From academic certificates to lab reports, counterfeiting has become a worrisome issue across industries. And given the advancements in softwares such as Photoshop, forgery has become easier.
This can mean a loss of revenue and identity theft for the concerned stakeholders. So how do we stop this? Well, there’s one way you can conveniently do the needful in an effective way—via QR Codes.
QR Codes are 2D barcodes that can store a lot of information. You can scan them via a smartphone or a dedicated app.
These square-shaped barcodes are ubiquitous today. And you might have seen them at the check-out counter in grocery stores for payments or on print media creatives.
These QR Codes can be used extensively for identifying fake documents. In this article, we will show you how QR Codes can help in document verification.

A. Why use QR Codes for document verification
With QR Codes, you can identify whether any given document is genuine or not. It’s even better if you have your own database or own information system that can help the end users verify the document details. Here is how it works:
You create a QR Code that links to your website or database containing all the details of the required documents. These may include details such as name, document identification number, and license details.
When the end-users scan the QR Code on the physical document, they will be able to see all the details on the phone. These details can then be matched with those on the printed document.
Since the details will be hosted on your information system, none will be able to tamper with them.
B. Popular use cases of QR Codes for document verification
Here are some ways you can use QR Codes to prevent forgery:
1. Certificate authentication
You would have come across some duplicated certificates (academic degrees or even licenses). And it is tough to spot the difference between an authentic and a forged copy with a mere look.
But QR Codes are up for the game. How? If you issue certificates to your students, customers, or any other stakeholders, just add a QR Code to them. Now this QR Code would be linked to all the details on the document on your own website or database.
As people scan it, they will be able to see all these details on the web link. In addition to the details, this QR Code may also show the status of the document such as Valid or Invalid. It’ll help easily verify the document’s authenticity without having to match every detail in the database manually.
2. Laboratory reports
Laboratories issue health certificates throughout the day. And since the pandemic, report authenticity verification has become important to curb disease spread.
Now just like the use case mentioned above, QR Codes can offer an effective way of verification here.
