QR Codes are great bridge to grab some mobile attention; QR code generators are simple if you have some basic internet knowledge and there are many videos available to help you through the process
With QR Codes you can generate traffic into select pages on your web site, Facebook page or other social media; they can invoke the users email service to directly sign up for an email newsletter, or down load a short data file right into their device.
This is a great way to get people to get people to make a direct connection at the time when they show the most interest.
Placement; do not put these code in high mobility areas, the simple act of scanning takes enough time that most people the ideal place will be one that is visible from high traffic area to attract interest but you need a standing area out of flow where they can actually take the 3 seconds to scan your code.
Another smart location is on any handout material that you use. Rather than printing massive volumes of material, post the material on your web page, and hand out a cover letter with URL’s and QR codes to allow people to connect with just the information they want, you gain the advantage of tracking when you process things through your website if you hand out a booklet of material you do not know which item attracts people, if they go through your web site you will have some knowledge about what they specifically read. When you hand out a big book of material that is a big expense that may go right into recycling when they are out of sight, on the other hand have full printouts available, you never can tell when one of those 35% who do not use smart phones will want to be your customer.
