A computer-implemented method for managing and transmitting information in an information management system composed of at least one server provided for storing information, at least one tag provided with a tag code, a portable communication device configured to establish a connection with said tag, said portable communication device having a receiver profile associated thereto, the method comprising: - storing on the server at least one issuer profile, wherein said issuer profile comprises an issuer code; and - linking up the issuer profile with the tag, associating the issuer code with the tag code; - assigning to the tag a link associated with the tag code which gives access to the issuer profile stored in the server; and - the issuer profile comprises at least one subdirectory, said subdirectory being able to be selected for access, wherein, in a connection status between the portable communication device and the tag, said portable communication device is prepared to interpret the link of the tag, open said link to access the issuer profile stored in the server, and further access the subdirectory; the method being characterised by: - storing on the server a receiver database comprising receiver profiles (51, 5m, 51', 5m'), such that, in the connection status between the portable communication device and the tag, said tag transmits to the server the receiver profile associated with the portable communication device, compares said receiver profile with the receiver profiles (51, 5m, 51', 5m') stored in the receiver database and, based on the comparison, provides access to the issuer profile and/or the subdirectory; wherein the issuer profile further comprises at least one confidential subdirectory, such that in the connection status between the portable communication device and the tag, said tag transmits to the server the receiver profile associated with the portable communication device, compares said receiver profile with the receiver profiles (51, 5m, 51', 5m') stored in the receiver database and, based on the comparison, provides access to the issuer profile and/or the subdirectory and/or the confidential subdirectory. - storing on the server at least one issuer profile, wherein said issuer profile comprises an issuer code; and - linking up the issuer profile with the tag, associating the issuer code with the tag code; - assigning to the tag a link associated with the tag code which gives access to the issuer profile stored in the server; and - the issuer profile comprises at least one subdirectory, said subdirectory being able to be selected for access, wherein, in a connection status between the portable communication device and the tag, said portable communication device is prepared to interpret the link of the tag, open said link to access the issuer profile stored in the server, and further access the subdirectory; - storing on the server a receiver database comprising receiver profiles (51, 5m, 51', 5m'), such that, in the connection status between the portable communication device and the tag, said tag transmits to the server the receiver profile associated with the portable communication device, compares said receiver profile with the receiver profiles (51, 5m, 51', 5m') stored in the receiver database and, based on the comparison, provides access to the issuer profile and/or the subdirectory;
