Abstract

The portable automated teller machine disclosed by the present invention is a low-cost, pocket-size data terminal which can securely exchange information with a host bank computer. It is battery powered, operates without the need for direct connection to a telephone line and couples to the host bank computer via the telephone handset of any public or private telephone station. It allows its user to securely access bank and bank accounts and to securely effect either inter-account transfers or bill payments. Security is assured by assigning a PIN to each individual user and prestoring it therein, by assigning a machine identity number to each machine and storing it therein, and by providing encrypted data communication. It has prestored therein the individuals account numbers and the phone numbers and other parametrs needed for communication to the corresponding host computer bank. It features foldable telephone receiving ears pivotally mounted to a housing member, and an overlayed touch screen mounted flush with the housing member. A calculator function is also provided.

a housing;

I/O means mounted to said housing for enabling data and command entry and for displaying data and possible command selections;

memory means mounted to said housing for storing a predetermined personal identification number;

memory means mounted to said housing for storing a predetermined machine identity number at a different memory location than that of the predetermined personal identification number; and

bi-modal means mounted to said housing and cooperative with said I/O means and responsive only to the predetermined personal identification number (PIN) entered via said I/O means for both allowing a block of data representative of a transaction to be transacted with the remote host computer to be set-up in the memory means via the I/O means in an off-line mode and for transmitting that block of data and including the predetermined machine identity number to the remote host computer via the handset of any telephone station in an on-line mode after the block of data has been set-up substantially completely in the off-line mode, and responsive only to the predetermined machine identity number (MIN) having been matched at the remote host computer for receiving data back from the remote host computer representative of the status of the transaction in the on-line mode and for displaying the data received back from the remote host computer representative of the status of the transaction via the I/O means again in an off-line mode.
