Many states cook their own soup when it comes to digital ID apps. Often non-transparent and poorly implemented. I therefore propose that an EU-wide implementation of an ID card app be carried out. There, for example, ID, driver's license, health insurance card are stored. In the next step, you can think about other things. The open source community defines valid standards that states must adhere to in their documents. As an example, I would recommend the Ukrainian government app where all documents are stored cleanly via QR code. This can only be a first step to digitize and simplify other things later. There should be two principles: 1. Open source, this is very important and 2. not any special features again, it is simply implemented what already works in other countries
