Vehicle parking barrier access control system

A vehicle parking barrier access control system, comprising:

• a barrier to passage of a vehicle traveling for ingress to or egress from a restricted vehicle parking area;
• a smart switch operatively associated with the barrier, the smart switch configured for operation with a wireless connection protocol device to communicate over a short-range wireless communication link;
• an access code source-providing medium making available to a vehicle parker a set of one or more sources of access code information to enable opening of the barrier, the access code information being made available to the vehicle parker as the vehicle approaches or is present at the barrier to commence creation of a parking session with no need for parking session preregistration, each source in the set making available an access code adapted for interaction with a gate App operating on a wireless-connection enabled mobile smart device associated with the vehicle parker seeking to open the barrier, the mobile smart device configured for communication over the short-range wireless communication link with the smart switch and over a long-range wireless communication link with a server to which a wireless connection protocol device is operatively connected and on which the system stores vehicle parking transaction information, and, in response to communication from the vehicle parker of access code information available from the set of one or more sources, the gate App cooperating with the server to create the parking session while the vehicle is present at the barrier;
• and
• a time-based, one-time password (TOTP) of time-limited validity generated by the server upon the creation of the parking session to verify that a barrier opening transaction is authorized by the server, the server configured to transmit, during initiation of the barrier opening transaction, the TOTP to the gate App for verification by the smart switch, the TOTP transmitted to the gate App being valid for a short amount of time that is limited to cause the gate App to develop for response by the smart switch an authorization signal in accordance with the access code, allow the gate App to forward to the smart switch the TOTP to verify its authenticity and thereby allow response by the smart switch to the authorization signal to enable opening of the barrier to passage by the vehicle, and thereafter conclude the barrier opening transaction to prevent sharing of the TOTP with another vehicle parker aiming to open the barrier.
