Can you imagine a modern person without an iphone, windows phone or a smartphone running on android?.. Many of these smartphones come with already installed decoding-apps, and when they don't one can always download one of hundreds of free apps, which means that literally every second person can decode a QR-tag.
QR-Code tagging is becoming a popular trend in media and everyday life. They are not just a new generation of bar codes. QR is more than that. QRs are nice and sexy, and most of all QR codes look so interesting that you want actually to DECODE them!
All this makes a personal QR-code tag an absolutely cool widget for you or a great gift for your friends. It doesn't just look good, it FUNCTIONS! Encode a message, a link to your website or online portfolio, your additional emergency info, or any any other text in this little tag, or use it as a one-of-a-kind business card!
Moreover: you decide what color you want it. But, please, note that the dark "dots" should be dark enough in comparison to the light-colored "surface".
Please note, that with extensive use the colors will fade out over time and scratches will appear.
