Italian Prime Minister Mario Draghi has signed a decree to create a “green pass”, a digital proof that the holder is not infected by the coronavirus.

The system, which became operational just hours after Draghi signed the decree on Thursday, produces a unique QR code a holder can have on their smartphone to prove they have been vaccinated;that they are immune to the virus after an infection in the last six months; or that they have recently tested negative for the coronavirus.

For those who do not have a smartphone, the certificate can also be printed out, Xinhua news agency.

The system is however, only open to Italian residents, reports xinhua news agency.

The European Union (EU) is set to produce its own version of the “green pass” starting on July 1.

Those certified in Italy will automatically qualify for the EU version of the pass when that system becomes operational.

The “green pass” is part of an effort for Italy to restart its massive tourism sector, which was crippled last year due to the lockdowns tied to the pandemic.

The tourism sector accounted for more than 13 per cent of Italy’s gross domestic product (GDP) in 2019, according to the data firm Statista.

But in 2020, that figure dropped to barely half of the normal levels amid the pandemic, just 7.0 per cent of the country’s diminished GDP.

The new “green pass” is open to all residents of Italy who can qualify based on health status, even those who are not part of the country’s national health system.

Registration is available without cost, and the forms are available in Italian, English, French, and German with other languages likely to be added in the future.

To be eligible based on health status, an individual must have had their first vaccine dose at least 15 days earlier, their second dose at least two days earlier, the same day as a negative test result, or within one day of being declared recovered from Covid.

The certificate will remain valid for nine months after the last vaccine dose, for 48 hours after a negative test, and for six months after recovery.

The pass will be required for attending large gatherings, and starting on July 1, will be valid for quarantine-free travel within the EU.

The scheme goes into effect during a period when the country’s main coronavirus indicators are showing a dramatic improvement, and while the country’s vaccination program is working smoothly.

In the last 24 hours, Italy recorded 1,325 new coronavirus infections with 37 deaths, which increased the overall caseload and fatality toll to 4,249,755 and 127,190.

Both figures are broadly in line with recent days.

The indicators have steadily decreased since the most recent peaks in March, when the number of daily infections was regularly over 20,000 with more than 300 deaths.

Italy has so far administered more than 44 million vaccine doses, and 14.8 million people, the equivalent to 27.3 per cent of the country’s population aged 12 or older, have been fully inoculated.
