You have provides some good, practiacl information about designing & printing business cards.

Many people would never consider many of your points.

Hers’s another trick that I think is worth mentioning.

The back of any business card is valuable real estate & rarely used.

Why not have your companies points of difference presented as the prime reasons to do business with you.

For examples, Here’s 5 Reasons Why You Should Use Printing for Less for All Your Printing Needs.

Then have 5 bullet points with the reasons.

This also works well in reminding the person handing out the cards, of their company benefits.

I hope you found my suggestion interesting.

Cheers,
Peter
