We introduced a new, higher standard for machines in July 2019.
Manufacturers need to transition to this if they want to remain part of our framework. We set out details of our new framework and the action manufacturers need to take in the document below.
Manufacturers often update the software in their machines for a new banknote design or to make authentication improvements. If you are a business owner or operate a machine, you can check you are using the correct version of software or firmware.
We test a sample model only and not every machine that is manufactured. Please be aware of the limits of our testing (these are set out in section 9 of our framework).
