Starting June 5, 2024, the UK introduced new banknotes featuring a portrait of King Charles III. To keep up with these changes, it's essential to update your bill counter software. A bill counter software upgrade involves updating the internal software that recognizes and processes banknotes. This upgrade ensures your bill counter can accurately detect and validate the new security features embedded in the latest currency. Without this update, your bill counter may fail to recognize new banknotes, leading to potential delays and errors in cash handling.
