Download the buyer’s guide to document verification software.

The demand for online services and products is increasing at an unprecedented rate. With this shift to adopting online platforms, it becomes vital for businesses to confirm the identity of their customers via an online portal.

Online Document Verification is imperative for businesses to ensure safety, eliminate misuse of services and render better customer experiences.

For example, ride-sharing apps need online document verification to ensure both the rider and driver are identified as real individuals. Online document verification is important to fight online identity theft and make online experiences safer.

Let’s dive into the guide to document verification and learn more about it with illustrative examples.

What is document verification?

In a traditional setting, the original ID card or passport was the way to verify an individual’s true identity. But in an online setting, online document verification is crucial to building trust amongst the target audience.

Document verification is the process of verifying the authenticity of a document.

Document verification is used to check the originality of submitted documents, extract information using OCR software like Nanonets, and match genuine microprint text to match identities.

There are many official documents that can be verified by using a document verification software like Nanonets:

  • ID card
  • Passport
  • Driver’s License
  • Bank Statement
  • Utility Bill
  • Tax bill
  • Insurance Agreement
  • Employment documents
  • Educational Documents
  • Employee Letters & many more

The verification process checks document features, such as stamps, watermarks, holograms, fonts,  or other security features, and automatically approves the document. This automation saves time and effort for the organization and frees up employees’ time to provide better services.

What are the different ways to verify identity documents?

Check that the security features are in the right place

Every ID document has unique security features, such as watermarks, logos, holograms, and microprint. Checking that these security features are where they are supposed to be is a solid first step in verifying the document is real. All that is needed is a clear image of the document to be able to verify its security features.

The result should be a clear, horizontally aligned document image.

Compare the ID data for consistency.

Every ID has the document holder’s data encoded in some way – whether in a barcode or a Machine Readable Zone (MRZ). Any mismatch between this data and the data printed on the rest of the document ( its so-called  Visual Inspection Zone, or VIZ) indicates tampering.

Match the user’s face with the portrait on the document

Another way to verify a document is to compare the ID photo and the uploaded selfie of the customer. If the characteristics of these two images match, the user is the genuine owner of the submitted document.

What is the Document Verification Process?

Now, the next question is, how do you verify documents? Let’s deep dive into 4 steps of document verification and see how we can automate it.

Step 1: Document Data Capture

This is the step where you collect documents to verify. You can ask the end users (customers, employees, vendors, or more). Here, you also make documents ready for the next step. The pre-processing document includes checking the borders of the papers, de-skewing the images, and improving the color and brightness of the image to ensure better data extraction at the next step.

You can use Nanonets to collect documents automatically using multiple document import options.

Also, Nanonets can deskew, enhance contrast, and automatically check for blurry images, text, and more.

Step 2: Data Extraction

We must extract data from documents to verify it in the next step. You can use OCR software, like Nanonets, to remove relevant information and discard the rest.

Document Data Extraction : Nanonets vs others

Instead of a simple OCR software, it is better to use Nanonets as it converts your entire document into a structured document.

At this step, you can also classify the document based on its document structure. Check out the document classification model on Nanonets.

Step 3: Document Validation

Now, you need to validate the data. You can use database matching to perform this action. You match data from documents with data from a trusted database.

For example, the loan processing department might want to check if the person applying for a loan has any present loans in the same bank.

Document validation is imperative to reduce identity theft and fraud.

Step 4: Verify documents with a manual check

As a final step, any flagged documents can be sent for manual review through approval workflows. This is a human-in-the-loop document verification process. This ensures there are no errors.

After checking for everything, the documents are then verified.

You can automate this entire process on Nanonets using approval workflows.

Future for document verification

The document verification market is growing at a rate of 14.4% CAGR, and there is a reason for that. Businesses are moving their processes online, which includes document verification too. Additionally, there is a sharp increase in the databases where customer data is stored.

In order to ensure that only “real” customers access the online data, businesses must regularly verify identity. Using manual methods will not only slow the process but will also make the process error-prone, costly, and insecure.

Document verification automation will be a boon for businesses of all sizes to ensure secure access to data, services, and products.  Nanonets help businesses automate manual document processes. We have helped many organizations like Toyota, P&G, and EY, digitize their manual processes with no-code workflows, which has resulted in cost & time savings.

What are the challenges of using online document verification?

Here are some of the disadvantages of using online document verification.


Document verification software is a powerful tool to verify fraudulent documents but it is not exactly foolproof. Human in-the-loop verification is a must for all regulatory institutions to prevent mistakes. 

Inefficient & Expensive Identity Verification Solution

There are many ID verification solutions available in the market. Each has its own advantages and disadvantages. Also, each has its own protections against fraud, but some are more easily forged or tempered with than others. Companies are constantly updating techniques in order to meet growing data privacy needs across countries and industries. It is crucial to look at their security certifications. 

Evolving Biometry Forgery

The rise of technology has given birth to the problem of online identity verification. For every advance in identity verification, there is an advance in identity fraud techniques. Detection techniques for each type of biometric forgery are required, as well as proactive monitoring of the involving fraud techniques.

Hurdles in Determining the real identity

Document verification software checks for the authenticity of the document and forged documents. But if the fake ID passes all the verification filters, it would be difficult to identify the person without manual verification processes. 

What are the benefits of using online document verification?

Businesses reaping a fair share of success due to their growth and appeal of ideas need to tackle the complex web of fraudsters who’re ever-present at their cyber portals. Employing AI in ID verification increases the security of commercial portals ten-fold, along with providing businesses with an edge over those who’re on the lookout to commit fraud. When used in conjunction with human intelligence, AI increases the human ability to process data, thereby enabling businesses to process information intelligently and prevent being scammed. Some of the benefits that machine learning brings to document verification are:

Faster return on investment

Automation document processing tools can be set up and trained in days or weeks rather than months or years. With a lower total cost of ownership, enterprises can apply automated document processing to a wide range of documents to realize ROI faster compared to traditional tools. Softwares like Nanonets can provide up to 3-5x ROI in less than 3 months. Learn more 

Improved operational flexibility

AI with deep learning enables rapid document modeling and training so that new, never-processed documents can be quickly added to the document processing system.

Faster operational responsiveness and compliance transparency

AI-led automation can support “human-in-the-loop” validation that delivers document classification and extraction results to the person submitting the document. This enables fast and responsive information verification and correction in near-real-time. Front-line workers can quickly make corrections or request additional information while collaborating with customers, partners, or other external stakeholders. This saves time and ensures better data accuracy and transparency for everyone involved in a business process.

Enhanced Fraud Detection

AI-enabled document processing software can detect fake documents by using photoshop, EXIF or forgery detection. It keeps a check for any anomaly in the documents which can indicate tampering of any sort.

Scalable processes

Document verification software automates the entire document verification process, making it standardized and scalable across geographies without any differences.
