QR codes are two-dimensional barcodes, which means that they encode data in two directions, decoding information at a much higher speed. First created by the Japanese corporation, Denso-Wave, in 1994, QR codes were designed to allow their contents to be decoded at a high speed and even if partially damaged, the data can still be extracted.

In comparison to some of the barcodes you may be used to, individual QR Codes can hold as much as 50 times more information and up to 16 QR codes can be linked together, creating series of codes for even greater capacity or simply using a series smaller codes in place a larger one.

Just think of all the credit and debit cards a person has to carry around with them. Why not just use your phone? Just walk up to a vending machine and pay with your phone or purchase goods in a convenience store the same way. Not possible you say. Try telling that to the Japanese.

QR codes, utilized in paperless transactions, have allowed major retail chains in Japan to enhance distribution efficiency through cooperative technology with their shippers in key areas such as apparel and cosmetics. As well, automated reporting has provided additional efficiencies for suppliers and wholesalers, who can better manage their logistics through monitoring feedback.

At exhibitions, seminars, and trade shows registration and entry can be streamlined by using a QR coded ID badge or displaying a QR code on your phone. Better still, what about planes, trains or any other queue?

In large companies, asset management is commonplace and QR codes facilitate inventory control and loss prevention. Now, with the phone as the reader, anyone can benefit by placing QR codes (either visible or hidden) on their own property.
