If your EID card has a photo on it, it has biometrics. The biometrics are the photo and fingerprints (if your country required them). The fingerprints are not accessible to terminals without a government certificate on them, but the photo can be read trivially. You can download one of many apps (ReadID or Regula Forensics are good options) to see what's on the card.

The standard is ICAO 8303 for how the data structures work. It's the same as ePassports. EU cards implement EAC for the fingerprints, which has a whole mutual auth PKI system.
