Sigma 100

The Sigma 100 was created as an entry level cash counting machine for sole traders and small chains and quickly became a very popular solution. The Sigma 100 was an affordable solution for small businesses who required the time and money saving benefits of the more advanced machines in the Cashmaster range without paying for extra features they didn’t require.

The Sigma 100 has since been replaced with the Sigma 105 but many are still being used today. Below you can download the quick start guide, view a training video or see our FAQs.
