The abacus is the original mechanical counting device. It was likely first used over five thousand years ago, and used beads to keep track of numbers.

A mechanical counting device is a tool designed to tally or count objects or events using mechanical components rather than electronic systems. These devices often utilize gears, levers, and dials to increment a count each time an action, such as pressing a button or pulling a lever, is performed. Common examples include tally counters and odometers. They are typically simple, reliable, and do not require electricity to operate.
An abacus.
A mechanical counting machine is a device used to count items or currency accurately and efficiently. It typically consists of rotating gears, levers, and dials that increment with each item counted. These machines were commonly used before the advent of electronic calculators and are still used in some settings for tasks like tallying votes or counting money.

The counting device invented after the abacus is the calculating machine, with notable examples including Blaise Pascal's Pascaline in the 17th century and Gottfried Wilhelm Leibniz's stepped reckoner. These early mechanical devices were designed to perform arithmetic operations automatically, significantly advancing computational capabilities compared to manual counting methods like the abacus. The development of these machines laid the groundwork for modern calculators and computers.
