What is a QR Code?

QR Codes, also known as Quick Response Codes, are two-dimensional barcodes that store information within a series of squares and dots. These codes are used to encode a variety of data, including product information, website URLs and even contact information. Companies can use them to promote their products or services by providing customers with easy access to their websites or physical stores. By simply scanning the code with their smartphones, users can quickly get relevant details about the product they’re interested in or locate the nearest store.

Because of its quick response time and easy accessibility, QR Codes have become increasingly popular among businesses in recent years. Businesses can take advantage of this technology by placing these codes on their products or advertisements. Customers will be able to quickly get all the details they need about a product or service without having to type anything in. This can significantly shorten the customer journey and make it more efficient for them.

In addition, QR Codes provide another layer of security for businesses as the codes are difficult to replicate and only contain encrypted information that is readable by scanners. Therefore, businesses can be sure that their customers will receive accurate and up-to-date information every time they scan a code. Furthermore, since these codes are customizable, businesses can add branding elements or logos to further increase their brand recognition and visibility.

Overall, QR Codes offer a number of advantages for both business owners and consumers alike. By making use of this technology, companies can make their products and services more accessible to customers, while also providing a secure and efficient way for them to access relevant information. By leveraging this tool, businesses can be sure that their customers will have a seamless experience when interacting with their brand.

Simplified Example

A QR code is like a secret message written in a special language that can only be read by a certain type of camera. Just like how a treasure map has special symbols that tell you where the treasure is hidden, a QR code has special symbols that take you to a website or give you information.

Who Invented the QR Code?

The term "QR Code" was introduced by Masahiro Hara, an engineer at Denso Wave, a Japanese automotive products company. In 1994, while engaged in a project aimed at tracking automobile parts, Hara envisioned a barcode that could be swiftly and easily scanned while accommodating more data than conventional barcodes. The resulting QR Code, a two-dimensional barcode featuring a square grid of black and white squares, was designed with a specific pattern for interpretation by QR Code scanners. These scanners decode the pattern, converting it into data that serves various purposes, such as product identification, shipment tracking, or website access.


Mobile payment QR code: Retail stores and merchants can generate a unique QR code for each transaction. Customers can scan the code using their mobile banking app, which will then initiate a payment transfer. This method eliminates the need for physical cash, checks, or card transactions and speeds up the checkout process.

Event Ticket QR code: Event organizers can create QR codes that serve as electronic tickets. Attendees can simply scan the code at the entrance to the event to confirm their ticket and gain entry. This method reduces the risk of lost or stolen physical tickets and makes it easier to manage entry and exit tracking.

Contact Information QR code: Business cards with a QR code can be scanned by smartphones to quickly and easily add a new contact to their phone's address book. The QR code can be programmed to store various contact information such as name, title, email address, phone number, and more. This eliminates the need to manually enter information and makes it easy to share contact information with others.
