COVID Certificate Apps - iOS

This project is released by the the Federal Office of Information Technology, Systems and Telecommunication FOITT on behalf of the Federal Office of Public Health FOPH. The app design, UX and implementation was done by Ubique.

COVID Certificate App

COVID Certificate is the official app for storing and presenting COVID certificates issued in Switzerland. The certificates are kept and checked locally on the user's phone.

COVID Certificate Check App

COVID Certificate Check is the official app for checking COVID certificates in Switzerland. The validation is executed locally on the phone and no information of the scanned certificates is saved.

covidcertificate-app-ios's Issues

iOs version on old iPhones deletes certificates

The app deleted all certificates on an iPhone SE. Two questions?
a) are you aware of this issue?
b) is there a way to obtain the certificate back automatically (was obtained using a transfer code)

cheers

Suggestions - Scan Efficiency

I have 2 suggestions regarding scanning efficiency.

First, make QR codes scannable even during the display of the spinner, and green or red checkmark. This makes it possible to scan the certificates of people that pre-emptively self-validate much faster.

Second, remove or significantly enlargen the square on the checking app in the middle of the screen. It gives the users the idea that they must place the QR codes exactly in the square, but since it would be scanned on the whole area, the effect is that the QR code is unnecessarily small and thus even more unreliable to scan.

Covid Check App - Add 2G rule Check

It would be really nice, to see if the checked covid certificate is corresponding to the 2G rule or not.

Now we have to check everytime the certificate itself and this is tedious work, which can be optimized.
In this way it would be much faster. And i think there will be many 2G checks soon.
I was looking in the API but you can't see this information yet.

Passbook Support

It would be great to have a passbook support for IOS Devices such that the Certificate / QR Code can be displayed through the integrated passbook.

Correct Display the Booster Vaccination not as Incomplete

Swiss Covid App shows Booster Vaccinations as Incomplete Vaccinations
in my certificate i have 3 doses of a total of 2 needed.

I expect the same on the android version

Switch phone brightness to 100% when viewing a certificate

Since Covid certificate QR codes are meant to be read by various devices, I think it would be a good idea to have the app switch the phone brightness to 100% automatically when viewing a particular certificate. This would be similar to QR code based ticketing applications, such as the SBB app.

2G+ verification gives ambiguous display

The verification screen for 2G+ returns a very positive and green result, even if a test results still needs to be checked.

This is the result with a certificate of a person who doesn't needs to show an additional test certificate because they have been vaccinated more recently than 4 months ago:

This is the display when a test is still required:

For the average user, the difference is not clear enough, as both of them pop up as green screens. My personal recommendation, although I'm not a designer, would be to have a different color (maybe yellow for warning or blue for info) to be clear that an additional test certificate is still needed. Or one would have to scan a test certificate subsequently for the green checkmark screen.

iOS 15 Health Integration

Will the app support the upcoming iOS 15 feature to store immunizations and test results with the health app?

Booster after Johnson&Johnson does not reset duration

Hi,

getting a booster shot (in my case of Pfizer) after one dose of J&J single dose vaccine does not reset the duration to 1 year after the booster. However, a booster after 2 shots of AZ, Pfizer, Moderna and etc. giving a total of 3 shots does reset the duration to one year after the booster.

As far as I know, getting a booster shot in Switzerland resets the duration to 1 year after it, but I couldn't find anything about getting a booster shot after the J&J vaccine and the rules about the certificate duration.

The vaccination certificates which I used as reference (1x J&J and 1x Pfizer booster/2x AZ and 1x Moderna booster) are both from a foreign country but using the Covid Cert app. The J&J/Pfizer still has the duration as 365+21 days from the original dose of J&J while the AZ/Moderna has it now set as 364 days after the booster dose of Moderna.

Suggestion: Better 2G+ Check-Flow

When checking 2G+ certificate-requirement, if someone presents a valid 2G-certificate, that does not exempt from a separate test-certificate, one has to switch between different modes constantly (check in 2G+ mode, notice that a test is required, then change to "Test" mode, check the test certificate).
My suggestion is to implement another button "Testzertifikat" which would switch to "Test"-mode, and open the scanner, and then display the usual information for test-certificates; and upon clicking "OK" in the test-window, changes back to 2G+ mode.

Mockup:

Authentication for opening the app

Use fingerprint/biometric check to open the app, this helps to verify the owner of the cert.
As backup use code/password

Suggestion: Apple Watch app

It would be great to be able to display the certificate on the Apple Watch including a complication for easy access from the watch face.

Labels in the wrong language

Hi, it seems that even if I have the app in Italian, some labels are still shown in English

Covid Check QRcode Crash App (dos)

Hello,

Small issue, a person could generate a QR code readable by the application (with an invalid signature), with the parameter "dn" containing the value 99999999999999999999999999999999999, the application will crashes each time the QR code is scanned, the problem is also present on Covid Cert but less problematic, indeed a possible scenario (with a bit of social engineering) is that a person creates a QR code with the payload that crashes the application and presents it to a third party (a restaurant for example), The third party can't check the validity of the certificate because the application will crashes at each scan, the third party could let the access to these services thinking that the certificate is valid and that it's a bug of the application. (Scenario maybe extreme but with a lot of chances that it works).

