How many people made a cash register?

The invention of the cash register is primarily attributed to James Ritty, who created the first mechanical cash register in 1879 to prevent employee theft in his saloon. However, the development of cash registers involved contributions from various inventors and manufacturers over time. Since then, many individuals and teams have worked on improving and modernizing cash register technology, leading to the diverse range of electronic and digital registers we see today. The exact number of people involved in this evolution is difficult to quantify.
