The invention provides a gate
machine. The gate
machine comprises a first side engine body, a second side engine body, a
ticket and identity card detecting device, a first gate
machine door, a second gate machine door, a third gate machine door, an
identity recognition device and a
stream guidance door, wherein the second side engine body and the first side engine body are arranged in a spaced mode to form a gate machine channel, the
ticket detecting device is arranged at an entrance end of the gate machine channel and is used for detecting
ticket and identity card information of a
passer, the first gate machine door, the second gate machine door and the third gate machine door are arranged at intervals along the gate machine channel, the first gate machine door is used for blocking or opening the gate machine channel; the
identity recognition device is arranged between the first gate machine door and the third gate machine door, and is used for recognizing the identity information of the
passer, and the
stream guidance door is arranged on the first side engine body which is on one side of the gate machine channel and is located between the first gate machine door and the second gate machine door, and is used for guiding the
passer to leave the gate machine channel from the
stream guidance door. The invention further provides a gate machine set. The gate machine and the gate machine set can achieve the unification of 'human, ticket, and identity card', the passer can be effectively preventing from tailing after a person ahead and entering the gate machine, and forcibly breaking through the gate machine, and thus the traversing order of the gate machine is improved.
