QR Mirror
This site can be used to link a QR code to a short message. The full content of the message is encoded in the URL pointed to by the QR code, so unlike with a URL shortener nothing is stored server-side.
Usage
Give it a try by changing the text below and hitting Go!. If you scan the resulting QR code it will link back to the same page. This can be used, for example, to quickly transfer text from PC to phone or between phones.
Formatting
You can use markdown for rich text formatting. To prevent formatting, you can wrap the message in triple backticks (```).
