These include commercial tracking, entertainment and transport ticketing, product and loyalty marketing and in-store product labeling. They can also be used in storing personal information for use by organizations.
Many of these applications target mobile-phone users via mobile tagging. Users may receive text, add a vCard contact to their device, open a URI, or compose an e-mail or text message after scanning QR codes.
They can generate and print their own QR codes for others to scan and use by visiting one of several pay or free QR code-generating sites or apps.
Google had an API , now deprecated, to generate QR codes,  and apps for scanning QR codes can be found on nearly all smartphone devices.
QR codes storing addresses and URLs may appear in magazines, on signs, on buses, on business cards, or on almost any object about which users might want information.
This act of linking from physical world objects is termed hardlinking or object hyperlinking. QR codes also may be linked to a location to track where a code has been scanned.
QR codes have been incorporated into currency. The coin can be scanned by a smartphone and link to a special website with contents about the historical event and design of the coin.
When scanned with an internet-enabled mobile device, the code goes to a website which tells the centenary story of Nigeria. It contains a QR code into its design, and when scanned with an internet-enabled mobile device, the code goes to a website that details the historical and technical background of the commemorative note.
In , the Bank of Ghana issued a 5-cedis banknote to commemorate 60 years of Central Banking in Ghana, and contains a QR code in its design, which when scanned with an internet-enabled mobile device, that code goes to the official Bank of Ghana website.
Credit card functionality is under development. It will also have the capability of accepting payments on the unified payments interface UPI platform.
QR codes are used in some augmented reality systems to determine the positions of objects in 3-dimensional space. QR codes can be used on various mobile device operating systems.
These devices support URL redirection , which allows QR codes to send metadata to existing applications on the device. Many paid or free apps are available with the ability to scan the codes and hard-link to an external URL.
URLs aided marketing conversion rates even in the pre-smartphone era, but during those years faced several limitations: The chances were high that they would forget to visit the site later, not bother to type a URL, or forget what URL to type.
Semantic URLs decreased these risks but did not eliminate them. With the advent of smartphones the issue of viewers not being able to access a website immediately has become less of an issue, however the trouble of typing in URLs still remained and thus QR codes were utilised in order to allow redirecting to URLs for instant access.
During the month of June , according to one study, 14 million mobile users scanned a QR code or a barcode. QR codes can be used to store bank account information or credit card information, or they can be specifically designed to work with particular payment provider applications.
There are several trial applications of QR code payments across the world. QR codes are commonly used in the field of cryptographic currencies, particularly those based on and including Bitcoin.
QR codes can be used to log into websites: Authentication is performed by the smartphone which contacts the server.
Google tested such a login method in January PSK ; dynamic user credentials i. Order of fields does not matter. As of January , iPhones have this feature built into the camera app under iOS Encrypted QR codes, which are not very common, have a few applications.
For example, there is an Android app,  that manages encryption and decryption of QR codes using the Data Encryption Standard algorithm.
The Japanese immigration system usage of encrypted QR codes on landing permission stamps in passports, is another example.
QR Codes have been used by various retail outlets that have loyalty programs. Usually, these programs are in the form of an app that users can download onto their phone and comes with a feature to scan QR codes, which are found printed on the receipt received when making a purchase, allowing users to collect award points simply by scanning the code.
Unlike the older, one-dimensional barcodes that were designed to be mechanically scanned by a narrow beam of light, a QR code is detected by a 2-dimensional digital image sensor and then digitally analyzed by a programmed processor.
The processor locates the three distinctive squares at the corners of the QR code image, using a smaller square or multiple squares near the fourth corner to normalize the image for size, orientation, and angle of viewing.
The small dots throughout the QR code are then converted to binary numbers and validated with an error-correcting algorithm. The amount of data that can be stored in the QR code symbol depends on the datatype mode , or input character set , version 1, The maximum storage capacities occur for version 40 and error correction level L low , denoted by L: Codewords are 8 bits long and use the Reed—Solomon error correction algorithm with four error correction levels.
The higher the error correction level, the less storage capacity. The following table lists the approximate error correction capability at each of the four levels:.
In larger QR symbols, the message is broken up into several Reed—Solomon code blocks. The block size is chosen so that at most 15 errors can be corrected in each block; this limits the complexity of the decoding algorithm.
The code blocks are then interleaved together, making it less likely that localized damage to a QR symbol will overwhelm the capacity of any single block.
Due to error correction, it is possible to create artistic QR codes that still scan correctly, but contain intentional errors to make them more readable or attractive to the human eye, as well as to incorporate colors, logos, and other features into the QR code block.
