What is a QR Code?
Have you ever seen a strange square pattern with a bunch of black and white squares inside? It may seem like a random design, but that is actually what we call a QR code. Yes, those square codes that you see everywhere these days, from product packaging to movie posters. But what exactly is aQR codeand how does it work?
To put it simply, QR code stands for Quick Response code. It is a two dimensional barcode that was first introduced in Japan back in 1994 by Denso Wave, a subsidiary of Toyota. At the time, it was used for tracking parts in vehicle manufacturing but has since evolved into something much more than that.
So, how does this technology work? Well, QR codes are scanned using either a smartphone or a specialized QR code reader. When you scan the code using your phone's camera or the reader, it translates the patterns into data which then directs your device to perform an action.
The matrix of small squares within the QR code holds the encoded data which can range from URLs to text messages and even WiFi network information. This makes QR codes incredibly versatile and convenient as they can hold more information than traditional barcodes.
One of the main benefits of QR code technology is its ease of use. With just one scan, you can access various types of information without having to type out long web addresses or search for specific apps on your phone. It also saves time as you don't have to manually input any information.
Another advantage is its cost effectiveness. Generating and printing QR codes is relatively inexpensive compared to other forms of marketing materials such as brochures or flyers. This makes them accessible for businesses of all sizes, making it an efficient tool for marketing and advertising.
How does a QR Code Work?
Data Encoding: A QR code can store different types of data, including text, URLs, contact information, or other types of information. The data is encoded into the QR code using a pattern of black squares arranged on a white background, allowing for high-speed scanning and decoding.
Scanning: To read a QR code, you need a QR code scanner, which can be a built-in feature on a smartphone's camera or a dedicated QR code reader application. When you point the camera at the QR code, the scanner captures the image and decodes the information embedded within the code.
Decoding and Interpretation: The QR code scanner decodes the pattern of black and white squares and interprets the encoded data. This data may include a website URL, text, contact information, or any other information that the QR code creator intended to convey.
Action or Display: Once the QR code is decoded, the device may perform various actions depending on the type of information stored in the code. For instance, if the QR code contains a URL, the device may automatically open the corresponding website in the browser. If it contains contact information, the device may prompt the user to save the contact details. QR codes can also be used for making payments, displaying text, directing users to specific content, or initiating other specific actions based on the encoded data.
Scanning With a QR Code Reader
Scanning a QR codewith a QR code reader is a straightforward process that can be easily done using a smartphone or a dedicated QR code scanning application. Here's how to scan a QR code using a QR code reader:
Install a QR Code Reader App: If your smartphone doesn't have a built-in QR code scanning feature, you can download a QR code reader app from the app store. Popular QR code reader apps include QR Code Reader by Scan, QR Code Reader by ScanLife, or other similar applications available for both iOS and Android devices.
Open the QR Code Reader App: Launch the QR code reader app on your smartphone by tapping on the app icon.
Align the QR Code: Position your smartphone's camera in such a way that the QR code you want to scan is within the viewfinder of the camera.
Scan the QR Code: The QR code reader app will automatically detect the QR code within the camera's viewfinder and capture the image. You might see a visual indication or hear a sound to confirm that the QR code has been successfully scanned.
View the Result: Once the QR code is successfully scanned and decoded, the QR code reader app will display the information embedded within the QR code. This information may include a website URL, contact information, text, or any other data that the QR code was designed to convey.
Take Action: Depending on the type of information stored in the QR code, you can take appropriate actions. For example, if the QR code contains a website URL, you can choose to open the website in the browser. If it contains contact information, you can save the contact details to your device's address book. If it's a text message, you can view the text on your screen.
