Claim:
A communication system, comprising: a plurality of service servers each provided with an identification code/URL conversion table; a plurality of information transmission servers each provided with an information storage; and a terminal unit that is connected through a radio or wire communication network to said information transmission servers, said terminal unit having a function for communicating with a Web server; wherein said terminal unit makes a unique link to one of said service servers based on a pattern recognition performed on an exclusive graphic pattern that is a part of a service identification tag, reads an identification code from the service identification tag that is composed of said exclusive graphic pattern that is recognizable by a human and said identification code that can be read by a reading unit, sends the identification code to said one of said service servers and receives a URL information of one of said information transmission servers corresponding to the identification code from said one of said service servers, wherein said terminal unit includes: a data storing part; and an identification tag reading means for conducting a pattern recognition of said exclusive graphic pattern, and an automatic calling means for automatically making a call to said one of said service servers when said exclusive graphic pattern read by said identification tag reading means coincides with a graphic pattern that is stored in advance in said data storing part, wherein, only after said terminal unit has initially contacted said one of said service servers when said exclusive graphic pattern read by said identification tag reading means coincides with said graphic pattern that is stored in advance in said data storing part, does said terminal unit convert said identification code to text code and output the text code to said one of said service servers, in order to request URL information of said one of said information transmission servers.
