    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.
