An electronic access control method for identifying a person, wherein an identification document is associated with the person, comprising: sensing an identification characteristic of the person in an access region on the basis of the identification document by means of an identification sensing device; transmitting the identification characteristic by means of the identification sensing device to a biometric sensing device; and sensing a biometric characteristic of the person by means of the biometric sensing device within the access region in response to the receipt of the identification characteristic in order to identify the person, wherein the electronic access control method comprises comparing the identification characteristic to the biometric characteristic by means of the biometric sensing device, characterized in that the sensing of the biometric characteristic of the person is performed prior to a passing through an entrance door in a transitional area between the entrance door and an exit door, wherein the entrance door, the transitional area and the exit door form an air lock, and wherein a sensing of the biometric characteristic is then again performed within the transitional area, albeit at a lower biometric characteristic comparison threshold, wherein the once again sensing of the biometric characteristic does not start until the entrance door behind the person is closed, so that no other person can enter into the transitional area after verification of the identification document, so that it can be ensured that the person whose identity had already been verified prior to entering is also the person who enters into the transitional area, wherein the electronic access control method comprises a sensing of the person in the access region by means of a person sensing device, which is designed as an infrared camera, wherein the sensing of the person in the access region includes also a liveness detection of the person in the access region by means of the person sensing device, wherein the liveness detection of the person is performed on the basis of a sensing of a pulse of the person and/or a sensing of a body temperature of the person, wherein the pulse and the body temperature of the person are sensed using the infrared camera, wherein the sensing of the person in the access region by means of the person sensing device is performed by using a predetermined body model or a predetermined motion model of the person, wherein the predetermined body model and/or predetermined motion model are derived from characteristics of human biomechanics, wherein the predetermined body model indicates static body characteristics of persons comprising a typical body size or typical body width, and wherein the predetermined motion model indicates dynamic motion characteristics of persons comprising a typical speed or typical acceleration of persons. sensing an identification characteristic of the person in an access region on the basis of the identification document by means of an identification sensing device;
