The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that, among other things, authorize initiated exchanges of data in real-time based on dynamically generated tokenized data. For example, an apparatus may receive first positional data identifying a first geographic position of a client device and based on the first positional data, the apparatus may determine a value of a parameter characterizing an exchange of data between the client device and a terminal device disposed proximate to the client device during a temporal interval. The apparatus may transmit data requesting a pre-authorization of the data exchange to a computing system, which perform operations that pre-authorize the data exchange in accordance with the parameter value and transmit a digital token representative of the pre-authorized data exchange to the terminal device. The digital token may be valid during the temporal interval and may include a cryptogram associated with the client device.
