Easy Credit Card Number Boxes

It’s easy to create a row of boxes for inputting credit card numbers on a form:

Just use the ballot box glyph from the Webdings font, and then apply negative tracking to the boxes, so that their left and right edges overlap without doubling up. In QuarkXPress, use -12 in the tracking field in the Measurements palette. Be sure not to justify the line though, because that will spread the boxes out.
