Information prompting method, device and equipment and computer readable storage medium

The invention discloses an information prompting method, device and equipment and a computer readable storage medium, and the method comprises the steps: collecting a first face image corresponding toa first user when the first user is detected at a first preset position, and carrying out the face authentication of the first face image; if the first face image does not pass the face authentication, determining whether a tool carried by the first user belongs to an in-library tool or not through an RFID tag; and if it is determined that the tool carried by the first user belongs to the in-library tool through the RFID tag, and it is detected that the first user passes through the tag reading area, triggering an alarm. According to the invention, face authentication is carried out on the face image of the user, the target tool RFID tag carried by the user is detected, and combined logic judgment is carried out on face image identity authentication login, RFID tag reading and infrared induction judgment, so that
