Designing a business card might sound like the sort of thing that anyone can do in their free time, but suffice it to say that it brings a lot more challenges than your lack of experience would allow you to visualize. To put it plainly, there are simply too many moving parts associated with business card design for you to take it lightly. For example, even if you have put a massive amount of effort into optimizing the visual appeal of your card, you might end up forgetting about the all important question of what information it should be presenting to the world.
At the end of the day, a business card that you can have Metal Kards print out for you will only ever be as important as the information that is displayed on it. The first and arguably most important piece of info that your card should include is your name because of the fact that it is meant to enhance your personal brand. Secondly, it might be rather useful if you incorporated some type of contact information on the card. Your phone number would be the best thing to add due to the reason that people can use it to just call you directly instead of having to jump through any annoying hoops.
These are just some of the things that business cards are supposed to have. A phone number and a name will be more than enough to cover the basics, but you should also recognize the significance of things like branding and the name of your company. Around four to six pieces of information are considered to be critical to the standardized design of business cards and you would do well to keep this in mind.
