The QR code
In today's world, technology is key, and scanning high volume of 1-Dimensional barcodes is a high priority in many industries, whether it be because of verification purposes or the total number of items and tasks that need to be completed within a time limit to facilitate smooth process flow.
When referring to 1-Dimensional barcodes, the one type that instantly comes to mind are the standard one-dimension codes that can normally be seen everywhere, whether it is on food packages, products, other components, or even on rack labels for storage purposes in large warehouses.
These simple one-dimensional barcodes often have issues with becoming damaged and unreadable, can only hold a very limited number of characters, and must be scanned from precisely the correct direction.
As this can be imagined, this all adds up to a slow-going process for everyday work revolving around inventory management and information tracking within warehouses and other industrial facilities. However, incorporating a different type of barcode (2-dimensional barcode), called the QR code, makes scanning process much easier and faster to those who rely on barcodes for gathering information.
The QR Code technology is becoming increasingly common and present in our everyday lives.
You may have come across block square dots or lines on many document papers or even on smartphone screens. Those are called QR codes. Now let's delve into these square dots and lines, and find out what they offer.
In this guide, we'll explore the fascinating world of QR Codes, and provide a guide for those getting to know about this wonderful technology. We'll answer basic questions like "What QR Codes are", "How they work" and "How to use it" , as we explore the many applications that make QR Codes currently so popular.
QR Codes have the power to transform the way we interact with the world around us. Whether to access additional information, make instant payments or even contact people and companies more efficiently, these two-dimensional codes offer a universe of possibilities. Throughout this guide you will get to know how to decode a QR Code and it's implementations in different aspects. Also, we will explore how a QR code can be used to authenticate document information, so you can have the clear knowledge and make the most of this technology. Get ready to harness the power of the QR code and enhance and simplify your document issuing process. Now let us dive into the world of QR code and find out how it can transform the process of document authentication and verification.
QR code stands for "Quick Response code", it is a two-dimensional barcode. It encodes alphanumeric information. To decode this information, you can either use a handheld scanner or even a QR Code scanning application on your smartphone. Many smartphones now have an in-built QR Code scanning feature in their stock camera application. If you look at a QR Code, you’ll see black-colored squares (or dots) all over it.
These are called data modules. The information you add to the QR Code is stored in these data modules. Hence, every module (black or white unit block) or a string of modules either represents data or a function. Scanners read these data modules to decode the information stored in them to reveal the stored data.
The QR code was invented in 1994 by Masahiro Hara, head engineer of Denso Wave, a Japanese firm and subsidiary of Toyota, and it was first used to track automobiles and parts as they traveled through the production process. Unlike traditional barcodes, which can only be read top to bottom, they contain information as a sequence of pixels in a square grid that can be read in two directions: top to bottom and right to left.
The QR code have the capacity to hold an astounding amount of information, up to 7,089 digits or 4,296 characters, including punctuation and special characters. It may also encrypt data. Each QR codes' layout varies based on the information it contains, affecting the design of its black modules.
The data structure of a QR code comprises duplicates, guaranteeing that even if the code is 30 percent damaged, it will still be legible by a scanner. The ability to scan from any angle, and at a longer distance, and with a higher rate of accuracy, means that those using this code will have the information they need to get their task done efficiently and effectively.
This is especially relevant when speaking about document verification and inventory management as those are integral parts of security and functional production process, which means accuracy and speed matter.
Types of QR codes
QR codes are classified into two parts. This part is dependent on whether or not the user is wanting a code that can be changed as new information is acquired. They are called static and dynamic QR codes.
Dynamic QR codes are useful for information and data that changes constantly. This normally come with a larger code printed on the material since there would be a lot of information, but dynamic codes have the ability to redirect the user to a URL address. This in turn can keep the code small on packaging, which is useful in terms of cost savings and integrating the code onto products for many facilities.
The next aspect of how these types of 2D barcodes work is the fact that there are forty versions of them that can be chosen from. The smallest code, version one, has 21 modules. Modules are the smallest element on a QR code, which are the individual black and white squares that make up the code. Every version after version one increases by four modules per side, making version forty have 177 modules on each side. Now, as the version size increases, so does the amount of information it can hold.
On the other hand, static QR codes are ones that cannot be updated once the code has been generated. The information is permanently fixed and canot be modified, which makes the use of static QR codes perfect fit for document authentication.
How QR Codes Work
QR Codes work in different ways, but one very common aspect is through a scanning technology. When using your smartphone camera or a specific application for reading QR Codes, you point the device at the code and scan it. The device decodes the information contained in the QR Code and performs the corresponding action, such as opening a web page, playing a video, sending an email, adding an event to the calendar or even making a payment .

There are four different encoding modes that a QR code has access to in terms of storing information. Those are:
QR Code Document Authentication
Having a unique QR code on a document makes it easier to verify. Once scanned, the encoded data within the QR code is compared with the information stored in a secure database.
A match confirms the document's authenticity and a mismatch indicates potential fraud. Plus, it's so fast that the process is almost instantaneous!
In essence, using a QR code for document verification eradicates the painstaking manual verification process that is both time-consuming and prone to errors.
With this, using QR codes for document verification is becoming a preferred strategy for many. Let's get to see more about this unique operation.
Document verification, particularly that of invoice, certificates receipts, Identification cards and laboratory reports, is of the utmost importance today. A single discrepancy can lead to serious consequences, from missed opportunities to legal issues. Let's examine why QR codes are taking the center stage.
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.
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.
Importance of using QR code for Document Authentication
Document authentication is a key concern. Whether we're talking about business documents like invoices, receipt, sales order or academic/professional certifications, or health documents, ensuring their authenticity is paramount.
Previously, verifying document's authenticity used to be a tedious task involving letters, phone calls, emails, and even potentially waiting for snail mail responses!
With a unique QR code on a certificate, the verification process becomes hassle-free and instantaneous.
There's no doubt the importance of document authentication and the role that QR codes play in facilitating this crucial process is hard to overstate.
Benefits of QR code on document authentication
