Generate printout for EU digital certificates #581

Closed Balze2 closed 3 years ago

Balze2 commented 3 years ago

Description

Generate a printout for the stored EU COVID certificates.

Suggested Enhancement

Currently it's only possible to store a EU digital COVID-Testcertificate in the App. It would be a great benefit to print a certificate.

Reason to ask for it: My daugther is going for a scandinavia trip with a group of 18 persons. (14 children, 4 adults) The adults have to take care, that the certificates of each child is available. What if one of the children loose/broke/... its smartphone? It would be a great backup to have a printed version available.

Thanks for taking into account

Internal Tracking-ID: EXPOSUREAPP-8352 obsolete (vaccination DCC) Internal Tracking ID: EXPOSUREAPP-8328 obsolete (test DCC) Internal Tracking ID: EXPOSUREAPP-8384 export function for all DCCs - iOS Internal Tracking ID: EXPOSUREAPP-8900 export function for all DCCs - Android

Currently the following is being considered: PDF can be generated for all types of DCCs with different templates (vaccination, test, recovery) PDF can be generated only for DCCs issued in Germany for DCCs issued by another country, an error message is presented to the user Original EU template used for printing PDF can be shared using the standard OS sharing functionality

@Balze2 I like your idea!

@Balze2

Thanks for your proposal. I have informaed the dev team about it. The developers and RKI will think about your proposal. We will report back here on Github if a decision has been made.

I assume we will see something like this in one of the next releases: https://github.com/corona-warn-app/cwa-quick-test-backend/pull/143 & https://github.com/corona-warn-app/cwa-server/pull/1491

ndegendogo commented 3 years ago

@Ein-Tim do you understand the description of the PR? What does he mean with "show a printable version"?

ndegendogo commented 3 years ago

of course a mobile device cannot print. But instead of showing a printable version I would expect to export a printable version?

Ein-Tim commented 3 years ago

@ndegendogo

The printable version is the QR-Code which is shown in the app on the corresponding template from here: https://github.com/Digitaler-Impfnachweis/certification-apis/blob/master/templates/README.md

ndegendogo commented 3 years ago

Ah - thanks. But how do I then print it?

Ein-Tim commented 3 years ago

@ndegendogo

In German the text in the app is "Druckversion anzeigen", similar to what you can do when creating an Event QR code.

Ein-Tim commented 3 years ago

Ah - thanks. But how do I then print it?

I assume like you can print the QR code from an event at the moment.

ndegendogo commented 3 years ago

So maybe they think "exportieren" is too technical, and the concept of showing it is easier to understand for non-technical people? 😅

jucktnich commented 3 years ago

You can print from an iPhone indeed. Just search for "AirPrint"

Ein-Tim commented 3 years ago

One recommendation: Don't call it "Druckversion" but rather "Zertifikat Exportieren".

iOS PRs reg. this have the milestone 2.10 attached to it, this does not seem to match with the Fix 2.9 label here.

ndegendogo commented 3 years ago

One recommendation: Don't call it "Druckversion" but rather "Zertifikat Exportieren".

😅😅😅

@Ein-Tim Maybe I can display the "Druckversion", then make a screenshot, and export that to my laptop for printing

Ein-Tim commented 3 years ago

@ndegendogo If I understood correctly you will see a preview of the "Druckversion" and then you can share it with the standard iOS / Android sharing menu.

ndegendogo commented 3 years ago

@Ein-Tim sounds good 🎉

idoodler commented 3 years ago

I would appreciate this feature, we are about to depart from Iceland and Iceland Air requires Covid-19 documents, but they don't accept Screenshots of the QR Code, rather then Official Vaccination documents.

So we can't use the online check in, but have to use the personal checkin at the airport

Ein-Tim commented 3 years ago

@idoodler

CWA 2.10 will come with this feature. In the meantime you can use CovPass, there you can create print outs of your EU digital COVID certificates already now.

Ein-Tim commented 3 years ago

Hey @Balze2!

This feature has been implemented in version 2.10, which has been released today.

More information can be found in this blog post: Version 2.10: Corona-Warn-App ready to inform users about booster vaccinations

If you consider your request as implemented, I'd like to ask you to close this issue.

Thank you!

alanrick commented 3 years ago

I can confirm that it works as described on my iPhone. But perhaps someone has the patience to explain to me why this is the best possible implementation.

I’m confused by the text on the pdf generated that states I can import this pdf/paper version into my CWA to obtain a digital version. Why would I want to export a pdf from CWA and then import it into the CWA again?

Surely the qr-code rendering of the cert’s character-string alone is the certificate? The fold-instructions/yellow-graphics etc are simply embellishments irrelevant in determining the legitimacy of the test/Immunity.

My own personal experience was that the different countries I visited that required the EU certificate were satisfied when I uploaded the png rendering of the qr code. And whenever I’ve needed a paper backup a print-out of the screenshot from my Apple Wallet has sufficed.

Bottom line: Is the qr-code alone sufficient, or are the other text graphic embellishments necessary for validation, too? If the embellishments don’t play a role in the legitimacy, wouldn’t it make more sense for the CWA exported version to explain how to validate the paper print-out (e.g. CovPass Check App) rather than how to reimport it?

ps: many thanks to @Ein-Tim for replying to my twitter comments

Balze2 commented 3 years ago

Thank you very much for adding this function to CWA!

Best regards

These things, the text staying to scan the QR code with CovPass or CWA, as well as the fold instructions are only there because the original template is used. What you create in the CWA is the same as you would get when going to a pharmacy with your yellow vaccination booklet and asking them for a certificate.

alanrick commented 3 years ago

But what’s the point in using the same template as the pharmacy? The pharmacy version was generated for people to import the certificate into an app to avoid carrying the yellow booklet with them, but the intention of the generate button is to create a paper backup that can be used when your phones dead/broken. The former is designed for importing, but the latter is intended as a „passport“ to be validated. Different use-case -> different text.

MikeMcC399 commented 3 years ago

@alanrick CWA 2.10.1 generates the standard format EU Digital COVID Certificate for Germany. This is not a special "pharmacy version". It is the one used by all generated papier format versions.

Users can do what they want with this, for example:

It does also include the text "Mehr informationen unter: www.digitaler-impfnachweis-app.de" which contains lots of information in German and English about certificates and their usage.

alanrick commented 3 years ago

I agree you can use the pdf for all this and more. But the problem to solve in this wish-list item was to generate a paper copy to be used as a “green pass” backup where legitimization by non-digital experts is important. I also realise that my gripe would best be solved by improving the German template to explain how the pass can be validated, because without validating this makes a mockery of a beautifully devised EU green-pass system.

So far my passes (paper/app/wallet) have been inspected about 40 times but not even the German Border Control validated it electronically. So an extra educational line of text above/below/within the graphic generated by the template explaining how to validate it would have been cool.

As an aside, the only places that did validate my pass were pubs, hotels and restaurants in Dublin. Digital capital of Europe?

MikeMcC399 commented 3 years ago

@alanrick I understand your point about wanting to improve the text on the templates, however this is probably the wrong place to make suggestions to get it changed.

I'm not completely clear about who controls the template formats which are based on EU guidelines. I believe though that Corona-Warn-App is more or less just a consumer of the template.

If you look in the https://github.com/Digitaler-Impfnachweis/certification-apis/tree/master/templates you can find DCC Print templates (Germany). The CWA community made some formatting suggestions for the template in certification-apis/issues which were picked up and implemented. That repository also hosts discussions.
