PROBLEM TO BE SOLVED: To shorten transaction time and to reduce transactor's load. SOLUTION: A certification part 2 executes personal identification from picture data obtained by an image pickup part 1. A continuous transaction control part 4 records the input contents of respective transactions in an input contents recording part 3. When an optional transaction is started, the control part 4 judges whether a current transactor personally identified by the certification part 2 is the same person as a preceding transactor or not. In the case of the same person, the control part 4 extracts contents common to the current transaction from the input contents recorded in the recording part 3 and uses the extracted contents for the current transaction. |
