Over the decades, technology has accelerated its course. One of its significant developments is the invention of QR codes. These codes were initially designed to perform high-speed component scanning but have become a substantial entity of the global economy. They are now widely used at many shops, businesses, contracts, trade for packaging, cashless payments, packet tracking and much more.

QR codes have gained impetus due to their fast-paced data reading, scanning and being able to contain 4000 characters. These codes offer a dynamic range of applications to executives, students, traders and are quite facile to use. Moreover, they provide the users with a sense of high security to their businesses, property, and documents.

Limitations of Normal QR Codes (risks involved):

Though QR codes are the main road to legitimate scanning, they are also at a high risk of being manipulated by unlawful sources.

  1. Harmful websites / embedded malicious URLs:Many times, the browser fools the user exploits in various websites. Therefore, it is always advised to check the entire URL of the websites. These exploits can lead to DDOS attacks, enabling microphone, accessing camera and browser data.

  2. Phishing:The attackers always look to send fake login pages to the users to gain personal information and passwords. This term is also coined as QRishing. As many websites attach QR codes to their online posters, the fraudsters are clever enough to put fake signs instead. Thus, compromising the users’ systems.

  3. Malware:The malware does silent work in the background and thus appear unsuspicious until investigated thoroughly.

Key Differences between Normal QR codes and VeriDoc Global QR codes:

  • The ruling detail that differentiates VeriDoc Global QR Codes from Normal QR Codes is its paramount Blockchain technology after a QR code is scanned. This makes the system immutable, incorruptible, self-patchable, self-expandable without negligible points of failure.

  • Normal QR Codes point to client-server configurations that may arise confusion, distortion, and demand high maintenance. In comparison, VeriDoc Global QR Codes point to systems leveraging a decentralized network configuration where the data is stored as blocks on every node connected to the network. This expanding of the network makes it tough to target or alter.

  • Moreover, the unique hash technology makes it harder to hack the system as they would need multiple computers to mess with the data. These hash values are equivalent to the fingerprint and DNAs present in a file. Therefore, no two hash values can be similar ever.

  • If the document witnesses any big or small change, the hash value is designed to change at that very moment. This cryptographic algorithm is the supreme play behind VeriDoc Global QR codes.

Critical Benefits of VeriDoc Global QR Codes:

VeriDoc Global is a one-stop solution for supply chain, identification, specializations in pharmaceuticals, passports, etc. and has interactive APIs.

Trusted point of reference: It has also diminished the possibility of putting watermarks on trusted documents as they can be easily photoshopped as the original. As an absolute alternative, this patented technology now embeds a unique QR code on the document that is linked to a unique hash value.

Blockchain as the critical technology:The cherry on top is the blockchain network installed in the system. The hash linked to the QR code is allocated to this network to go through security/verification checks and end-term user validation. This analysis forms the basis of verification.

Provides security and transparency:In recent times, many QR code verification solutions rely on centralized servers which create a vulnerability in people’s profiles. These servers have slow networks, meek firewalls, and since all data is stored in a single place, hackers can fabricate a fake document and exchange them with the original.

This also has a possibility of the entire data being lost. If powerful malware is put down into the server, the whole ecosystem will fail. This can only be prevented with blockchain technology which is one of the key benefits offered by VeriDoc Global.

How VeriDoc Global QR Codes work:

VeriDoc Global QR Codes can be scanned by readily available QR code scanning apps or even a standard mobile camera (for some models of android and iOS) on their smartphones.

This anti-fraud document verification system lets the verifier authenticate that a document is genuine by:

Using the camera, hold your phone and place it over the QR code given on the document. Once the scanner identifies the hash, it then compares it to the hash that was recorded on the blockchain network as well as a hash comparison to the original document in real time. Once the digital verification process is complete, the scanner will then show the original document on our mobile screen to do a final visual comparison check. The operation might appear intricate, but the user experience is seamless.

Effective for youth:This is beneficial for school or college students as they quickly become prey to petty document thefts. These codes are also an effective tool for them to verify any source while applying for exams, performing cashless payments, clever logins or even find solutions and resources by scanning the codes given on books.


QR codes hold great potential as they are being used by WhatsApp, WeChat, Instagram, Snapchat, and other prominent platforms to ease interactions for their users with a higher security wall hooked to it. According to multiple 2018 and 2019 sources, QR codes have seen a growth of 28% and have increased the number of interactions by 26%.

These statistics precisely display the confidence users have put in QR codes. With VeriDoc Global QR Codes, this confidence is set to rise. The blockchain technology solution that VeriDoc Global entails is a tangible way to tackle counterfeits and fraud in any online task. This solution has stood the test of time and have been tried by many companies and users to bridge their authentication gaps, fight fraudsters and secure their verification processes.
