  • FlexyPay App - Ultra Dynamic and Diverse Payments (Development)

    I built the FlexyPay App as a highly dynamic and secure solution for handling mobile payments and facility access. It is an app that embeds all the powerful features of FlexyPay in an easily accessible and understandable mobile interface. One of its major areas of use has become unmanned stores. End users authenticate using the app and are either granted or denied access to the facility. When they are done and want to check out, they can use the app to pay for the goods that they picked up.

    Because of the powerful identification features of FlexyPay, the store owners can feel confident in the visitors behaving as they should.

  • FlexyKey - Future of IoT (Development)

    With the rise of 5G, microcomputers, and modern smartphone technology, IoT is becoming more and more a reality. Having the flexibility to read and control devices from a remote location dramatically improves interconnectivity and flexibility within many sectors of business, research, and, in the end, people’s daily life.

    Combining these concepts with modern smartphone apps, directly available in everyone’s pocket, allows for highly efficient and convenient services.

    I have, together with FlexAccess, developed a technology called FlexyKey, where efficient micro-hardware is combined with smart technology through a mobile app service.

    The FlexyKey hardware allows web- or GSM-based controlling of up to 64 different electronic devices in a single unit. It’s a generic, flexible unit that supports a wide range of devices, such as vending machines, doors, gates, car washes, and golf carts, to name a few.

    With simple adjustments, it can be adapted to almost any kind of system.
