How do you generate a QR code for a not so popular coin? I'm running a the datacoin-qt client and was wondering how do you generate a QR code? This is relatively a new coin and I can generate an address, but I'm not sure where I can goto to generate a QR code for this.
Do you want to just generate the QR code for one time use, or include the code generation into a program? If the latter you can use this for javascript: http://larsjung.de/qrcode/
