There was a time when you would have to write a letter to express your thoughts. I remember that there was a place where you would usually write the address. So the other person would know your location. And finally if we fast forward to recent time, you have a website or app URL which is sometimes not short. Sharing it is sometimes painful. But apart from shortening the link and do other funny stuff, you can create a QR code and share the image. QR code is easy to use since you just need to keep the Phone in front of the QR code and it will instantly read the link. I have developed a QR code which is easy to use and very small in size.
Feel free to download the link.
