The abbreviation RFID stands for "Radio Frequency Identification". In addition to barcode capture, this identification technology has become firmly established in production and (intra-)logistics. RFID can be used to identify objects precisely and without contact. This is done using a transponder and a read/write unit, also known as a reader, which generates an electromagnetic field and can be used either as a mobile or stationary unit. The transponder attached to the goods acts as an information carrier, the reader reads the codes it contains and transmits them to the warehouse management system or warehouse management system. Communication or data transmission between the transponder and reader takes place in the ultra high frequency (UHF) range by radio.
A central advantage of RFID applications is the option of being able to record and match several objects in parallel in a batch - for example, when collecting goods. In the field of paperless picking, this technology enables automated control and direct feedback of data. At the same time, orders can still be updated during processing. Additional identification and control work is not required.
