Many worldwide advertising agencies and companies currently use QR codes, two-dimensional (2D) bar codes, to promote their organizations' or clients' brands and products.

Each scan of a QR code can not only stream location data, but product-specific information as well.

QR codes are highly popular since they are able to support and transfer more information than radio frequency identification (RFID), near field communications (NFC), or traditional bar codes. The devices that read QR codes - standard cameras on smartphones - can send information through cellular service to any connected Web-based application.

However, many electronics manufacturers are presently pondering the following question - should they consider using QR codes to track goods through their own supply chains?
