Abstract: 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.

Abstract: Systems and methods for providing and validating a digital ticket are disclosed. In one implementation, a ticket validating device includes one or more processors configured to obtain a digital ticket, a ticket-server signature, and a device signature from a ticket holder's device. The digital ticket is obtained from a ticket server by the ticket holder's device, the ticket-server signature is generated based on the digital ticket using a private key associated with the ticket server, and the device signature is generated based on the digital ticket using a private key associated with the ticket holder's device. The one or more processors are further configured to validate the digital ticket. The validation of the digital ticket includes verifying the ticket-server signature using a public key corresponding to the private key associated with the ticket server, and verifying the device signature using a public key corresponding to the private key associated with the ticket holder's device.

Abstract: Techniques for Check-In/Be-out (CiBo) and Be-in/Be-out (BiBo) using mesh networks are disclosed. In one implementation, an access control system includes a mesh network. The mesh network includes a set of mesh nodes disposed proximate to a gate to an access-controlled area and a master mesh node communicatively coupled to the set of mesh nodes. The master mesh node is configured to determine whether a device is near the gate based on a strength of a signal received at one of the set of the mesh nodes from the device. The system further includes a validator communicatively coupled to the master mesh node and a backend system. The validator is configured to: receive an indication from the master mesh node that the device is near the gate, determine, based on the indication, whether the device is authorized to enter or exit through the gate, and transmit a result of the determination of whether the device is authorized to enter or exit through the gate to the backend system.

Abstract: Systems and methods for associating and delivering context-aware content to mobile devices via a programmable trigger that is based upon changes in the mobile device's location. A user's mobile device can interact with trigger-based tracking devices (e.g., Bluetooth beacons, NFC, etc.) which provides location information to the user's mobile device, such location information being relative to the tracking device. Embodiments of the present disclosure also comprise a server that delivers targeted content (e.g., text, graphics, audio, video, etc.) to mobile devices when a user is at a certain geographical location. The content delivered is associated with a context of the user's location which is based in part on the location information received relative to the tracking device. In some embodiments, the content delivery does not require a separate mobile application for the content provider but can be embedded inside transit-related information of a mobile application of a transit agency.
