A geo-proximity Vehicle Alert and Access System, VAAS, comprising: a cloud based server having a Global Positioning System, GPS, based proximity system having one or more processors configured to execute instructions to control and track a package exchange process, to speed up a package delivery and pick-up process, and to ensure security for the package exchange process; a GPS-based delivery application, downloadable or otherwise electronically distributed to a client device from a database in the cloud based server, wherein said client device is 1) a first client device installed in a package carrier's vehicle, or 2) a second handheld client device that travels with a driver of a package carrier's vehicle, where the GPS-based proximity system is configured to receive both current GPS coordinates of said client device associated with said package carrier's vehicle from said client device and current GPS coordinates of a target vehicle for monitoring the distance between said vehicles for at least one of i) package delivery to the target vehicle and ii) package pick up from the target vehicle, wherein the current GPS coordinates of said package carrier's vehicle is transmitted from said GPS-based delivery application, wherein the GPS coordinates of the target vehicle are transmitted from a telematics module of the target vehicle to the GPS-based proximity system, where the GPS-based proximity system is further configured to send one or more commands 1) to the target vehicle to wake-up said telematics module in the target vehicle while in a close proximity established by a first threshold distance between the package carrier's vehicle and the target vehicle, 2) to the telematics module in the target vehicle to give an alert from the target vehicle while in a close proximity established by a second threshold distance between the package carrier's vehicle and the target vehicle, 3) to the telematics module in the target vehicle to unlock a door including a trunk of the target vehicle, and 4) established by a fourth threshold distance to the target vehicle to lock the doors of the target vehicle after receiving a confirmation of the package exchange process from the client device associated with the package carrier's vehicle. a cloud based server having a Global Positioning System, GPS, based proximity system having one or more processors configured to execute instructions to control and track a package exchange process, to speed up a package delivery and pick-up process, and to ensure security for the package exchange process; a GPS-based delivery application, downloadable or otherwise electronically distributed to a client device from a database in the cloud based server, wherein said client device is 1) a first client device installed in a package carrier's vehicle, or 2) a second handheld client device that travels with a driver of a package carrier's vehicle, where the GPS-based proximity system is configured to receive both current GPS coordinates of said client device associated with said package carrier's vehicle from said client device and current GPS coordinates of a target vehicle for monitoring the distance between said vehicles for at least one of i) package delivery to the target vehicle and ii) package pick up from the target vehicle, wherein the current GPS coordinates of said package carrier's vehicle is transmitted from said GPS-based delivery application, wherein the GPS coordinates of the target vehicle are transmitted from a telematics module of the target vehicle to the GPS-based proximity system, where the GPS-based proximity system is further configured to send one or more commands 1) to the target vehicle to wake-up said telematics module in the target vehicle while in a close proximity established by a first threshold distance between the package carrier's vehicle and the target vehicle, 2) to the telematics module in the target vehicle to give an alert from the target vehicle while in a close proximity established by a second threshold distance between the package carrier's vehicle and the target vehicle, 3) to the telematics module in the target vehicle to unlock a door including a trunk of the target vehicle, and 4) established by a fourth threshold distance to the target vehicle to lock the doors of the target vehicle after receiving a confirmation of the package exchange process from the client device associated with the package carrier's vehicle.
