Specially programmed computing devices being continuously configured to allow unfamiliar individuals to have instantaneous real-time meetings to create a new marketplace for goods and/or services

A computer-implemented method, comprising:

• electronically receiving, by each computing device of a plurality of computing devices associated with a plurality of users, software which, when being executed, cause each computing device of the plurality of computing devices to display a plurality of instances of a specifically programmed graphical user interface (GUI);
• wherein the plurality of users is at least one hundred concurrent users;
• wherein each instance of the GUI is configured to display a real-time updatable meeting information representative of a direct electronic proximity-based communication between at least two computing devices of the plurality of computing devices associated with at least two users who desire to meet at a particular location to engage in a transaction of at least one good, at least one service, or both, whose marketable value lasts for a period of 30 seconds to 60 minutes;
• wherein the meeting information real-time updatable comprises:
• 1) a first data representative of the particular location;
• 2) a second data representative of at least one unique user authentication identifier, which has been assigned to:
• i) a particular computing device of the at least two computing devices or
• ii) the at least two computing devices;
• and
• 3) a third data representative of a real-time adjustable visual indicator, allowing the least two users to visually identify each other computing devices, wherein the real-time adjustable visual indicator has been uniquely assigned based, at least in part, on at least one other visual indicator being assigned to at least one other computing device to be located in a visual vicinity of the particular location at which the at least two users to meet;
• electronically receiving, by each of the at least two computing devices of the at least two users, an indication that the at least two users who desire to meet to engage in the transaction of the at least one good, the at least one service, or both, whose marketable value lasts for the period of 30 seconds to 60 minutes;
• electronically establishing, by each of the at least two computing devices of the at least two users, the direct electronic proximity-based communication between the at least two computing devices;
• dynamically determining, in real time, by each of the at least two computing devices of the at least two users, the first data, the second data, and the third data of the meeting information;
• and
• dynamically controlling, by each of the at least two computing devices of the at least two users, based on the meeting information, a visual appearance of the GUI to facilitate the at least two users to meet at the particular location.
