FIELD: control means.
SUBSTANCE: invention relates to means of controlling access to objects. In system using switch and access control module as verification features of refractive, refracting properties of non-duplicated objects of random shape, transparent for electromagnetic radiation with a certain wavelength, randomly oriented relative to the electromagnetic radiation beam. As method of recognition of unique refractive properties of objects of random shape and, accordingly, verification of key, direction is used through transparent object or objects of random shape, included in the beam of the electromagnetic radiation beam from the electromagnetic radiation source placed in the access control module by directing said beam to the electromagnetic radiation sensor, which enables to fix for the subsequent analysis the characteristic features of said beam, and thus, verify the key for making a decision on granting access or denial of access to the protected object.
EFFECT: technical result is higher security of objects.
