TRANSACTION TERMINAL UNIT AND TRANSACTION TERMINAL CONTROL METHOD

摘要

A transaction terminal device includes a non-tamperable secured module (120) that is incorporated in a main unit and a tamperable unsecured module (110) that is embedded in the main unit. Further the secured module (120) includes a LED controller (125) that notifies secure information to a user via a LED (124), a keyboard (122) that obtains PIN information, and a code processor (121) that encrypts the obtained PIN information. The unsecured module (110) includes a CPU (111) that executes the processing of a transaction using the PIN information received after being encrypted by the code processor (121). <IMAGE>
