Patent ID: 7441699

Claim:
An output terminal which transmits/receives electronic data to/from another output terminal, the output terminal and the other output terminal provided apart from each other in at least one building, the output terminal comprising: a communication unit which transmits/receives a specific code for specifying the electronic data and a destination of the electronic data; a storage device; an antenna which reads an identification code from an IC chip storing therein identification codes corresponding to specific codes on one-by-one basis; an output unit which outputs the electronic data; and a CPU which performs the steps of: (a1) receiving the electronic data and the specific code, (a2) storing the electronic data and the specific code in the storage device, (a3) causing the antenna to read the identification code, only when the IC chip storing the identification code is within a predetermined range, (a4) determining whether the read identification code corresponds to the specific code stored in the storage device, and (a5) causing the output unit to output the electronic data when the identification code corresponds to the specific code, and when the IC chip storing therein the identification code corresponding to the specific code is within the predetermined range.
