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 , 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 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 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 , 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 stored in the receiver database and, based on the comparison, provides access to the issuer profile and/or the subdirectory ; <EOS>
