Photographing system and photographic information transmission system

A photographic information transmission system in which a signal relating to photographing is transmitted from a first hand-held terminal, wherein:

• at least one of the first hand-held terminal and the second hand-held terminal is provided with a unique identification code for identification of the first hand-held terminal or the second hand-held terminal;
• the second hand-held terminal comprises a collating section for collating a unique identification code that is transmitted from the first hand-held terminal by making a physical connection between the first and second hand-held terminals via lead wire or contact points, with a unique identification code originally provided in the second hand-held terminal;
• the first hand-held terminal has the unique identification code of the second hand-held terminal transmitted in advance through the physical connection between the first hand-held terminal and the second hand-held terminal via a lead wire or contact points, and in controlling the second hand-held terminal the first hand-held terminal sends the unique identification code of the second hand-held terminal to the second hand-held terminal through the physical connection via the lead wire or the contact points;
• and
• the collating section collates the unique identification code of the second hand-held terminal that is transmitted from the first hand-held terminal through the physical connection via the lead wire or the contact points, with the unique identification code of the second hand-held terminal provided in the second hand-held terminal.
