I'm looking for a library to generate QR codes in .NET I've stumbled across a few paid ones, but very few free ones that look any good. Anyone have experience with a good free open-source library?
Thanks
QRCode Monkey is one of the most popular free online qr code generators with millions of already created QR codes. The high resolution of the QR codes and the powerful design options make it one of the best free QR code generators on the web that can be used for commercial and print purposes.
Do QR codes expire? Free QR codes or static QR codes are generated using a QR Code generator online and they do not expire.
Near field communication (NFC) tags are one of the new tools that could potentially replace QR codes. Unlike QR codes, NFC tags do not require an extra application. The NFC chip technology already comes built into the majority of modern smartphones, which is a huge advantage.
Take a look at this one http://qrcodenet.codeplex.com/
