Download QR Code Scanner: The Ultimate App for Scanning and Generating QR Codes
QR Code is a two-dimensional version of the barcode, typically made up of black and white pixel patterns. Denso Wave, a Japanese subsidiary of the Toyota supplier Denso, developed them for marking components in order to accelerate logistics processes for their automobile production. Now, it has found its way into mobile marketing with the widespread adoption of smartphones. "QR" stands for "Quick Response", which refers to the instant access to the information hidden in the Code.

The first QR code system was invented in 1994 by the Japanese company Denso Wave, a Toyota subsidiary. They needed a more accurate way to track vehicles and parts during the manufacturing process. To achieve this, they developed a type of barcode that could encode kanji, kana, and alphanumeric characters.
The development team behind the QR code wanted to make the code easy to scan so that operatives did not waste time getting it at the right angle. They also wanted it to have a distinctive design to make it easy to identify. This led them to choose the iconic square shape that is still used today.
Initial uptake of the idea was slow; however, in 2002, the first mobile phones containing built-in QR readers were marketed in Japan. The use of smartphones led to an increase in the number of companies using QR codes.
In 2020, Denso Wave continued to improve on their original design. Their new QR codes include traceability, brand protection, and anti-forgery measures. There are many new uses for the QR code, from transferring payments to determining objects' positions within augmented reality.
Attackers can embed malicious URLs containing custom malware into a QR code which could then exfiltrate data from a mobile device when scanned. It is also possible to embed a malicious URL into a QR code that directs to a phishing site, where unsuspecting users could disclose personal or financial information.
A typical attack involves placing malicious QR codes in public, sometimes covering up legitimate QR codes. Unsuspecting users who scan the code are taken to a malicious web page which could host an exploit kit, leading to device compromise or a spoofed login page to steal user credentials. Some websites do drive-by downloads, so simply visiting the site can initiate a malicious software download.
A QR reader can identify a standard QR code based on the three large squares outside the QR code. Once it has identified these three shapes, it knows that everything contained inside the square is a QR code.
The QR reader then analyzes the QR code by breaking the whole thing down to a grid. It looks at the individual grid squares and assigns each one a value based on whether it is black or white. It then groups grid squares to create larger patterns.
QR codes can be used for multiple purposes, but there are four widely accepted versions of QR codes. The version used determines how data can be stored and is called the "input mode." It can be either numeric, alphanumeric, binary, or kanji. The type of mode is communicated via the version information field in the QR code.
3. Maxi code - This type of QR code is used by the United States postal service. It's similar to the Aztec code in that it places the finder pattern in the middle, but it uses a honeycomb pattern instead of squares.
4. PDF417 - Invented in 1991 by Ynjiun Wang of Symbol Technologies, the oddly named PDF417 predates the QR code by three years. It looks like a mix between a QR code and a barcode and is easily recognizable by its rectangular shape.
They can also be used to link directly to product pages online. For instance, if you were searching for the exact dress a model was wearing in a poster, a QR code could directly take you to the web page where you could purchase it.
The coronavirus pandemic has supercharged the use of QR codes. For example, in the UK, visitors to hospitality venues such as bars and restaurants are invited to scan a QR code upon arrival using the NHS Covid-19 tracing app. This is to help trace and stop the spread of the virus. If someone tests positive for Covid-19 at that venue, other visitors to the location are alerted by an app, thanks to the data accumulated from QR code scans.
You may also find QR codes on the packaging for some of your favorite products. These QR codes can reveal information about the product, such as nutritional information or special offers you can use next time you make a purchase.
QR codes were initially invented to help track parts in vehicle manufacturing, and they are still used throughout the manufacturing industry. You'll also find QR codes used by other businesses that need to keep a close eye on products and supplies, such as the construction, engineering, and retail industries.
Postal services around the world also use them. Because they can contain a large amount of information, they are often relied upon to track parcels. For example, global fashion brand ASOS have moved entirely to QR codes for tracking refunds.
QR codes are also used in schools and colleges to help engage with students. They have appeared everywhere, from the classroom to the library, for tasks such as helping students find the books they are searching for.
