  • at the server, receiving a request from a first client device for a numeric representation for a credential, the request comprising (i) a credential identifier that identifies the credential and (ii) a first user identifier that identifies a first user and is associated with the credential identifier;

    responsive to the request from the first client device;

    generating, at the server, a first numeric representation for the credential, wherein the first numeric representation for the credential expires at a first time;

    associating, at the server, the first numeric representation for the credential with the credential identifier and the first user identifier; and

    transmitting, from the server, a message including the first numeric representation for the credential to the first client device;

    at the server, receiving a first validation request from a processing system associated with a credential authority, wherein the first validation request comprises a first value;

    before the first time, accessing, at the server, the first numeric representation for the credential using the first value; and

    at the server, responsive to determining that the first value from the first validation request matches the first numeric representation for the credential, transmitting to the processing system, a first validation response indicating that the credential is associated with the first user.
