From your correspondent in NL
The Dutch app seems to be working OK.
You can also go to https://coronacheck.nl/en/ and print a QR code (for use in NL or for international travel) based on being vaccinated, having recovered from Covid, or having a recent negative test. Or you can call them and they'll send you a QR code in the post. The QR codes can be verified by an app: https://coronacheck.nl/en/scanner
The QR code for use in NL is accompanied by human-readable info: your initials, and your day and month (but not year) of birth, so a venue can check your ID and verify that the QR code matches you, but the QR code or printed certificate does not reveal any further info. The QR code for international travel is linked to more details about your vaccination, etc.
So far, so good. What's not so good is that you used to get the QR code immediately after your second vaccination (or first, for the Jansen vaccine). But it takes two week to develop protection. That and some other issues have unfortunately led to a Covid surge, primarily among young people going clubbing, or coming back from holidays with an unwanted viral souvenir :(. Fortunately that's not really putting people in hospital - so far. The PM and Minister for Health have issued a grovelling apology and are right now being grilled in Parliament about relaxing the measures too far.
