ID Card Checker4.0 - Google Play

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

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.
