Images of toys, dolls, dogs and cats, for example, that our children used to love for years would jump into our eye even when we are placed in heavy pressure and caught in severe panic, meeting any need of identity assurance in any demanding situations.

The aim of our enterprise is to make Expanded Password System solutions readily available to all the global citizens: rich and poor, young and old, healthy and disabled, literate and illiterate, in peace and in disaster.
