Biometric caching

An identification station, comprising:

• a non-transitory storage medium storing instructions;
• and
• at least one processor that executes the instructions to:
• obtain a digital representation of a biometric for a person;
• in response to determining that the digital representation of the biometric does not correspond to data in a local cache:
• determine a time window;
• store the digital representation of the biometric in the data in the local cache for the time window;
• use the digital representation of the biometric that is stored in the data in the local cache and an identification system computing device that stores biometric data and associated identity information for multiple people to perform an identification of the person;
• and
• perform a processing of a payment;
• and
• in response to determining that the digital representation of the biometric does correspond to the data in the local cache, omit repeating the processing of the payment.

A system for biometric caching, comprising:

• an identification system computing device;
• and
• an identification station that:
• obtains a digital representation of a biometric for a person;
• in response to determining that the digital representation of the biometric does not correspond to data in a local cache:
• stores the digital representation of the biometric in the data in the local cache for a time window;
• transmits the digital representation of the biometric to the identification system computing device;
• and
• performs a check-in of the person for an appointment;
• and
• in response to determining that the digital representation of the biometric does correspond to the data in the local cache, omit repeating the check-in of the person for the appointment.
