The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that, among other things, authorize initiated exchanges of data based on tokenized data characterized by a limited temporal or geographic validity. For example, an apparatus may receive a first signal that includes first information identifying a first geographic position of a client device. The apparatus may also obtain a digital token representative of a pre-authorization of a data exchange between the client device and a terminal device during a corresponding temporal interval. The terminal device may, for example, be disposed within a geographic region that includes the first geographic position of the client device. The apparatus may generate and transmit a second signal that includes the digital token to the client device. In some examples, the apparatus may transmit the second signal being through a programmatic interface associated with an application program executed by the client device.
