Abstract: A computer system for tracking the interest of visitors and vendors in a trade fair. The system has a plurality of sets of tokens, where each set of tokens has a unique ID which is associated with a visitor. A data entry device compatible with the sets of tokens is connected to a computer. A database is maintained by the computer and stores the associations between the unique IDs and the visitors.

Each token placed in communication with the data entry is representative of the visitor associated with the token having an interest in the vendor which is being processed.
