1. A method of authorizing a fluid dispense, the method comprising:
generating, at a near field communication (NFC) programming unit, dispense-authorization data for a fluid dispense event;
writing, by the NFC programming unit, the dispense-authorization data to an NFC data source;
placing the NFC data source within an operable range of an NFC receiver disposed on a fluid dispensing meter having a meter body, a handle, and a trigger;
providing, by the NFC receiver, the dispense-authorization data to a processor of the fluid dispensing meter, the dispense-authorization data including a desired fluid type;
recalling, from the memory of the fluid dispensing meter, initial configuration data configured to indicate a fluid type associated with the fluid dispensing meter;
comparing, by the processor, the desired fluid type from the dispense-authorization data and the fluid type associated with the fluid dispensing meter from the initial configuration data;
determining, by the processor, an authorization status of the fluid dispense event based on the comparison of the desired fluid type from the dispense-authorization data and the fluid type associated with the fluid dispensing meter from the initial configuration data; and
controlling, with the processor, a trigger control mechanism of the fluid dispensing meter between an activated state and a deactivated state based on the comparison of the desired fluid type from the dispense-authorization data and the fluid type associated with the fluid dispensing meter from the initial configuration data.
