Who Makes QR Codes: The Company That Starts It All

QR codes are everywhere. They’re on products in stores, posters at bus stops, and even business cards. But who makes QR codes? And how did they become so ubiquitous?

Who Makes QR Codes?

DENSO WAVE is a Japanese company that specializes in the design and manufacture of barcode and RFID products. The company was founded in 1976, and its headquarters are located in Agui, Aichi, Japan. In 1994, DENSO WAVE announced the release of its QR code. The QR in the name stands for Quick Response, expressing the development concept for the code, whose focus was placed on high-speed reading.

Today, DENSO WAVE’s QR codes are used in a variety of applications, including product tracking, time tracking, and document management. QR codes are also becoming increasingly popular as a means of marketing and advertising, as they can be used to link directly to websites or social media pages. There are many different companies that make QR codes, but DENSO WAVE is considered to be the original inventor of the technology.

How Do QR Codes Generate?

QR codes, or quick response codes, are scannable barcodes that can be read by smartphones. When scanned, a QR code can display text, images, or even website URLs. QR codes are often used to provide quick and easy access to information. For example, a QR code might be placed on product packaging in order to provide customers with additional product details. 

Or, a QR code could be used to share a special offer or coupon with potential customers. QR codes are generated using an online QR code generator. This tool allows users to input the data that they want to be encoded in the QR code. Once the data is entered, the generator will create a unique QR code that can be printed or downloaded for use. When scanned, the QR code will display the encoded data on the scanner’s device.

How Much Information Can a QR Code Hold?

A QR code is a two-dimensional barcode that can be read by a smartphone camera. QR codes are often used to provide website links, contact information, or other types of data. But how much information can a QR code actually hold? QR code is capable of handling all types of data, such as numeric and alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes.

Up to 7,089 characters can be encoded in one symbol. A QR code symbol of this size can encode 300 alphanumeric characters. That means a QR code has the potential to provide a lot of information in a small space. QR codes are becoming increasingly popular as a way to share information quickly and easily. 

Can Anyone Create a QR Code?

There are many free QR code generators available online. To find one, simply do a search for “QR code generator” in your favorite search engine. When choosing a QR code generator, you’ll want to look for one that allows you to customize the code design, as well as choose what type of data you want to encode. 

For example, some generators will let you create a code that opens a specific website when scanned, while others will let you generate a code that stores your contact information. Once you’ve found a generator that meets your needs, simply follow the instructions on the site to create your QR code.

Can Someone Copy Your QR Code?

Anyone can scan your QR code using a smartphone or another device with a camera and an internet connection [1]. However, only you can change the content that your QR code points to. This is because each QR code is generated using a unique string of characters that can only be accessed by the owner of the QR code. For example, if you create a QR code that links to your website, only you can change the URL that the QR code points to. 

This means that even if someone tries to copy your QR code and use it for their own purposes, they will ultimately be directing traffic to your website. In other words, they will be helping you – not hurting you – by copying your QR code.

Do QR Codes Expire?

QR codes are a type of barcode that can be read by devices with a camera, such as a smartphone. When a QR code is scanned, it opens a Quick Link that takes the user to a specific website or other online content. Because QR codes do not have an expiration date, they can be used indefinitely as long as the Quick Link behind them remains active. 

Quick Links are automatically generated when a QR code is created and remain active unless they are deleted or archived. This means that as long as the site or content that the Quick Link points to remains active, the QR code will continue to work.


To sum it up, QR codes are a type of barcode that can be read by smartphones and other devices. They are used to store information such as website URLs. QR code generators allow you to create your own QR codes. And finally, no one can copy your QR code unless they have access to your QR code generator’s dashboard.
