Claim 11:
12. A method for providing contact-minimized interaction with an ATM, said method comprising:
sensing, at the ATM, an ATM card;
identifying, at the ATM, a customer associated with the ATM card;
activating, at the ATM, a Doppler millimeter-wave radar transmitter;
transmitting, from the radar transmitter, a radar field;
prompting, by the ATM, the customer to write within the radar field an authentication passcode;
receiving, at a radar receiver, Doppler radar reflections from one or more synthetic objects belonging to the user within the radar field;
digitizing, at the ATM, the Doppler radar reflections;
processing, at a digital signal processor (“DSP”) at the ATM, the Doppler radar reflections;
identifying, at the DSP, at least one target of the customer, wherein the at least one target is all or a portion of the one or more synthetic objects;
resolving and analyzing, at the DSP, movement of the at least one target;
translating, at the DSP, the movement of the at least one target into gestures, words, numerals, or symbols;
sending, from the ATM to an authentication server, the gestures, words, numerals, or symbols;
authenticating the customer, at the authentication server, by matching the gestures, words, numerals, or symbols to gestures, words, numerals or symbols associated with an authentication passcode of the customer;
informing, by the authentication server, the ATM when the customer has correctly provided the authentication passcode;
displaying, at the ATM, a plurality of transaction options for the customer, in response to the customer correctly providing the authentication passcode;
selecting, at the ATM, at least one transaction through at least one gesture by the one or more synthetic objects in the radar field; and
processing, at the ATM, the at least one transaction.
