The invention provides a teaching sign-in method and terminal. Through the recognition by a radio frequency recognition device, first label code of a radio frequency label on a student school card isobtained; the time for recognizing the first label code by the radio frequency recognition device is a first time point; a face image of a student corresponding to the first label code is obtained from a database; whether the student performs sign-in or sign-out is judged through video information shot by a first camera and a second camera which are arranged on a school door in the preset time range before the first time point; the corresponding sign-in or sign-out information and the corresponding first time point are sent to a parent end corresponding to the first label code so that the parent can conveniently know the school reaching and school leaving time; the problem that the parent cannot timely know whether the child goes to school or leaves the school in time is solved; by using the method, the student can be effectively supervised and urged to go to school or go home in time.
