Snowfish® Quality Control

Ultimate tool for Quality Control of new banknotes - to be launched at HSP Latin America Conference, June 2018

IGT and PNO Global co-operate in the production, sales and services of the range of ‘Snowfish®’ products. Mr. Tom Buitelaar, former Dutch National Bank (DNB) and European Central Bank (ECB) employee, invented the ‘Snowfish®’.
