We see alot of QR Codes on
signs we print for our clients. Not sure if they are a fad or not, but I think they surely can be useful.
They work as a great "linking" tool, linking products or items in the real world to specific webpages. They are fantastic on packaging or print catalogs because a consumer can use their phone to gather more information or watch a video about the product they are thinking about purchasing.
We'll be adding something like this to our catalog in the future. A great way to link to templates, product videos, idea guides, etc.
Most importantly though, we're in the business of helping our customers get more business. It's important to realize the potential of this and other media tools to help our customers get the attention they need. Don't worry about whether or not you should have one. Do your customers need to be using QR codes?
