ID Card Checker

Check identity documents such as ID cards and passports for the accuracy of their machine-readable zone.

You are a police or customs officer, working in a bank, managing door security at a club, or renting out cars and bicycles and have to deal with identity documents daily?

Then download the ID Card Checker to your smartphone or tablet!

The ID Card Checker helps you evaluate the machine-readable zone of identity documents for accuracy and detect potential red flags.

The machine-readable zone of an ID or passport is produced according to the ICAO 9303 standard. It is generated from the personal data in the visual inspection zone. ID Card Checker calculates the mathematically correct check digits from the underlying data and compares them with the numbers in the machine-readable zone for accuracy.

Supports all ICAO document types:
• TD1 (e.g., credit card sized ID cards, 3 lines)
• TD2 (e.g., official identity cards, 2 lines)
• TD3 (e.g., passports, 2 lines)

★ Free Features:
✔ Manual verification of check digits for date of birth and expiration date
✔ Visual OCR-B font reference with comparison examples
✔ Examples of identity document counterfeits and incorrect zones
✔ Demo of the Pro feature Expert Mode

★ Pro Features (via In-App Purchase):
✔ Expert Mode: Complete verification of all MRZ fields (serial number, date of birth, expiration date, optional data, and total check digit)
✔ Fast Camera Scan: Capture identity documents directly with your camera – no manual typing needed
✔ Includes initial scan credits (additional scan packs available flexibly via in-app purchase)
✔ Ad-free experience

It also provides an overview of the digits used in the OCR-B font, including counter-examples. This template gives you the opportunity to visually compare the printed numbers with the OCR-B standard.

The app shows examples of fake identity documents and incorrect machine-readable zones.

The ID Card Checker was developed with advisory support from detectives and is available in over 190 countries to check identity documents.

★ Privacy and data protection are our highest priority:
Your data and any checked document details remain entirely yours. All calculations and image processing during camera scans happen 100% locally on your device. No personal document data or camera images are ever transmitted to external servers or stored permanently on your device.
