The invention discloses a high-flow people flow unmanned security check system. The device system comprises a base and a main shell fixed to the upper side of the base through a supporting block. Wherein, wherein a card storage device is arranged in the main shell; a threaded lifting mechanism is arranged in the card storage cavity and used for transmitting needed cards upwards. The card is transmitted rightwards through the card outlet device; a clamping device located on the right side of the card outlet device is arranged in the main shell. The traffic card rotating rightwards is clamped through the clamping air bag; the opening of the device is opened through transmission between the connecting rod and the gear set in the process of moving towards the opening in the right side of the device; card issuing process, according to the device, the linkage of the device is improved through the matching relation between transmission, it is guaranteed that the traffic card is effectively clamped through the material characteristics of the air bag, meanwhile, the outer surface of the traffic card is not damaged, the sealing performance of the device is kept when no vehicle passes through, solar energy is converted through the photovoltaic panel, and therefore commercial power consumption is reduced.
