Barcode is the dominant track and trace technology on the planet. RFID is an emerging successor in some applications, a valuable complement in most. Barcode is used globally throughout most industries and is the de facto standard for most companies, regardless of tier or location. RFID is an emerging solution, capable of extending the value proposition of barcode by providing additional functionality and removing the limitations of line-of-sight scanning. Although these two technologies could be perceived as direct competitors for the same applications, end users continue to require both solutions—and this is not a short term condition.
