How to check a French identity card online?
Many business or personnel processes require the presentation of proof of identity: recruitment, rentals, KYC processes, etc.
Nowadays, the pieces are usually scanned or photographed before being sent by email: therefore, it becomes complex to ensure that these pieces are authentic and have not been modified with image processing software such as Photoshop.
Our product addresses this issue and makes it possible to extract information from the MRZ tape of identity documents directly online, analyze it and verify the security keys that ensure its authenticity.
And this in a few seconds!

How does the MRZ online French ID card stripe reader work?
After validation of your purchase, you will receive an email with the credentials to connect to our identity web application (check in spam a few minutes after purchase if you have not received the activation email).
Access to the platform
You log in to the web app using the credentials you receive by email after your purchase or registration.
Selecting the Verification Mode
From your dashboard, you choose the option “Verify an identity document”.
Downloading the document
You import the scan(s) (front and back) of the ID, as an image (.jpg, .png) or PDF.
No additional handling (cropping, rotating, etc.) is required: the system automatically detects the orientation and MRZ area.
Automatic Scan
The service reads the Machine Readable Zone (MRZ) tape and verifies the security keys.
It checks the essential information (card number, date of birth, expiry date, etc.) as well as the integrity of the document via check digits.
Instant result
The results of the analysis are immediately displayed in the interface as a status (passed/failed) and a detailed report (PDF, JSON or XML).
The report specifies the recognized fields and the validity of each element (control keys, date consistency, etc.).
Download and archive reports
You can download or view the PDF report directly.
The data remains available in the history for future reference, but you have the option to delete it at any time (privacy guarantee).
Optional Integration (API)
If you have a CRM or ERP, you can use the API to automate the verification: the document is then forwarded to the department and the report (or just the status) is sent back to your internal software.

Example:

How to verify ID with the MRZ ID card strip?
A machine-readable zone, or machine-readable zone, is an area on an official document reserved for reading, identifying and validating the document.
For example, documents such as passports, French national identity cards, residence permits and driving licenses can or must include an optical reading zone, depending on the country and version of the document.
It is located at the bottom of identity documents: it contains all the information on the document, with security keys to check that it is authentic and has not been altered.
The information it contains varies according to the type of document.
What is the MRZ ID card strip made of?
Cards issued between 1995 and 2021 feature two lines of text, each containing alphanumeric characters.
For detailed information, please consult our article at the following address: Secure file – Checking the MRZ band on an ID card.
Why use this method to verify identity card online?
The data found there is the card data protected by multiple validation keys, making it difficult to modify them. It is therefore one of the verification tools used by airport aviation security to ensure that identity documents have not been falsified.
