From the inception of AIS, Sine Qua Non has supplied industry leading technology to the market. All our legacy products date back to 1992 in development. As of March 1 2013 We have ceased all production and are concentrating on developing a new product range for 2014. As our initial products were designed long before any formal AIS documentation, our new product range is being designed utilizing the latest AIS input documents thereby meeting new default requirements. Sine Qua Non is an internet only company. ALL communication is via email
