Adapter for beverage dispenser

A method of operating a beverage dispensing machine, the machine comprising:

• a powered line;
• a neutral line;
• a valve connected to each of the powered line and the neutral line;
• a beverage dispensing nozzle in fluid communication with the valve;
• a circuit board, wherein the circuit board comprises a switch and a processor thereon, and a reader connected thereto, and wherein the powered line is connected to the circuit board at a first point, and the neutral line is connected to the circuit board at a second point;
• an electrical circuit comprising the valve, the powered line, the neutral line, the circuit board, and the switch;
• and
• a splash panel, wherein the beverage dispensing nozzle is on the first side of the splash panel, and the circuit board with the switch and processor thereon is connected to a second side of the splash panel that is opposite the first side,
• the method comprising the steps of:
• presenting a credential to the reader;
• communicating the credential from the reader to the processor;
• comparing the credential to a to a set of approved credentials;
• if the credential matches one of the approved credentials, setting set the switch to a closed position, thereby closing the electrical circuit and allowing beverage to flow through the valve and the beverage dispensing nozzle;
• and
• if the credential does not match one of the approved credentials, setting the switch to an open position, thereby opening the electrical circuit and not allowing beverage to flow through the valve and the beverage dispensing nozzle.

A method of retrofitting a beverage dispensing machine, the machine comprising:

• a powered line;
• a neutral line;
• a valve connected to each of the powered line and the neutral line;
• a beverage dispensing nozzle in fluid communication with the valve;
• and
• a keyport, wherein each of the powered line and the neutral line are connected to the keyport, wherein the keyport has a first position and a second position, wherein in the first position the powered line, the neutral line, the valve, and the beverage dispensing nozzle complete a first circuit, and in the second position, the first circuit is disrupted,
• the method comprising the steps of:
• disconnecting each of the powered line and the neutral line from the keyport;
• connecting the powered line to a circuit board at a first point;
• connecting the neutral line to the circuit board at a second point, wherein the circuit board has a switch thereon and a reader connected thereto;
• and
• forming a second circuit comprising the valve, the powered line, the neutral line, the circuit board, and the switch,
• wherein the reader is configured to read a credential provided by a user,
• wherein the processor is configured to receive the credential from the reader and compare the credential to a set of approved credentials,
• wherein if the credential matches one of the approved credentials, the processor is configured to set the switch to a closed position, thereby closing the second circuit and allowing beverage to flow through the valve and the beverage dispensing nozzle, and
• wherein if the credential does not match one of the approved credentials or no credential is presented to the reader, the processor is configured to set the switch to an open position, thereby opening the second circuit and not allowing beverage to flow through the valve and the beverage dispensing nozzle.
