Fill in the ASCII code (http://www.scienceoftech.net/Sampling/ASCII.html) for the first three letters of your name (first or last). (This will be the code you cut into the index card and sent through our “bar code scanner”.)

Transfer this code to the form provided.

Cut out the sections that correspond to the “ones” in your code.

Run these codes through the “scanner” and see if you can match the code you hear to the letter represented.
