There is disclosed a method and a system for accessing information and/ or data available on a wide area computer network (100), such as the Internet. A first modulated acoustic signal (A) is transmitted to a group of potential users each provided with a portable communication unit (1, 1 *), this first modulated acoustic signal including at least one identifier (ID_1, ID_2, ID_3, ...) associated with a link to a determined site of the wide area computer network. These identifiers are stored in the portable communication unit then subsequently downloaded to a computer terminal (50, 51, 52) connected to the wide area computer network. After the download ed identifier or identifiers have been compared with a determined list of identifiers (ID_A, ID_B, ID_C, ...), a list of links (Link_A, Link_B, Link_C, ...) to sites corresponding to the downloaded identifier or identifiers is generated by the computer terminal.
