We identify and examine products according to identity, presence, situation, tolerance and quality. For this purpose we use different identification systems such as video cameras, magnetic strip readers and chip reading facilities or bar code readers. Also physical features like weight or form can be examined. With the systems we use, products with centrally stored identification numbers and specifications or information contained in databases can be compared with the recorded data and their correctness checked. Further features which we check include bar code, chip, magnetic strip, Multi ID Reading, OCR, RFID, labels and other quality features. Modules for the quality control can be integrated in various systems for the production of passes and passports as well as in the further processing. Through a comprehensive quality control faulty productions can be avoided and the highest product security can be guarantee.
