Keypad dulcet authentication cardless payment technology

A cardless payment architecture comprising:

• a point-of-sale (“POS”) device comprising:
• a keypad configured to receive a sequence of keypresses as authentication for a cardless transaction;
• a processor configured to record the sequence of keypresses and tag each keypress with a timestamp;
• a keypress controller configured to determine from the sequence of keypresses:
• a number of keypresses;
• a frequency of each keypress, the frequency comprising a rate of keypresses per unit of time;
• and
• a time-delay between each keypresss, the time-delay calculated based off of the timestamp tagged to each keypress;
• and
• the processor further configured to:
• store the sequence, the timestamp, the number of keypresses, the frequency and the time-delay as authentication data for the cardless transaction;
• encrypt the authentication data;
• and
• transmit the encrypted authentication data to the secure payment network for verification;
• the secure payment network comprising:
• a machine-learning (“ML”) pattern identifier configured to:
• decrypt, by the secure payment network, the authentication data;
• and
• identify, by the secure payment network, a pattern to the sequence of keypresses based on the determined number of keypresses, the determined frequency and the determined time-delay;
• and
• a pattern verification controller configured to verify that the identified pattern matches to a stored pattern associated with an entity, the matching to authenticate the cardless transaction, the verifying comprising confirming that:
• the number of keypresses is equal to a stored number of keypresses;
• the frequency of the keypresses is within a pre-determined range of a stored frequency of keypresses;
• and
• the time-delay between each keypress is within a pre-determined range of a stored number of time for each time-delay.