Only tested on IOS

Hoping to have helped ^^

Feature request: Copy transfer code to clipboard

As some systems allow providing a transfercode when registering for a COVID-test, it would help for the following reasons;
also the time to implement should be minimal.

• Prevent the user from switching back and forth to validate the code when manually copying (between app and registation form when doing it on the same device)
• Prevent failed registation attempts (in cases where the transfercode wasn't copied correctly)
• With shared clipboards this could even help if the registration does not happen on the same device

Suggestion: Apple Wallet

It would be amazing if a certificate could be added to Apple Wallet.

Documentation on "Generate transfer code" missing (Ver. 2.0.0)

I find no documentation in the built-in FAQ's in the app for "Generate transfer code", accessed by pressing + in the lower right corner. What does this do?

Limit number of imported certificates, warn users

I have noticed that venues are using the Covid Certificate app instead of Covid Check.

The app should not allow more than e.g. 10 or 20 certificate. Additionally, it should warn users adding more than three:
"This app should not be used to verify certificates. You should only scan your own certificates. Please use Covid Check instead to verify your guests certificates".

info not shown completely

at new 2G/3G the info is not shown completely.
a scrollbar is missing

Covid Apps

Wieso integriert man das neue Zertifikat nicht gleich in die SwissCovid App? Verstehe nicht ganz das jede App einzeln sein muss.

Homescreen widget with Cert QR code

Add a homescreen widget that can show one certificate and for test how much longer they're valid.

Remove the Refresh/Green Checkmark validity indication

Restaurants, fitness centers, etc. use the green checkmark after the refresh to trust the validity of the certificate instead of scanning the QR code. This is insecure however: every "schwurbler" can simply clone this repository and slightly modify the app to always show a green checkmark, regardless of what is shown in the QR code and enter an otherwise off-limit area.

[COVID Certificate Check App]: Suggestion to omit need to click «verify» after switching to app

The current behaviour of the COVID Certificate Check App on iOS is as follows:

1. Open the COVID Certificate Check app
2. Click «verify»
3. Verify certificates
4. Switch to a different app (for example to check some other related information)
5. Switch back to the COVID Certificate Check app
6. You need to start over at step 2 and click «verify» again

In cases where you often have to switch between apps, this extra click quickly feels inefficent and unnecessary.

Suggestion for improvement:

It would be nice if after switching back to the app, one could immediately be at step 3 and verify the next certificate right away.

Transfer Code Expiry too short

Transfer codes expire after 7 days. It seems that local authorities are not able to meet this timeline. Would it me feasible to extend the expiry to 14 days until the processes have been established?

Dark Mode

A simple dark mode similar in theme to the SwissCovid, MeteoSwiss etc. apps would be nice.

2G+ verification mode

Currently, the Covid Check app only offers 2G or 3G verification modes.

Per https://www.watson.ch/schweiz/wirtschaft/802048735-2g-und-homeoffice-pflicht-das-hat-der-bundesrat-heute-beschlossen, we could upgrade to 2G+, but the Covid Check app does not currently show 2G+ in its UI at all — the results look identical for someone who was vaccinated in the last 4 months and someone who wasn’t.

Use regular QR code pattern for Covid certificate light

The Covid certificate light uses a different type of QR code pattern, with smaller dots, making it harder for devices to read. You need better lighting conditions and less movement. I think it would be a good idea if Covid certificate light would use the standard QR code pattern as well and use a different indicator to distinguish itself from the regular Covid certificate.

Light certificate 2G compatible

Will the light certificate be compatible with 2G ?
Actually it's only compatible with 3G.

„Invalid certificate“ verifying EU certificate

I successfully added an EU certificate but it appears invalid.

Suggestion: Widget Support

It would come in really handy to have a widget for showing the certificate on iOS devices.

Localization

I am trying to localize the app in another language not provided by the default code.
Added new localized strings but How It Works page seems that is not using info from localized documents and keep appearing in english.
How can I translated it too?

AT Test Crashes App

When scanning:

https://github.com/admin-ch/dgc-testdata/tree/main/AT#naa-test
https://github.com/admin-ch/dgc-testdata/tree/main/AT#ra-test

the app crashes.

fake Certificate

I'm currently watching SRF and there is a claim about with the fake Covid certificate you can fool the app. Do you have any information about it?

Add new certificate from downloaded PDF certificate

Yesterday I had my second vaccination and I received an SMS that I can download the COVID certificate as PDF from https://be.vacme.ch/. I've downloaded the PDF to my iPhone. As a next step I wanted to add this certificate into your app. I saw that this is not possible, because I can just use the camera to add a certificate. So I need to download it a again on second device and then use my iPhone to add the certificate to your app. Are you serious?

iOS Widget support

It would come in really handy when widgets would be supported to quickly show the certificate.
