- Facial images are ordinary personal data, so the standard lawful bases suffice on their own.Plausible but wrong: biometric identification data is special-category, so the ordinary lawful bases alone are not enough without an Article 9 condition.

- Special-category processing is always lawful where the employer simply relies on legitimate interests.Plausible but wrong: legitimate interests is an Article 6 basis and cannot by itself satisfy the Article 9 conditions required for special-category data.
- Facial templates are biometric special-category data, barred unless an Article 9 exception applies. ✓Correct: biometric data used to uniquely identify a person is special-category data, whose processing is prohibited unless a specific Article 9 exception plus safeguards apply.
