Credit Card Glossary: Terms and Definitions
A knuckle-buster is a manual credit card impression machine that creates multiple receipts by sliding a handle to record the raised numbers on the front of a credit card onto carbon-paper packet copies. The credit card is placed on the bottom of the machine and the carbon receipts on top. The user then slides the handle across the machine and back to make the impression. Also called a zip-zap machine.
