What is a Mechanical Cash Register

Definition and Basic Working Principle

A mechanical cash register is a manually operated till that uses levers, gears, and springs to record sales, calculate totals, and store cash. Instead of relying on electricity or software, these registers work through purely mechanical movement. When a cashier presses number keys and an operation key (like “total”), the system mechanically adds amounts, opens the cash drawer, and prints a paper receipt.

Mechanical registers date back to the late 1800s and were widely adopted throughout the 20th century. For decades, they were the standard in small retail shops, grocery stores, and hospitality businesses. Their durability made them ideal for heavy daily use before digital technology became the norm.

• A UPS (uninterruptible power supply) for short-term backup
• A mechanical cash register as a fallback for processing sales

• Mobile payment processing
• Syncing with accounting software
