They may seem simple and in a sense they are. “QR” is the abbreviation of Quick Response Code, which is a type of barcode (a two-dimensional matrix). These little tricksters were invented in 1994 by Denso Wave. The most common type refers you to a URL (or website/webpage) but you can also sent an SMS, email address, phone number, geolocation, WiFi and more.
When you scan or read one with your mobile phone, it will open the URL encoded in the image. If we take our example of a QR code on a tombstone, it really just opens a webpage with information about the deceased. It's only a question of what you want to link up to with your QR code. If you sell products in groceries or hardware stores, you might want to add a one to your product to share your company website for after sales services. Maybe you are selling properties? You could place a QR code on the sign outside so that people instantly obtain more detailed information. Does your city feature sculpture in its parks? Use a QR code to provide information about both the sculpture and its artist.
QR codes can be placed anywhere you what to share information, but they must be discreet and not too invasive.
