Having a good business card can help you maintain contacts, promote yourself and your business, and make friends. By creating a personal business card that involves the recipient actively translating your card will make him more likely to remember you and share your card.
Remembering the decoder rings and my fascination with secret messages I thought I could make an interesting business card that could not only tell a story, but give useful information on how to contact me. I did this first using just a block out grid stencil, and secondly with a QR code acting as the grid.
This is the fun part. You can be creative here and write a fun story or any sort of document. A bit of spam perhaps, or something that describes your work. That is one of the more interesting things you can do with a decoder business card. Rather than worry about cramming all your contact info along with something that describes what you do. You can add both!
Make sure to include all the characters you want decoded. I started with a "B" because I wanted the first part of my name to show up on the upper left.
