In Ohio, USA, James Ritty invented the cash register to prevent his employees from stealing from his saloon. The device was a mechanical counter that recorded sales and had a bell that rang when a sale was made. While the cash register was a success, its early versions were prone to jamming and were expensive. It eventually became a standard piece of equipment in retail, but its initial failure to be widely adopted shows that even successful inventions can have a rocky start.

The cash register is a symbol of the mechanization of commerce and the desire for accountability, a theme that has been explored in poetry and literature as a critique of capitalism. Its invention is often cited as a turning point in the history of retail, and it has been featured in various works as a symbol of the modern world. The cash register's early struggles serve as a reminder that even the most successful inventions can face initial setbacks, a lesson that resonates with poets who write about the nature of progress.
