A user identification system comprises user equipment 101, such as a smartphone or other mobile device, having a user identity application. A physical token 103, such as a machine-readable travel document (MRTD), is connected in use to the user equipment 101 via a wired data connection. The physical token 103 comprises a secure element 106, such as a SIM, storing user identity data, and a secure responder 110 storing security data, wherein the secure element is used to authenticate the secure responder of the physical token using the security data. If authentication of the secure responder 110 is achieved, the identity data is provided to the user identity application for communication by the user equipment 101 to a remote device. The physical token 103 may be detachably connected to the user equipment 101 so as to allow it to be used with other user equipment. The physical token 103 may be provided as a case for the user equipment. The system may be arranged as an electronic identity card, such as an electronic passport, or e-passport. |
