The QR Code was invented for the automotive industry. Toyota asked their supplier Denso Wave to develop a barcode for safely and easily identifying components. QR generators were originally used in industry. Because of the outstanding error correction performance (they can be read even if up to 30% of the surface are destroyed) and a lot of applications, the QR Code quickly made its way around the world.
QR Codes can do more
QR Codes can contain more than just a simple link to a website: Use them to link to a video, your Facebook profile or an MP3 file—anything a modern smartphone is capable of doing. Directly take your visitors to the relevant content, without the hassle of typing in complicated URLs. Some examples:
- Play a Youtube video
- Add an entry to the user's calendar
- Start an image gallery
- Ease installing an app from the App Store or Android Market
- Send a predefined short message (premium services)
- Send a Tweet with your content
- Visit Google+/Facebook profile
- Call a phone number
- Show contact data as a vCard/meCard
- Show your branding on textiles (T-shirts, bags) and other articles like mugs
- Show your profile on recommendation services like Qype
- Use QR Codes in blogs (Wordpress etc)