It is also possible to design artistic QR codes without reducing the error correction capacity by manipulating the underlying mathematical constructs.
The format information records two things: Masking is used to break up patterns in the data area that might confuse a scanner, such as large blank areas or misleading features that look like the locator marks.
The mask patterns are defined on a grid that is repeated as necessary to cover the whole symbol. Modules corresponding to the dark areas of the mask are inverted.
The format information is protected from errors with a BCH code , and two complete copies are included in each QR symbol.
The message dataset is placed from right to left in a zigzag pattern, as shown below. In larger symbols, this is complicated by the presence of the alignment patterns and the use of multiple interleaved error-correction blocks.
The general structure of a QR encoding is as a sequence of 4 bit indicators with payload length dependent on the indicator mode e. Encoding modes can be mixed as needed within a QR symbol.
After every indicator that selects an encoding mode is a length field that tells how many characters are encoded in that mode.

QR generators were originally used in industrial applications. Therefore, they had to be easily printable in form and size as well as staying legible when partially destroyed or dirty.
Like other codes, the QR code symbol can be captured with imaging devices like a camera and then digitally processed. A software prepares the captured image data until it can be algorithmically processed according to the QR code standard so the QR code content can be read.
This process is assisted by the use of the Reed-Solomon error correction—which is also used for audio CDs to ensure that the data can still be read correctly even with small scratches on the surface.
Modern mobile phones are powerful enough to run QR code reading software and also usually provide a camera. This combination brought up a variety of possibilities to use the QR code to easily transfer data without typing to the peoples new communication center, the smartphone.
Therefore, a widespread use of QR codes became possible with the recent smartphone boom and the increasing spread of mobile internet.
A QR code generator is a software which stores data into a QR code for example a text or a website address.
Now you may print your free QR code or embed it on your website to make it available to others. See What is a QR code generator?
In German, QR-Code mind the hyphen! You can export your created QR code into many formats. However, the patent owners decided not to exercise the rights resulting therefrom.
Also a usage registration is not necessary. Nevertheless a word of warning: Please be aware that a QR code image itself may be copyright protected when created by a third party and therefore may incur usage charges or other fees, depending on the license terms of the used QR code generator.
The QR codes created on goQR. So make sure to always create your QR codes with our generator. Even if all input data and the chosen error correction level ECC are identical, there are various graphical representations of a legible and valid QR code with the same content.
The reason is that there are eight possible data masks which influence the pattern. These masks exist to prevent some module patterns which are hard to decode.
Not every data mask is really suitable for every content. However, many QR code generators do not take the testing and determination of the best mask seriously, although this may result in less legible but still valid QR codes.
Many users are asking if we can embed an image or a slogan into a QR code. And yes, it is possible to to customize a QR code with a logo, lettering, picture or some company color schema.
QR code with logo. Use our service to make your QR codes more efficient. An image in the QR code attracts additional attention and directly shows what the code is about.
You can create colored QR codes with goQR. Normal, static QR codes are fixed. The data is stored directly in the QR code graphic hence QR codes are also getting larger and form a more complex pattern if there is more data to store.
Therefore, the stored data cannot be changed. Any typo in an already printed QR code cannot be changed, as with any other printed material.
Their key feature is that the stored QR code destination address URL can be changed at any time and as often as you want — even if your e.
Adjust your advertising campaigns at any time or correct errors for example, if the wrong web address was used by mistake.
See Change QR code content e. This term allows to account for the technical difference between display pixels and the black and white squares of a QR code.
Barcodes are—simply put—machine-readable fonts. There are different barcode standards. In general, barcodes are used as optical machine-readable labels on objects, containing information about the object on which they are glued.
The most popular barcode type is used on the product packaging and can be viewed at every grocery store where they make the Universal Product Code machine readable.
A barcode scanner or a mobile phone with camera and an appropriate reader app which supports the QR code standard is required to scan a QR code.
QR code reader apps are made available by different manufacturers and for different mobile devices, mostly for free. There are many free QR code reader for Smartphones.
However, they differ significantly in terms of usability, scanning speed and standards compliance in particular regarding the processing of vCards.
Therefore we provide an overview about recommendable QR code software. To summarize, there are plenty of free QR code readers on the market.
There is no complex rules to make your QR codes easily scanable for rather simple capturing devices such as mobile phone cameras.Deutschland — Norwegen Der schnellste Weg zum Wettgewinn!
