In this case, Scirocco IRID makes use of a punched metal barcode that is captured by a Scirocco reader when it crosses a coded infrared beam. The maximum passage speed is very high, the barcode can be read regardless of its passage direction or orientation, and the barcode-reader distance is uncritical and allowed up to two metres or more. The new metal barcode reader makes it possible to use Scirocco IRID all over an automotive factory, from the welding shop through the paint shop and further on in the final assembly line. In difference to radio based tags, that not only cost a fortune but that also are vulnerable to soaking in anticorrosion baths, repeated cycling at up to 200 °C and agressive paint rinsing processes, a metal barcode has low cost and an almost infinite life. The first demonstrator system was sold to South Korea.
