It makes stuff easy. Great interface and functionality (intuitive and nothing is more than a few taps on screen away). Bit annoying initial setup if you don't have German ID, but that's the price you pay for safety.

I understand my data needs to be secure but why make it so complicated when swapping devices. Now I need an additional app? And the PIN for my ID card? I cannot access anything unless I provide these details. Besides that I have the previous login key, my TK Safe key, sms tan and I don't know what else.... This makes it everything but userfriendly. And there are other methods to make an app safe.

Aufgrund der gesetzlichen Bestimmungen zum Schutz Ihrer Daten ist die App je Versicherter nur auf einem Gerät gleichzeitig erlaubt. Hierzu erfolgt bei einem Gerätewechsel eine erneute Gerätebindung. Diese können Sie auch über den Freischaltcode durchführen, welcher 4 Jahre gültig ist und wieder verwendet werden kann. Freundliche Grüße, Ihre TK-App

Update: the developer replied that the problem is speocifc to one plus phones and there is no way to fix it. This app works like a charm with one exception. When I try to scan a sick note using the camera through the app, it always blurs the image to the extent that no text is visible. They should either fix this issue or provide an option to upload an already captured image.

We are sorry that you are having problems taking a clear picture. This is an individual problem of your OnePlus-camera. We tried to fix it, but there's no way. Alternatively, you can also send your sick note via message to TK. Thank you for your understanding. Best regards, your TK-App Team
