A Brief History of QR Codes

A QR Code is a specific matrix barcode (or two-dimensional code), readable by dedicated QR barcode readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data. Common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes.

QR is the abbreviation for Quick Response.

Although initially used for tracking parts in vehicle manufacturing, QR codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users. QR codes can be used to display text to the user, to add a vCard contact to the user’s device, to open a URL or to compose an email or text message. Users can also generate and print their own QR codes for others to scan and use by visiting one of several free QR code generating sites.

QR Codes in Marketing

Recently, QR codes have become more prevalent in marketing circles and have been integrated into both traditional and interactive campaigns. Media where QR codes have been deployed include:

  • billboard ads

  • guerilla marketing campagns

  • in-store displays

  • event ticketing and tracking

  • trade-show management

  • business cards

  • print ads

  • contests

  • direct mail campaigns

  • websites

  • email marketing

  • and couponing just to name a few.

QR codes are of particular interest to marketers, giving them the “ability to measure response rates with a high degree of precision” allowing for easier ROI (return on investment)  calculation, thus helping justify spending on marketing budgets. QR codes have also been used at trade shows and in conferences.
