France has begun trialling a digital coronavirus travel certificate, becoming the first EU member state to begin experimenting with such technology. The TousAntiCovid app, which has thus far been used as a contact tracing service, can now store Covid test results on customers’ smartphones within the ‘carnet’ (booklet) feature of the app. The TousAntiCovid app will be trialled on flights to Ajaccio in Corsica this week, with Air France and Air Corsica informing their eligible customers beforehand. French citizens who have taken a Covid test will now receive a text or email from the lab with a document featuring a QR code, which can be scanned to upload test results (both PCR and antigen) directly to the app. Those who do not wish to use the app can print out a certificate instead, which also features the QR code. Denmark, too, has begun a trial of its ‘coronapas’, a digital app which stores vaccination records, test results or proof of a previous Covid infection. The European Commission is currently working on a ‘digital green certificate’ to facilitate free movement with the EU that it should be ready for use by the end of June.
