Method and system for automatically passing through gate

The invention provides a method and system for automatically passing through a gate. The method comprises the following steps of acquiring a request for passing through the gate; responding to the request of passing through the gate, reading the induction information, obtaining balance information, and judging whether the balance is greater than a threshold value or not; if the balance is not greater than the threshold value, not opening the gate; if the balance is greater than the threshold value, acquiring second face information, comparing the second face information with the first face information, if the second face information is consistent with the first face information, opening the gate, and otherwise, not opening the gate. Therefore, automatic money deduction and gate passing canbe realized, and through the combination of the recognition card and the face recognition technology, the problem of illegal use of a swiping card for passing through a gate is solved, and the manualparticipation link is red
