The system comprises at least one database for retaining updatable item-specific information, together with a gateway server for connecting each database to the Internet or a similar communications network and interfacing the database with a telecommunications network, such as a mobile (cellular) telephone network. The system includes means for accepting remote interrogations of said at least one database via the telecommunications network from a mobile telephone handset or Personal Digital Assistant (PDA). The invention also provides a method of accessing and transferring item-specific information, the method including generating a Short Message Service (SMS) text message including an item identifier on a mobile phone or PDA, transmitting the item identifier to an indicated SMS target number to make an information request validating the item specified and generating item-specific information which is transmitted back to the mobile phone or PDA, thereby providing rapid access to additional item-specific information. Additionally, the invention provides a computer system incorporating a database and software enabling the implementation of the system and method of the invention, including means for accepting and validating remote information requests and means for generating item-specific information for transmittal to the mobile phone or PDA identified in an information request.
