Company description

Start-up from Vienna dedicated to the topic of payments, specifically mobile payments, and has developed an end-to-end complete solution.

The application focuses on the complete digitalization of the payment process: on the one hand, no physical payment card is needed (it is „tokenised“, i.e. encrypted) and no physical payment terminal on the other. This highly developed solution is extremely easy to use for the merchant and the consumer and considerably lowers the barrier for entry to digital and mobile payment, therefore promoting financial inclusion and suggesting for individual, local payment solution – for all geographies.

Our solution is at par with the industry solutions, like Apple Pay or Google Pay © – but independent from them. The system can be run and implemented by anyone. No bank or financial services license required. It’s running on >90% of the smartphone devices worldwide.

We bring mobile payments to emerging markets in southern hemisphere like Africa and east Asia.
