Upon returning to my car after a workout at the gym, I found a hand-written note along with a business card tucked under my car’s windshield wiper. Long story short, I was using someone else’s car that day. The tags are registered in a different state.
The note started off by saying, “Good Morning! I noticed your license plate and thought you might need a place to rent/buy in Austin…” The business card accompanying the note was from a Realtor® in Austin. What caught my attention was the QR code printed on the real estate agent’s business card.
More and more professionals are starting to use QR codes and other marketing technologies, like SMS texting and unique key codes, with direct mail and print to assist in lead generation, drive deeper customer engagement, and track campaign performance. Very smart; however, there are some things to keep in mind in order to maximize the efficacy of QR codes.
Tell people what will happen once they scan the code. QR codes without instructions or clues as to what will be delivered on the other end could either entice or discourage people to scan them. Until they become widely adopted by marketers and advertisers, and more frequently used by consumers, it may be a good idea to include language that describes what will happen once a code is scanned.
For example:
- Call for info
- See more info
- Visit my site
- Get coupon
- Sign up now
Size QR codes appropriately, and test. I think it’s pretty safe to say that a large percentage of phones in the marketplace come equipped with cameras and have the ability to run mobile applications, like a QR code reader. The unknown is the quality of the many different types of QR code reader apps available and image resolutions of camera lenses used in mobile phones today. Why does this matter? The more complex the QR code (more data embedded in QR codes make the design more complex) the more tiny boxes in the design a reader app needs to identify in order perform an action; cameras on phones help the reader apps do this. The fewer megapixels a camera has, the harder it is for it to identify all the intricacies of a complex QR code. For example, my iPhone 4 with a 5-megapixel camera can read some QR codes that my friend’s iPhone 3G with a 3-megapixel camera can’t (same goes for older Blackberries and other phones with lower resolution cameras).
How does one overcome all these possible variations? Just know that the more complex the QR code you produce, the larger its dimensions should be when displayed in print or published on a digital platform. A safe size of a QR codes in print is about 1 inch by 1 inch. Adjust the size based on where the QR code will be displayed and/or based on its complexity.
Tip: If you are using a QR code to direct people to a website, use a URL shortener to convert long web addresses to shorter ones. This will help reduce the complexity of the QR code.
Whatever size you end up going with, test, test, and test. Ask a friend or co-worker to use their phone to scan the code. Find a good range of phones—of different types, brands, and with different camera resolutions—to test with before finalizing the size of the QR code you end up using. Download a few QR reader apps and test with those as well.
