Portable QR-Code Generator

The 'Portable QR-Code Generator' is a free Java program which generates QR Codes from

WLAN credentials: SSID, network key and and network type (WEP, WPA/WPA2, not encrypted)
The so-called 'WiFi-Code' can optionally be printed as a folding card: after folding the printout the QR Code is on the front side, the credentials in plain text on the back side - this way you have all the information available you need to connect a device to the network, regardless of whether the device can read and interpret the code or not.
The orientation of both the code and the text can be changed, also the font and the font size.
Inlined images can optionally be removed to reduce the size of the generated QR Code
VCards up to version 3 (inclusive) are supported
You can import the cards via drag&drop or by selecting them in a file chooser dialog
Supports a broad range of character encodings (ISO-8859-1, UTF-8, UTF-16, ...) - the actual number depends on the Java Virtual Machine you are using.
VCard generator
Generates VCards of the upcoming v4 (RFC 6350). New: Saving and loading of VCards.
e-mail addresses
free text
geographic coordinates

The QR Code can be printed, saved as BMP, GIF or PNG, or copied to clipboard to use in other applications.

Running the generator requires a Java Runtime Environment (JRE) 6 or newer. In most cases the program can then be started simply by a double-click on its JAR-archive. An installation is not necessary, the archive can be in any folder.
