I have tried many different QR code platforms/apps and none of them come anywhere near how good ElkQR is. The digital business card QR was just the solution I needed. No other system's digital business card works like this one. I like how the QR code doesn't change when you make edits to your business card. That by itself makes this far superior to any other. But its flexibility and ease of use puts it over the top. I cannot say enough about ElkQR except that, if you are looking for a QR code platform that works and is constantly being improved, get this one. It is worth every penny!
