A QR code (a.k.a “Quick Response” code) is a bar code readable by mobile phones. They can store different types of alphanumeric data such as website URL’s, bitcoin addresses, email addresses, plain text, and phone numbers. While not a new invention, QR codes are becoming increasingly popular with the rise of bitcoin. Since bitcoin is an intangible digital currency, it is easy to see why QR codes are such viable tools for these transactions.
How Smartphones Read QR Codes
A smartphone just needs a camera and QR code reader app installed, and like magic, the mobile device is upgraded to a new world of digital possibilities. What can you do with QR codes? The ways in which this digital technology can be used are almost unlimited. QR codes are not just for sending and receiving bitcoin, they come in handy for quickly navigating web links, promoting fundraising campaigns, or for business applications.

- paying for advertised items
- parking meters

One example that points to the power of smartphones for driving bitcoin transactions is the Alabama college student who rounded up $24 thousand in anonymous bitcoin donations. In Dec 2013, the student held up this sign asking for bitcoin donations at a sports game aired on ESPN:
The donations flooded in. The student decided to donate 11 BTC, or approximately $11,700 to Sean’s Outpost, a non-profit organization. It is also an example of how smartphones make the process of raising bitcoin donations easier and faster.
