Claim 0:
1. A contact-minimized automatic teller machine (“ATM”) comprising:
a housing;
a microprocessor disposed in the housing;
a card reader disposed in the housing and electronically coupled to at least the microprocessor, configured to read an ATM card;
a screen disposed in the housing and electronically coupled to at least the microprocessor, configured to display ATM transaction options;
a cash dispenser disposed in the housing and electronically coupled to at least the microprocessor;
a millimeter-wave radar transmitter disposed in the housing and electronically coupled to at least the microprocessor, wherein the radar transmitter is configured to provide a radar field in front of the housing with a height, depth, and width;
a radar receiver disposed in the housing and electronically coupled to at least the microprocessor, wherein the radar receiver is configured to receive radar reflections from one or more synthetic objects belonging to a user within the radar field;
an analog-to-digital signal converter disposed in the housing and electronically coupled to at least the microprocessor and the radar receiver, wherein the signal converter is configured to convert analog radar reflections to digital data;
non-transitory memory disposed in the housing and electronically coupled to at least the microprocessor, wherein the non-transitory memory is configured to:
store the analog radar reflections;
store the digital data; and
store an operating system;

a communication circuit disposed in the housing and electronically coupled to at least the microprocessor, wherein the communication circuit is configured to receive and transmit the digital data; and
a digital signal processor disposed inside the housing and electronically coupled to at least the microprocessor, the signal converter, and the non-transitory memory, wherein the digital signal processor is configured to:
identify the one or more synthetic objects belonging to the user within the radar field;
analyze any movement of the one or more synthetic objects within the radar field using a Doppler method;
convert the movement of the one or more synthetic objects into gestures or writing symbols; and
translate the writing symbols into words, numerals, or symbols;, wherein the operating system is configured to:
display on the screen a plurality of transaction options for the user;
translate one or more gestures by the user within the radar field selecting at least one transaction; and
process the at least one transaction.
