Offline digital euro payments hinge on secure chip tech in smartphones, ECB says

The future of offline digital euro payments hangs in the balance as the ECB struggles to secure agreements with smartphone manufacturers.

The European Central Bank may drop offline digital euro payments if it can’t agree with smartphone makers on secure chip integration. In a digital euro progress report published on Dec. 2, the central bank has emphasized that secure elements — specialized hardware chips embedded in mobile devices — are essential to ensure offline transactions can be conducted safely and reliably.

The ECB detailed ongoing discussions with device makers and technical service providers to overcome the complexities of deploying offline digital euro solutions. However, without consensus on implementation, the project might eventually face potential delays or a complete scale-back.

“Due to its highly controlled environment, deploying an application remotely is complex and involves multiple stakeholders.”

While the ECB is exploring digital euro features, without agreement from tech partners its offline use could potentially be limited. Thus far, it remains unclear whether the offline feature will advance or stay as a conceptual idea given that the challenge isn’t unique to the eurozone.

For instance, Sweden’s Riksbank, in its latest research report, also highlighted the technical and regulatory hurdles for enabling secure offline payments with the e-krona, the country’s proposed central bank digital currency.

The Riksbank warned of liquidity risks stemming from unsynchronized balances between offline and online wallets, creating potential usability and security issues for recipients of offline transactions. To mitigate such risks, Riksbank suggested solutions like restricted offline usage or centralized liquidity pools but acknowledged these require further evaluation.
