A contrast sensor for evaluating identification markings and a method of evaluating identification markings on detecting objects using a contrast sensor, having at least one light transmitter and at least one light receiver, with the light receiver having a single photodiode; having a control and evaluation unit for evaluating the light receiver signal of the light receiver, and having an output for a sensor signal that is formed by the control and evaluation unit on the basis of the light receiver signal, wherein the identification marking has lettering or a marking; an elongate illumination field is projected by the light transmitter onto a region of the identification marking narrow in the direction of movement; and the control and evaluation unit compares a reception signal sequence having a plurality of contrast transitions with a stored reception signal sequence and outputs the sensor signal in dependence on the comparison.
