Not that anyone thinks our Austrian neighbors have better chip passports than our Dutch neighbors:
When reading the passports on an official reading device, the data can be eavesdropped on by third parties from a short distance with relatively modest effort and then quite easily decrypted.
The electronic data that can be captured corresponds to the [name, date of birth, place of residence, etc.] noted in the passport in writing, but the passport photo is also included in the form of a JPEG.
Well, we will probably have a lot of fun with the idiotic tags in passports in Germany in the long run ...
