IFCO's asset tracking produces results (sidebar)

The color wheel decoded

It’s a colorfully different automatic identification system, but how does Visidot’s ColorCode™ work? It starts with a high-resolution digital image taken by the Visidot reader. The image is processed using proprietary detect-and-decode software, explains Roger Hecker, Visidot’s product marketing manager. The software efficiently checks the image pixel-by-pixel to find the ColorCode, after which the program’s algorithms decode the information and translate it into a number format. Those numbers match up with a Global Returnable Asset Identifier, or GRAI number, which is the same number that appears in IFCO’s bar code.

Because the GRAI data also includes company and type of crate, which IFCO already knows, IFCO uses the ColorCode to carry the returnable plastic container’s serial number only.
