Two-way communication system initiated by machine readable code

A system for providing communication between first and second electronic devices, the system comprising:

• a server,
• a first software application executable on the first electronic device in communication with the server,
• a second software application executable on the second electronic device in communication with the server,
• a first display that includes a first machine readable code thereon,
• wherein when the first machine readable code is processed by the first electronic device a first user interface is displayed on the first electronic device and a second user interface is displayed on the second electronic device, wherein the first user interface includes a first predetermined input, wherein selection of the first predetermined input prompts an initial indicator on the second electronic device, wherein the initial indicator is the change of an indicator member associated with the first user interface from a non-indication state to an indication state, wherein the first user interface includes a first user interface variable input configured to transmit a user variable message to be displayed on the second user interface, wherein the second user interface includes at least a first predetermined input, wherein selection of the first predetermined input prompts a first predetermined message to be displayed on the first user interface, wherein the second user interface includes a second user interface variable input configured to transmit a responder variable message to be displayed on the first user interface.
