Automated teller machine (atm) including an application programming interface (api)-equipped, embedded mobile computer

A method for enabling communication between an automated teller machine (ATM) comprising a mobile computer a back-end server, a socket, and not comprising a screen, the method comprising:

• removably deploying the mobile computer in the socket;
• receiving information relating at an ATM central processing unit (ATM CPU);
• providing, using the mobile computer processing using a mobile computer CPU (MC CPU);
• receiving, at a mobile computer keypad, user identification information in the form of a PIN entered by a user;
• receiving at the back-end server authentication information from the ATM, said authentication information for authenticating the user for a session at the ATM;
• using a touch screen at the mobile computer, said touch screen configured to display, in the event that the MC CPU determines that a data structure associated with the information corresponding to the PIN entered by a user corresponds to a valid PIN, an initial ATM display that comprises multiple transaction options;
• interfacing between the ATM CPU and MC CPU.
• using the back-end server is configured to format and transmit to the ATM an application programming interface (API) call, said API call for requesting a location of the user, ATM device information, and identification information of the user;
• and
• using the mobile computer, exclusively when the mobile computer is installed in the ATM, to respond to the API call by providing the location of the user, the ATM device information, and the identification information of the user to the back-end server.
