1. An RFID liquid dispenser and measuring process comprising:
detecting, by a radio frequency identification (RFID) card reader of a particular product storage and dispensary unit configured to dispense a particular liquid product, a supported RFID card that is positioned nearby the RFID card reader;
capturing, by the RFID card reader when the supported RFID card is positioned nearby the RFID card reader, data comprising an identifier (“identifier data”) of the RFID card;
providing, by the RFID card reader, the identifier data to a dispenser controller of the particular product storage and dispensary unit, wherein the dispenser controller is configured to verify the identifier data to determine whether the supported RFID card is authorized for use in dispensing the particular liquid product;
transmitting, by the dispenser controller when the identifier data is verified and the supported RFID card is authorized, liquid dispensing control data to (i) a fluid pump of the particular product storage and dispensary unit that is configured to pull the particular liquid from a product reservoir and (ii) a dispenser valve of the particular product storage and dispensary unit that is configured to open to release the particular liquid pulled from the product reservoir by the fluid pump;
dispensing, only while the supported RFID card is positioned nearby the RFID card reader and the supported RFID card is detected by the RFID card reader, the particular liquid through the dispenser valve while the fluid pump pulls the particular liquid from the product reservoir;
measuring and tracking, by a flow meter of the particular product storage and dispensary unit, volumetric liquid flow data for a flow of the particular liquid being dispensed;
retrieving, by the dispenser controller, the volumetric liquid flow data measured and tracked by the flow meter;
storing, by the dispenser controller, the volumetric liquid flow data in a memory unit of the particular product storage and dispensary unit; and
wirelessly transmitting, by the dispenser controller through a WiFi transceiver of the particular product storage and dispensary unit, the volumetric liquid flow data and the identifier data of the supported RFID card to a checkout interface device connected to a common network.
