Glossary
Readers
Readers ensure fast, secure data transfer between mobile data storage units and higher-
level systems. The data, energy included, are transmitted across an electromagnetic
alternating field. This principle enables contact-free data transmission, ensures high
industrial compatibility and works reliably in the presence of contamination or through non-
metallic materials.

SIMATIC RF identification systems control and optimize material flow and
production sequences. They identify reliably, quickly and economically, use non-contact
data communication technology, and store data directly on the product. They are also
resistant to contamination.

Transponder
An invented word from transmitter and responder. Transponders are used on the product,
the product carrier, the object, or its transport or packaging unit, and contain production and
manufacturing data, i.e. all application-specific data. They follow the product through
assembly lines, transfer and production lines and are used to control material flow.
Because of their wireless design, transponders can be used, if necessary, at individual work
locations or manufacturing stations, where their data can be read and updated.
