say that there are some basic bits of data that every card should have, such as your name. However, it is also really important to not let the ball stop rolling there. Your name is not enough if you want your business card to have any sort of impact, so you should also add your designation so that anyone that gets your card will have a good enough idea about the role that you play in your organization.
Finally, there is the all important addition of contact information. Some people keep this to a work phone number, but it can also be immensely useful to add other modes of contact such as an email address. Most people would not want to give you a call right off the bat, and offering an email address gives them a less socially intensive way to get in touch with you all in all.
