Smart Hospitality
Challenge
The transition to smart hospitality offers significant benefits to both guests and hosts. Guests can receive personalised services, gain easy access to information about the resort and its surroundings, configure room conditions according to their preferences, and enjoy a frictionless and relaxing stay. At the same time, hotel owners and managers can reduce operational and infrastructure costs through energy efficiency, increase guest satisfaction, and benefit from data-driven decision-making. However, implementing smart hospitality raises concerns around security, legal compliance, and data privacy. Tourists are often required to share sensitive personal data during the booking and check-in process—including passports, IDs, contact details, and the purpose of travel—which can be vulnerable to misuse. Ensuring GDPR compliance while delivering customised experiences is a key challenge for smart hospitality providers.
TANGO solutions
This use case focuses on delivering privacy-preserving, personalised experiences in smart hotels and resorts. Using the TANGO platform, guests will benefit from a seamless digital onboarding process before their trip, acquiring a secure digital identity (ePassPort) via their mobile phone. Upon arrival, they can check in using their mobile wallet without needing to present physical documents or credit cards. Room preferences are automatically applied, and guests receive tailored recommendations for activities and services through a mobile application, all while preserving privacy through self-sovereign identity (SSI) and token-based interactions. Hotel room environments are monitored and managed using IoT sensors via the NADIA platform to ensure optimal comfort and energy efficiency. At check-out, guests provide feedback on their stay and receive a personalised report on their carbon and energy footprint. For hotel managers and staff, onboarding also occurs via secure digital identity. Through the TANGO platform, managers gain access to analytics dashboards powered by platforms like EDAE and VIS, offering insights into guest satisfaction, energy consumption, and overall performance. Access is governed through policy enforcement (PEP/PDP) and attribute-based encryption (CP-ABE), ensuring role-based data visibility and security.
Lessons learned and TANGO added value for your case
For the case study of the Smarthospitality pilot, the experience has been very satisfactory, it can speed up the hotel's check-in processes, get to know its customers and room parameters better thanks to IoT, avoid bad references and reduce its costs. However, the current check-in processes and above all the information that the hotel receives from the tour operators about its customers means that the implementation is not sufficiently feasible at the moment. However, with future deployments of data spaces and the integration of all supply chain actors, the system could be of enormous use.
