The invention relates to a 
fingerprint punched-card 
machine capable of detecting physiological parameters of a 
human body. The 
fingerprint punched-card 
machine basically comprises an MCU, a fingertip 
information acquisition unit, a reflection-type pulse oximeter 
signal acquisition unit and a weighing sensor unit, wherein the fingertip 
information acquisition unit consists of a 
fingerprint acquisition unit and a transmission-type pulse oximeter 
signal acquisition unit; the MCU, the fingertip 
information acquisition unit, pulse oximeter 
signal sensors and the weighing sensor are connected with one another; the fingerprint acquisition unit acquires the fingerprint information, attendance is finished, the two paths of pulse oximeter signal sensors acquire the pulse 
waves and transmit pulse 
waves to the MCU for performing 
blood pressure measurement; and the weighing sensor under the feet measures the weight information and transmits the information into a single-
chip MCU. Meanwhile, a 
wireless transceiver module in the single-
chip transmits the acquired information to a 
mobile phone and a computer, and the data is conveniently stored. According to the 
machine disclosed by the invention, fingerprint attendance can be realized, the 
blood pressure and weight data can be simultaneously measured, the data is transmitted into the detected 
mobile phone, and the physical condition of a person is conveniently known.
