<p>The present invention is concerned with a transaction terminal apparatus for executing transaction processing with a customer in which certain elements are required to be tamperproof. With this invention those structural elements of the transaction terminal apparatus that need to be tamperproof are constituted as a module 2 that is removable from the main body 1 of the transaction terminal apparatus. Since the module 2 is constituted so as to be tamperproof, the main body 1 of the transaction terminal apparatus does not need to be made tamperproof. The elements required to be tamperproof are contained in the module so that they can be removed from the main body. The application programs relating to various types of transactions stored in the main body can be easily added to, modified, revised, and updated, without having to open a tamperproof unit, making the unit versatile and easy to upgrade. <IMAGE></p> |
