MRZ Verification for Required Documents in the Online Check-in – Duve

Duve now offers a new MRZ(Machine Readable Zone)Verification feature to enhance the document upload process for online check-ins. This feature ensures that guests upload valid, verifiable documents, aligning with compliance requirements in countries like Germany. By using AI-powered MRZ (Machine Readable Zone) verification, this update adds an extra layer of security and reliability to the check-in process while simplifying the workflow for both hosts and guests.

In order to process and approve that the MRZ is valid, Duve uses the following:

Character Set:
- Only uppercase letters (A-Z), digits (0-9), and filler character <.
- Composed of 2 lines, each with 44 characters - TD3 format (used in passports)
Check Digits test:
- Check digits are small numbers added after key details like the document number, birth date, and expiry date. They are made using a simple math rule and help spot mistakes if the information was copied or read wrong.
Formatting Rules:
- Personal names use < as a separator or space replacement.
- Dates follow the YYMMDD format.
- The entire MRZ must match the expected length (44 characters per line).
Data Consistency:
- There is no difference between the written data and the data in the MRZ characters

How to Set It Up

Navigate to Settings > Check-in > Required Documents in Duve. Enable the "ID Verification" toggle.

If you want this step to be mandatory, enable the Make Step Mandatory option. This will remove the “Skip” button for guests during the check-in process.

Monitor Verification Status:

- View verification results (Passed/Failed) directly on the Reservations Page, Single Reservation Screen, and Tasks Page in Duve.
- If verification passes, the document ID will automatically sync with the PMS.

Notifications:

When MRZ Verification is turned on, hosts will get notifications by default in the Activity Log.
