Employee ID badge data redaction is the removal of identifiers from a card scan or staff roster. UK GDPR Recital 51 says a photograph is not automatically special-category data, and Art. 4(14) treats a face as biometric data only once it is processed by specific technical means to identify someone uniquely. anonym.plus marks names, pass numbers, and contacts on your device.
When this applies
The line matters in practice. A photo pass shared as an image sits outside Art. 9(1), but feed the same face into a recognition system at a turnstile and the template it produces is biometric data needing an Art. 9 gateway. Either way the picture identifies the holder, so an export to a partner or a contractor should carry neither the face nor the pass number.
How anonym.plus handles it
- Open the card scan or roster in anonym.plus on your device.
- Local OCR reads names and numbers printed on it.
- The tool flags names, pass numbers, and contacts.
- Review the photo area and black it out.
- Swap or black out the confirmed items.
- Save the clean copy locally.
What you need to provide
- The card scan or roster (image, PDF, or DOCX).
- An operator (Redact suits a photo pass).
- Optional batch for a roster export.

Compliance achieved
- Follows the line UK GDPR Recital 51 draws: a photograph is not automatically special-category data, yet it still identifies the holder.
- Recognises Art. 4(14), under which a face becomes biometric data once processed by specific technical means for unique identification.
- Helps keep an access system out of Art. 9(1) territory where no recognition template is created from the image.
- Applies data minimisation under Art. 5(1)(c) to a roster export that needs a head count, not a pass number.
- Local OCR reads printed card text, and batch mode covers up to 20 files per run.

Limitations & cautions
A face can re-identify a worker even when every text field is masked, so black out the picture area too. The tool flags printed items; it does not judge whether your access system creates a biometric template from that image.
Frequently asked questions
Is a staff photo special-category data?
Not by itself. Recital 51 says photographs are not automatically caught, and Art. 4(14) brings a face into scope only when specific technical means process it for unique identification, as in facial recognition.
Does the tool remove the photo?
Use Redact to black out the photo area. The tool flags printed text, while you cover the face so it is hidden.
Can it clean a whole roster export?
Yes. Batch mode handles up to 20 files per run, with OCR for printed text.
