Based on a similar model to GS1’s central registry of Universal Product Codes (UPCs) Neustar’s mobile barcode clearinghouse service announced in February 2010 (press release), appears to have faltered or maybe even been abandoned.
An original element of Neustar’s proposed service was the use of an indirect 2d barcode encoded with a proprietary text string allocated by Neustar. Few examples of these have been seen in the wild but they have appeared on Neustar’s website and one was used in a joint Visa, NeoMedia and Neustar promotional contest at Mobile World Congress 2010. These codes required non-standard scanners that could interpret the text string and forward it to Neustar’s servers for redirection. As far as I know there were only four scanners out of a hundred plus that could actually do this.
What has changed now is the QR Code on Neustar’s website that decoded as the text string mc*neu*23 has been replaced. The new QR Code decodes as http://bc4.biz/mc*neu*34 and hence can be read by any 2d code scanner. This brings Neustar into direct competition with other 2d barcode campaign management systems and probably heralds the end of their clearinghouse project.
