What is a QR Code?
QR Codes are two dimensional barcodes that are designed to have their contents decoded at high speed.
Here's an example:
How Do They Work?
Take a mobile phone such as the iPhone; nearly every mobile phone has a digital camera in today’s world. The camera, along with decoding software can be used to capture a picture of the QR-Code and then transform the data held with the QR-Code to a meaningful action for the mobile phone:
- Connect to a web address
- Download an MP3
- Dial a telephone number
- Prompt your email client with a sender address
- Share calendar events
- Provide driving directions or a map using your phone's navigation software
This can all be done within a matter of milliseconds making the transformation from a user’s mobile phones browser to the mobile web instantaneous.
Barcodes vs. QR-Codes
Picture of Traditional Barcode
QR-Codes have become more popular than the typical barcode as the typical barcode can only hold a maximum of 20 digits, whereas the QR-Code can hold up to 7,089 characters. This makes the use and diversity of QR-Codes much more appealing than their older counter part, the barcode.
Partially part of the reason QR-Codes can hold more data, is because if you compare a typical barcode to a QR-Code, you can see one major difference; barcodes only span horizontal whereas QR-Codes can span horizontally and vertically.
Statistic – QR-Codes are capable of encoding the same amount of data in approximately one-tenth the space of a traditional bar code. Such minute QR-Codes are called Micro QR-Codes.
