Identification

Bar codes have become a fixed part of today's global economy. We are all familiar with them from the supermarket checkout, but the identification of goods and materials by universally used bar codes also controls many processes in logistics and in many production lines. The area of application of readers is correspondingly broad – from mobile hand-held operation to high-speed scanners for industrial applications.

With two-dimensional codes, light and dark dots are arranged in a matrix. As a result, considerably more information can be stored in the same area than with a one-dimensional bar code. Thus, 2D-identification is ideally suited for additional applications, such as parts tracking, in which codes are directly affixed to the work piece.

Everything clear even with poor visibility

Compared to conventional identification systems, RFID technology has one decisive advantage: no direct "visible contact" is necessary between the read/write unit and the transponder to read out information. An RFID system consists of a read/write unit, a transponder and the associated software. Information from the transponder is detected by means of electromagnetic waves. As a result, these systems can be used practically and reliably under even the most adverse conditions.
