QR Codes or “Quick Response Codes” are ubiquitous. They can be seen everywhere and in myriads of aesthetic variations. However, they exist for one purpose and one purpose alone: data storage. Among others, QR codes contain (1) website URLs that triggers browsers to go to that website; (2) phone numbers and business cards that automatically get stored in mobile phones; and (3) inventory codes that let business owners track and manage assets they own.
A QR Code is easy to read. It does not require any specialized equipment to capture its encoded content. It only needs a computer with a camera attached to it. In this regard, any smart phone, laptop, or tablet with a QR Code reader App can be used. Moreover, QR Codes contain more data than the standard UPC barcodes. Further, and most importantly, QR Codes can be read faster than traditional encoded badges.
