QR codes, or Quick Response codes, are two-dimensional barcodes that can be scanned using a smartphone or other device equipped with a camera and a QR code reader app.
They were originally developed by Denso Wave, a subsidiary of Toyota, in 1994 for use in automotive manufacturing, but they have since been widely adopted for a variety of other applications.
Here’s a fun fact about QR codes:
Did you know that the largest QR code ever made was created in 2013 in China? The code was made up of 1.5 million colourful Lego bricks and measured 31 meters by 31 meters (approximately 101 feet by 101 feet). The code could be scanned using a helicopter-mounted QR code reader from an altitude of up to 500 meters (approximately 1,640 feet). The massive code was created to promote a new shopping centre in the city of Ningbo.

Here are some examples of how QR codes can be used:
- Marketing and Advertising: QR codes can be used in print and digital marketing campaigns to direct consumers to a website, social media page, or other online content. For example, a restaurant might include a QR code on its menu that leads to its online ordering system or a discount offer for a future visit.
- Event Management: QR codes can be used to streamline event check-in and ticketing processes. Attendees can scan a code on their mobile devices to gain entry to an event, and event organizers can use QR codes to track attendance and gather data on attendees.
- Product Packaging: QR codes can be used to provide customers with additional information about a product, such as nutritional information, product specifications, or instructions for use. For example, a QR code on a bottle of shampoo might lead to a video tutorial on how to use the product.
- Education: QR codes can be used in educational settings to provide students with access to additional resources, such as online readings, multimedia content, or interactive quizzes. Teachers can include QR codes in textbooks or on classroom materials to enhance the learning experience.
- Contactless Payments: QR codes can be used to facilitate contactless payments, allowing customers to pay for goods or services without physically handling cash or credit cards. For example, a restaurant might include a QR code on its bill that customers can scan to pay using a mobile payment app.

- What is a QR code?
A QR code, or Quick Response code, is a two-dimensional barcode that can be scanned using a smartphone or other device equipped with a camera and a QR code reader app. The code contains information that can be quickly and easily accessed by the user.
- How do QR codes work?
QR codes work by encoding information in a matrix of black and white squares that can be read by a QR code reader app. When the user scans the code with their device’s camera, the app decodes the information and displays it to the user.
- What can QR codes be used for?
QR codes can be used for a wide variety of purposes, including marketing and advertising, event management, product packaging, education, and contactless payments.
- How do I create a QR code?
To create a QR code, you can use an online QR code generator tool like the one at qr-code-generator.com. Simply enter the information you want to encode in the code, customize the appearance of the code if desired, and generate and download the code in a suitable format.
- Can QR codes be customized?
Yes, QR codes can be customized with logos, colours, and other visual elements to match a brand or to make them more visually appealing. However, it’s important to ensure that the customization does not interfere with the readability of the code.
- How do I scan a QR code?
To scan a QR code, you’ll need a smartphone or other device with a camera and a QR code reader app installed. Simply open the app and point the camera at the code. The app will automatically recognize and decode the code.
- Are QR codes secure?
QR codes themselves are not inherently secure, as they can be easily copied and reproduced. However, they can be used in conjunction with other security measures, such as encryption, to enhance security.
- Are there any limitations to using QR codes?
One limitation of QR codes is that not all devices have QR code reader apps installed, although many smartphones come with these apps pre-installed. Additionally, QR codes may not be suitable for all types of content, as the amount of information that can be encoded in a code is limited by its size and complexity.
- Are QR codes still relevant today?
Despite being developed over 25 years ago, QR codes remain a popular and versatile tool for a variety of applications. With the rise of mobile devices and contactless technology, QR codes are likely to remain relevant for the foreseeable future.
