Smartphones and QR Codes to Drive Bitcoin Transactions

Welcome to the digital age. With a quick snap of a smartphone camera, QR codes can be scanned from signs, product labels, pieces of paper, computers, TV screens, even clothing. QR codes seem to be popping up more and more, but for a lot of people, they are still somewhat foreign objects. 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.
