Title:
ATTENDANCE MACHINE USING PALM VEIN RECOGNITION
Document Type and Number:
WIPO Patent Application WO/2020/048010
Kind Code:
A1
Abstract:
An attendance machine using palm vein recognition. The attendance machine comprises a power supply, a power supply drive circuit, a palm vein collection circuit, an SD card, an SD card interface circuit, an ARM processor of a model equal or superior to cortex A8, an LCD display circuit, an LCD display screen, an audio output circuit, a loudspeaker, an RS232/485 communication conversion circuit and an access controller, wherein the power supply is connected, via the power supply drive circuit, to the ARM processor of a model equal or superior to cortex A8; the palm vein collection circuit is connected to the ARM processor of a model equal or superior to cortex A8; the SD card is connected, via the SD card interface circuit, to the ARM processor of a model equal or superior to cortex A8; the ARM processor of a model equal or superior to cortex A8 transmits intercom visual information to the LCD display screen via the LCD display circuit, and sends an audio prompt by means of the loudspeaker via the audio output circuit; the ARM processor of a model equal or superior to cortex A8 controls logical communication between palm vein recognition and a circuit; the ARM processor of a model equal or superior to cortex A8 is provided with a near-infrared LED camera; and a visitor is subjected to palm vein image extraction and digital processing.
