Presentation
The ambition behind the digital Euro is clear : Combine convenience of digital payments with cash-likes features A key component of this is enabling offline payments, which presents both opportunities and challenges. To explore this, Worldline developed a prototype for the European Central Bank (ECB) to test the feasibility of offline transactions. In this session, IDEMIA and Worldline will share their experiences and findings from this innovative initiative.
The implementation of offline payments in retail CBDCs presents both significant challenges and essential benefits.
Challenges include ensuring robust security and privacy in transactions without online verification, which is critical to prevent fraud and unauthorized access. Developing reliable, secure hardware or software solutions that can function without an internet connection is technologically demanding. Additionally, creating a universally accepted offline payment system requires infrastructure upgrades and compatibility across diverse devices and platforms. There's also the issue of maintaining transaction limits and monitoring for compliance with financial regulations, all while offline.
Despite these challenges, the importance of offline payment capabilities in CBDCs cannot be overstated. They enhance financial inclusion by providing access to digital payments in areas with limited internet connectivity, thus reaching underserved populations. Offline functionality also ensures transaction continuity during network outages or in emergencies, supporting resilience in payment systems. Moreover, it offers a level of convenience and privacy for users, promoting broader adoption of CBDCs. Ultimately, developing robust offline payment solutions is vital for a resilient, inclusive, and widely usable CBDC ecosystem.
