One of today's biggest business challenge is to do not lose the consumer before he becomes a customer only because of treating him wrong in the process of identification, registration, and authentication. Regulations such as the DSGVO and PSD2 increase the pressure on the industry, but also create new opportunities. At the same time, new standards and technologies in the field of authentication, a rapidly growing range of solutions for more efficient KYC processes (Know Your Customer), blockchain IDs and many other developments are providing new instruments to serve digital customers better than ever before. The focused use of new technical options is the basis to be able to serve existing customers perfectly in the digital change and to win new customers with new services by perfectly combining one's own strengths with the opportunities of new technologies.
