How to edit a QR code
THE QR code now they are very popular. Not everyone knows, however, that there are mainly two categories of QR: those static and those dynamic. The difference is not visible at a glance, since the appearance – except for particular customizations applied by the user – is almost the same. What changes is the method with which the data associated with the code are encoded: static QRs contain information that cannot be changed over time (as it is incorporated into the code itself).
The data contained in dynamic QR codes, on the other hand, can be subject to variations, as the code contains an external web address. This type of code is ideal for sharing information such as contacts, menus, social pages, and the like, precisely because the data incorporated in them can be easily modified directly in the service they “point to”.
Having made this necessary premise, in this guide I will explain to you how to edit a QR code dynamic, whose data can be changed at any time (without however altering the image relating to the code in any way); finally, I will give you some information about the modification of the QR code related to Green Certification (Green Pass), useful if your health status in relation to the COVID-19 disease changes. Enjoy the reading.
How to edit an existing QR code
Having made the necessary clarifications, the time has come to explain how to create a dynamic QR code, whose corresponding information can be changed at any time, without having to change the code itself.
One of the best services that allow you to achieve this from a computer is The QR Code Generator: it is an application that must be installed directly in the browser Google Chrome, which allows you to create an unlimited number of dynamic QR codes and to view scan statistics for each code.
The service, to which you have to subscribe through a Google account, Microsoft account or email address, can be tried for free for 15 days, after which you must subscribe to a paid plan with prices starting from € 5.59 / month billed annually or € 6.55 / month billed monthly.

If you don’t have Chrome yet, refer to this tutorial to get directions on how to install it on your computer; if you own a Chromebook, on the other hand, you don’t have to install anything, as the operating system Chrome OS it is natively compatible with the “Big G” browser applications.

How to change a QR code: Green Pass
As you certainly know, the Green Pass is a document issued following the completion of the vaccination cycle against the COVID-19 disease, the recovery from the same or the negative outcome of an antigenic or molecular swab for the search for the pathogen related to the same infection.
Depending on your health status, the Green Pass may be suspended or lose its validity: for example, the document issued following vaccination is suspended in the event of a positive result, while the Green Pass issued following a swab “expires” after 48 hours from the sampling for the antigen test, or after 72 hours from the execution of the molecular test.
So, if your Green Pass is no longer valid and you need to change it, you must first get the identification code relating to the event that generates the new certification: AUTHCODE (you receive, via email or SMS, following the administration of a new dose of vaccine), CUN (printed on the result of the molecular swab), NFRE (printed on the result of the antigenic swab) or NUCG (printed on the report issued by the ASL / ATS following the certified recovery from the disease).

Once you have the code, you can download the new Green Pass from the DGC website or through the Immuno app, using the code in your possession and your health insurance card; if you have not received any identification code or have lost the swab report, you can request it via the Web (I explained how to do it in my guide on how to receive the AUTHCODE), download the Green Pass via the app IO or, again, use the Regional Health Record or the DGC website by logging in via THERE IS (Electronic Identity Card), SPID identity or TS-CNS (health card with functions of the National Service Card). To find out more, I refer you to reading my guides on how to apply for the Green Pass And how to download the Green Pass without SPID, in which I explained everything to you in great detail.
