Identification cards play a crucial role in validating our personal information and identity. Verifying ID cards is a vital step in the user onboarding process for the financial services industry, or any sector that needs to onboard authenticated users.

This is where you can employ ID OCR (Identity Document Optical Character Recognition) technology. This innovative technology automates and simplifies the process of extracting valuable information from identity documents, and other documents such as a passport or driver’s license. So, let’s look into how this amazing and transformative technology works.

What is optical character recognition (OCR)?

ID OCR (Optical Character Recognition) is a technology that enables recognizing and extracting text from digital data sources, images, or documents. Simply put, OCR tech is a software solution that can “read” the textual data from such digital documents and convert it into searchable and editable plain text.

Here is a look at how ID OCR technology works:

Scanning and image pre-processing

The first step is image scanning and pre-processing. In this step, the identity document is scanned using a device like an ocr ID scanner or a camera. This captured image is then pre-processed. This pre-processing involves correcting any distortions or imperfections that may be present in the image. This step is crucial as it determines the accuracy of the OCR software.

Text detection

After the image is pre-processed, the OCR solution uses advanced algorithms to scan, identify, and locate any textual data that may be present in the image. The ‘text detection’ step also involves separating the text data from any images or graphics in the document completely. The current modern OCR software uses AI for the text detection process. They are so capable that they can segment individual characters, even if they are handwritten or are in different font styles.

Character recognition

Now, once the text is located, the OCR software then analyzes each individual character. After that, it converts the character into a digital format like the ASCII code. AI plays an important role here by helping to analyze and recognize characters with a high degree of accuracy – even if they are distorted, skewed, or illegible.


Next, the OCR software moves to the post-processing stage. Here, it corrects any errors or discrepancies that may be present in the document. This includes spelling checking, grammar correction, and even consistent formatting.


This is the final step of converting the extracted textual data into a simple text file or a database. This conversion allows the information to be accessed and edited easily. This makes it ideal for tasks like data entry and document management.

Applications for information extraction from identity document

Having understood the workings of ID OCR, it is important to understand its practical implications. Let us take a look at some of the real-world applications of data extraction using OCR software.

Onboarding users

Several businesses require their customers to provide ID papers during the onboarding process. As a manual task, it can be daunting and overwhelming. However, with ID OCR, businesses can quickly and accurately collect important information like the customer’s name, age, and address directly from their documents. This advancement greatly assists in making the onboarding process much quicker and more effective.

Border control and security

Passport OCR is a vital tool for border control authorities and security agencies for countries across the world. It enables them to scan and verify the information on passports quickly and accurately. This helps ensure the authenticity of incoming travelers and prevents document fraud.

KYC compliance

Know-Your-Customer (KYC) regulations make it mandatory for financial institutions to conduct due diligence on their customers. OCR ID card technology can help in this verification process. It can extract relevant information from the customer’s identity documents and create a database. This makes it easier for such institutions to comply with regulatory requirements.


ID OCR can be used to extract patient information from identification documents. It can help reduce the time and error rates associated with the manual patient registration process.

Law enforcement

Law enforcement agencies like police departments can use ID OCR to identify an individual from their identity documents. This can help them in investigations and preventing identity theft.
