A unique security system for transactions

A digital system of printing notes' numbers and counting information on DVR systems.
Tracking and recording notes' receipt and purchase for the clients, linking the client's picture, purchase time and notes' numbers, so the records if the transaction can be presented to the client.
For example, when a client complains about purchasing a note where this system is installed, the system can show the transaction, including the client's face and the numbers of the notes sold to or purchased from that client.
This system is specifically designated to Newton 3 machines.
