What Are QR Codes?

QR Codes (Quick Response Codes) are two-dimensional barcodes that can easily be read by devices with a scanner or camera and where created for simple but quick data entry to perform a quick task. You can read the Wikipedia Page on QR Codes here.

QR Codes are most commonly used to link the physical world with the digital world in a quick and easy to use way. Such examples are scanning a QR code you find in a magazine to visit a product page on a website, or scanning a QR code on a food menu to view pictures of the food.

You can store virtually any type of textual data in a QR code which include website addresses, VCard information, SMS templates, etc, or just plain text.

What are Dynamic QR Codes?

Dynamic QR Codes are QR codes that don't change in their visual appearance once created, but can change in what they do in the future. For example, you may need a dynamic QR Code if you want to change your website address in the future but don't want to update your brochure that show your QR Codes. Replacing printed QR Codes when web address change etc can be very expensive.

Simply open the app, start a scan, point the camera towards the QR Code and the app should handle the rest.

QR Code Example

Random QR Code

The above QR Code is just a random QR Code you can use in examples like presentations, stock photography or IOS apps.

Customizing QR Codes

QR Codes can be customized to a certain extent and you can change background, foreground, eye colors (the squares at the top & bottom left, and top right) and even add logos to the center and customize what appears around the QR Code such as borders, graphics etc. You can also adjust the padding and pixel size of the dots too.

QR Code Tracking

It's possible to track the scans and uses of QR Codes but this requires most codes to be dynamic QR Codes. By using dynamic QR Codes we can serve up the correct content with each scan while tracking things like visitor count, device and dates etc.

QR Code Formats

QR Codes can be created in a few formats but they work best in something called a scalable graphics format, which means they don't loose quality once you scale them in size. Such scalable formats include SVG and EPS.

You can also create QR Codes in lossy graphic formats which means the quality will probably degrade if you try to scale them in size. Such lossy file formats for QR Codes include PNG and JPG.

QR Codes For Print

If you intend to use your QR Codes generated here for print then we recommend you use the vector formats available (SVG & EPS formats) as these will scale correctly when used by publishers.
