The three practices continuously provide clients
with the latest knowledge and insights
Digital Identity
E-business
• Internet enables services to be reachable via the digital channel and causes
business to engage in digital transformation
• Innopay helps companies to offer digital services and provides strategies to
support their digital transformation process
• Due to place-independent commerce it is becoming a necessity to identify your
online customers
• Innopay works for several collaborative trust frameworks and also helps
organisations to deal with online identification, authentication and verification
processes of their customers
• The maturing Internet and the enduring mobile revolution change contexts of
commerce. Businesses and consumers demand real time services, any place any
time

demands and exploit the opportunities of this new reality
