Which challenges do we want to tackle?

CHALLENGE 1: Biometric Authentication


How can we take advantage of biometrics in order to increase security and enhance user experience during digital transactions, as well as in homes, cars and other infrastructures?

In an increasingly digitized world, securing information and protecting our data is becoming more important than ever. At the same time, customers are becoming more accustomed to immediate and seamless experience in digital transactions and other day-to-day activities. As a result, large companies seek to leverage the advances in biometrics to find unique and more effective methods that guarantee the security of operations and users’ personal data, while facilitating their daily life.

CHALLENGE 2: X Reality


How can we improve business processes and customer service by taking advantage of visualization technologies?

The strategy of any corporation is centered on optimizing production and operational processes as well as bringing value to the market through its products and services. To achieve these objectives, it’s necessary to ensure a remote connection between various systems and to show processes, products, and services in a realistic and immersive way. Doing so can simplify production and supply chain activities for employees in addition to providing clients with optimized support throughout the entire customer journey.

CHALLENGE 3: Smart City


How can we leverage the connections between systems and the data gathered by our network of urban infrastructures to offer new products and services to citizens in real time?

The rise of smart technologies and technological systems integrated into urban infrastructures results in generating a large amount of user data. In order to differentiate from the competition, large corporations must find new ways to collect and utilize this data not only to offer new products and services, but also to improve the users’ experience according to their current and future needs.

CHALLENGE 4: Circular Economy & Sustainability


How can we take advantage of the circular economy solutions in order to contribute to sustainable development and promote the use of renewable energies?

The transition to renewable energies is continuously accelerated by technological advances and changes in the consumption habits of users who increasingly prefer sustainable and ecological solutions. Large corporations are also involved in this process and seek to contribute to environmental protection by improving their production, maintenance and recycling processes according to the principles of the circular economy. To continue these efforts, it’s necessary to develop new products and services that promote the use of renewable energies, helping to optimize our natural resources and achieve the zero-waste goal.
