Validator Instructions: Step Into Digital Identity - One Selfie at a Time!

Feedback Quality Policy

We expect feedback to be complete, correct, and specific. Please follow these guidelines:
  1. Select all applicable rejection comments for each image using the blue rejection comment box next to it;
  2. Use the rejection comment checkboxes in the bottom section of the job only if the comment applies to the entire job (Guide for Validators, section 2.2 “Rejecting the job”, p.12)
    3. Click on the line starting with sign for more detail.
    Examples:
    • The rejection comment “Age must be +12”can usually be applied to the entire job, provided the same person appears in all photos;
    • The rejection comment “You are only allowed to wear your glasses in the first selfie” can be applied to the entire job only if the user is wearing glasses in all photos;
    • The rejection comment “Requested changes were not made” can be applied to the entire job only if none of the changes requested by the previous validator were implemented.
    Exceptions:
    If you:
    • selected "Block Clickworker" (see Rejection and Resubmission Policy), or
    • marked job as "Spam",
    then no rejection comments regarding the photo quality are required.

Rejection and Resubmission Policy

  1. If at least five images need to be redone, provide detailed feedback on all images and select "Discard job";
  2. If a user uploads authentic but inappropriate content (e.g., nudity, violence, substance abuse), select “Block Clickworker” and “Mark job as suspicious”, and use the rejection comment: “Inappropriate content.”

PII Policy

The media submitted by users must not contain any personal information they did not consent to share, such as their name, address, phone number, tax number, social media account, license plate, etc. Additionally, personally identifiable information (PII) of other individuals - including visible faces - is not allowed.
📌 Only the participant should be visible in the submitted photos. No other faces (e.g. people, TV screens), depictions of human faces (e.g. posters, comic books), or human-like figures (e.g. statues, toys) should be visible. Users are allowed to crop their photos, but the final image must maintain good visual quality.
1. Scanned Document Photo Check
In this section, the user is asked to download a specific mobile app, scan their NFC-enabled givernment ID, and upload the headshot photo extracted from the chip.
Our goal is to confirm that the uploaded file is an authentic scan from the chip, made using the app.
1.1 Media Info Requirements
  • "Resolution in MP" must display 0 MP;
  • Minimal width is 240px;
  • There should be no additional EXIF data, such as the "Created at" timestamp or the camera brand/model.
1.2 Authentic Scan vs. Screenshot
If the image is a face photo from an ID but contains watermarks, reflections, or signs of a screen capture, then it was not extracted from ReadID Me app.
Incorrect: a close-up photo of a German National ID card taken with a phone camera
Correct: an ID photo extracted from the ID card's NFC chip using ReadID app

Ensure that the document's issue date is earlier than its expiration date. Expired documents are acceptable, provided they are not older than 10 years from the current date.
