Abstract
The invention concerns a device (10) featuring an optical reader (12) for printed codes capable of transforming the information of a code printed on an object such as a label into digital data, the object being equipped with a radiofrequency system featuring an antenna (27) and a chip (28) connected together. According to a main characteristic of the invention, the device features a radiofrequency dialog unit (15) designed to encode the chip (28) with digital data read from the printed code and to compare the digital data encoded in the chip with information from the printed code.
