Abstract
A method and system for providing access to information on an article to which a tag is coupled. A local server reads the tag containing a virtual ID that includes an encryption of a bit string. The bit string includes an article ID containing a manufacturer ID. The local server is coupled to an ONS server, an ONS proxy server, and a PML server via a network. The local server sends to the ONS proxy server an ONS service request that includes the virtual ID and requests a network address of the PML server. The local server receives, from the ONS server, the network address of the PML server. The local server sends to the PML server, at the network address of the PML server, a PML information request that includes the virtual ID and requests article information. The local server receives, from the PML server, the article information.
