The invention concerns an identifier and a method in identification of an object. The identifier comprises a source of light (13), from which a strip of light of uniform thickness is produced onto the face of the object to be identified. Said strip of light or beam of light (12) produced onto the face of the object is monitored by means of a colour differentiation device (17), which receives the ray of light reflected from the face of the object. By means of signals produced by means of the colour differentiation device (17), colour codes are produced out of different face areas of the monitored object, which codes are compared with color codes of objects to be identified stored in the memory of the central unit of the device, in which connection of the object is identified on the basis of the comparison. |
