ID – Croatian ID Card Validity Verification

How to check a Croatian ID 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!

Use cases

• Recruitment and onboarding
  When you need to validate a candidate’s identity before signing an employment contract, online verification of an identity document ensures that documents are compliant and limits the risk of fraud. You save time in your administrative procedures and offer a smoother experience to your future employees.

• Real estate rental
  When signing a lease, you can require the verification of proof of identity to validate the tenant’s seriousness. This step ensures that the document provided is authentic and that the information (name, date of birth, etc.) has not been altered or falsified.

• Process KYC (Know Your Customer)
  In the banking or financial sector or for service providers subject to anti-money laundering and anti-fraud obligations, identity validation is an essential element. The MRZ reading and verification of security keys make it possible to comply with the regulations in force while simplifying checks.

• Registering for an online service
  Whether it is for access to a gambling platform, online trading or any other service requiring proof of majority or advanced authentication, the automatic verification of the identity document makes it possible to quickly verify that the user meets the legal requirements.

  In some partnerships or commercial contracts, proof of identity may be required to ensure the identity of a partner or legal representative. Automated ID verification helps secure transactions and builds trust between parties.

How does Croatian ID card validity verification work?

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, 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.

How is the Croatian identity card MRZ gang constituted?
