SYSTEMS AND METHODS OF PROVIDING AND VALIDATING DIGITAL TICKETS

Systems and methods for facilitating use of physical tokens in a transit system are disclosed. In one implementation, a method for facilitating use of physical tokens by a server includes generating a token identifier and generating, using a private key associated with the server, a cryptographic signature based on the token identifier. The method further includes transmitting the token identifier and the cryptographic signature to a token dispenser. The token dispenser is configured to dispense a physical token, and the physical token is configured to provide the token identifier and the cryptographic signature to a token validator. The method also includes receiving, from the token dispenser, (i) a first indication that the physical token is dispensed, (ii) selection of a fare type, and (iii) dispenser context data including a dispense location, associating the token identifier with the selected fare type and the dispenser context data, and receiving, from the token validator, a second indication that the physical token is being validated. The second indication (i) is transmitted after the token validator verifies the cryptographic signature using a public key associated with the server, and (ii) includes the token identifier provided by the physical token and validator context data including a validation location. Furthermore, the method includes identifying the fare type associated with the token identifier, accessing, based on the fare type, a set of restrictions governing use of the physical token, and determining whether the physical token is valid based on (i) the accessed set of restrictions, (ii) the validator context data associated with the token identifier provided by the physical token, and (iii) the dispenser context data received from the token validator. Moreover, the method includes transmitting a communication to the ticket validator indicating whether the physical token is valid, wherein the ticket validator, in response to receiving the communication, outputs an indicator whether the physical token is valid.
