Information processing method, related equipment and system

The embodiment of the invention provides an information processing method, related equipment and a system. The method comprises the steps that a terminal establishes connection with a smartwatch; the terminal receives an electrocardiogram and fingerprint information of a user, sent by the smartwatch, and then judges whether the electrocardiogram is matched with a preset electrocardiogram or not; when the electrocardiogram is matched with the preset electrocardiogram, the terminal matches the fingerprint information with preset fingerprint information; when the fingerprint information is matched with the preset fingerprint information, the terminal records and sends attendance checking information of the user to the smartwatch. By means of the method, a user can view the attendance information of the above-mentioned user through the smartwatch, attendance checking can be completed through a wireless technology in the whole process, therefore, attendance checking can be improved, and in the attendance checking process, better sanitation is achieved, and the phenomenon of card punching replacement can be prevented.
