Which technology is commonly known as 'knuckle-busters' for imprinting credit card data on cards?

• A. Travelers checks
• B. Imprinters
• C. Credit card verification books
• D. Knuckle-busters

Answer: (B)

Manual imprinting uses a card imprinter to transfer the embossed card numbers onto carbon paper, creating a physical receipt copy. This device earned the nickname “knuckle-busters” because merchants had to press hard on the handle, often bruising knuckles, to force the impressions. That tough, hands-on action is why the term sticks to the device. So the best answer is the card imprinter, the technology used to imprint credit card data. The other options don’t refer to a device that performs imprinting: travelers checks are a payment method, credit card verification books aren’t used for imprinting, and while knuckle-busters is the nickname, the formal term for the technology is imprinters.
