Abstract

A settlement terminal includes a reading unit configured to read card data, a settlement processing unit including a processor programmed to carry out a settlement process using the card data and a tampering detection process, a storage device in which a first set of programs is stored after encryption by a first key and a second set of programs is stored after encryption by a second key, each set of programs including a first program for operating the reading unit, and a second program for carrying out the settlement process. Upon detection of tampering, the processor of the settlement processing unit notifies an external terminal of the tampering and upon receiving an update instruction from the external terminal, updates a current set of programs used for operating the reading unit and carrying out the settlement process from the first set to the second set.
