摘要:
A method for controlling a session of a self-service terminal utilizes an image capture device that captures image frames for identification of a user's face. If a face is identified, a model is temporarily associated with that face. The face is monitored until the user closes the session, thereby generating possible events. When the user leaves the terminal during the session, or a new face assumes the position formerly held by the previous face, the result of the comparison results in the closing of the session. In the case that the same user remains in place until the end of the session, the result of the comparison allows the reduction of requests for confirmation of user identification data.

Provided is a process for producing chlorosulfonyl isocyanate by reacting sulfur trioxide with cyanogen chloride, which comprises feeding sulfur trioxide and cyanogen chloride simultaneously to the reaction zone and maintaining the temperature of the reacting zone at 10.degree. to 50.degree. C. This is a commercially very simple process and can produce chlorosulfonyl isocyanate with high purity in high yield.
