The quick response, or QR, Code is a two-dimensional Barcode which conveys hidden information instantly in the code with the scan of a mobile device.
Able to store up to 7089 digits or 4296 characters, including punctuation marks and special characters, the Code can equally encode words and phrases such as internet addresses. One thing to always keep in mind, especially when it comes to designing the Static QR Codes is that the more data is added, the more the size increases and its structure becomes more complex.
Even when damaged, the QR Code’s structure data keys include duplications. It is thanks to these redundancies that allow up to 30% of the Code structure to take damage without affecting its readability on scanners.
Using this code is quite simple. Just enter your text, your URL, any product information or contact information. The QR code will be generated as you click on the generate button. You can Easily Download the image in PNG format or you can also take a printout. Also, you can place and use the QR graphic on leaflets, posters, business cards or other products without any costs /for free (including commercial use).
It is the perfect solution to generate data. QR codes are the way to create a link between the real world products and the Internet. QR codes are Mobile, and cab used anywhere, anytime. Because QR codes make it so easy to transfer a web link to a mobile phone, they provide a significantly lower barrier to visit a site with a smartphone. But you can also work with other texts and data, such as advertising messages, telephone numbers and even entire business cards in this format. Just encode them with our QR code generator to easily transfer the data to mobile devices.
QR codes store binary data. Therefore, possibly all kinds of information can be stored in a QR code. However, the storage capacity of a QR code is limited to a maximum of 3 kB (using an 8 bit encoding) which naturally limits the possibility to directly store images and sounds.
From a technical point of view , QR codes do not expire or get invali. The information a QR code offers after scanning is stored in the graphic itself hence QR codes form a more complex pattern if there is more data to store. The stored data cannot be changed and therefore a QR code does not “expire” after a certain time.
What is a QR code?
A QR code is a two-dimensional code. QR code symbols can be captured with image capturing devices like a camera, mobile phones 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.
What kind of information can be stored in a QR code?
You can store short texts, SMS, all kinds of URLs and websites (Youtube, Facebook, Homepages), contact details, dates and calendar entries, WiFi access credentials, geo and navigation data and much more.
How long are QR codes valid? Do QR codes expire?
From a technical perspective QR codes do not expire or get invalid. The information a QR code offers after scanning is stored in the graphic itself. The stored data cannot be changed and therefore a QR code does not “expire” after a certain time.
