QR Codes are a popular type of two-dimensional barcodes that are used to display text, business cards, web URLs, email addresses and other kinds of text to a mobile phone user.
The tool generates QR codes using the Google Charts API. All QR images have a unique URL that you can directly hotlink in your email signatures and web pages.
