Introduction

Application area
MOBY identification systems support automatic, fast and reliable identification. The
important data accompany the product throughout the complete logistics and transport
process. When fitted to the item to be identified, data can be stored on the MDS contact-free
and either updated or read out contact-free at any point in the material flow process.
Different types of MDS can be selected to suit the specific application. Rugged transponder
construction supports use under harsh industrial conditions at high temperatures and makes
the MDS resistant to many chemical substances.
Design and function
The main components of the mobile data storage unit (MDS) are logic, antenna and
EEPROM. If an MDS moves into the transmission field of the SLG (write/read device), the
necessary power for all circuit components is generated and monitored by means of the
energy supply unit. The pulse-coded information is prepared in such a way that it can be
processed further as pure digital signals. The control unit handles the data and the check
routines.
