INFORMATION TERMINAL AND METHOD OF CUTTING OUT POWER SUPPLY TO BACKUP BATTERY MOUNTED ON THE INFORMATION TERMINAL, AND SETTLEMENT TERMINAL AND METHOD OF CUTTING OUT POWER SUPPLY TO BACKUP BATTERY MOUNTED ON THE SETTLEMENT TERMINAL

摘要

PROBLEM TO BE SOLVED: To prevent the personal information of users from leaking by protecting information terminals such as settlement terminals against skimming. SOLUTION: A backup battery 10 supplies power, through a bypass power supply passage 12, to a storage part 61 via units 2, 3, and 6 from a reading unit 2 to a main control unit 6 forming a personal information transmission passage 11 for transmitting personal information. When any of the units 2, 3, and 6 from the reading unit 2 to the main control unit 6 is extracted when a skimming memory is installed in the personal information transmission passage 11 for transmitting personal information to skim personal information, a power supply to a storage part 61 is cut out. Thus, security information stored in the storage part 61, for example, start data for starting an information terminal 1 is ruptured.
