RFID Tracking Glossary

Pallet tracking refers to the clear identification and monitoring of pallets across defined stages in warehousing, goods receipt, transport and internal material flows. In the RFID environment, pallets are usually labelled with an RFID tag and automatically registered in the system at read points. This makes it possible to trace location, movements and processing status without manual postings. Pallet tracking creates greater transparency in the traceability of load carriers and goods movements. The automatic tracking of pallets reduces search effort, improves inventory visibility and stabilises material flow.

Paperless production refers to the digital organisation of production processes without paper-based documents in the ongoing workflow. Orders, processing statuses and feedback are provided, updated and processed digitally. It is part of digitalisation because information remains available within the process without media discontinuity and can be used directly. Paperless production  supports a continuous process flow and a more reliable information base in production. Employees and systems access current data directly and avoid unnecessary search effort and transfer errors.

A passive transponder is a transponder without its own battery and uses the energy from the field of an RFID reader to transmit data. This design is usually compact, robust and economical, but generally achieves shorter read ranges than an active transponder. A passive transponder is primarily used where many objects need to be identified reliably and without contact at fixed read points, such as containers, load carriers or workpieces. This technology is particularly suitable for processes with clearly defined read zones and high volumes in the ongoing material flow.

Polarisation describes the orientation of the electric field of an electromagnetic wave and influences how well a tag is detected by an RFID antenna. If the orientation of the antenna and tag matches well, the signal is transmitted more effectively. If the alignment is unfavourable, detection quality and read range decrease. This is particularly relevant in systems operating in the ultra-high frequency range, because moving or differently aligned objects cannot always be read equally well. The choice between linear and circular polarisation is therefore an important part of the technical design. The right alignment improves the stable detection of containers, cartons or pallets in real material flow processes.

Process automation refers to the technical execution of recurring workflows according to defined rules, without each step having to be triggered continuously by employees. In this context, capture events are passed directly to an interface or to downstream systems and processed further there. This creates coordinated workflows with clear status changes, a lower level of manual intervention and consistently usable information. The term covers not only the identification of objects, but also the digital triggering, transfer and processing of process steps across multiple stations. The automated continuation of events shortens response paths and relieves workloads at workstations in manufacturing and intralogistics.

Process reliability describes the dependable execution of a workflow with a consistently correct outcome. A process is considered reliable when the intended steps take place in the correct sequence, information is clearly available, and deviations do not distort the subsequent workflow unnoticed. The key point is therefore not only that data is captured, but that statuses, postings and handovers remain traceable and consistent. A stable identification process and clean data processing support exactly this dependability. High process reliability ensures that goods, containers or workpieces move through the process without incorrect assignment and without unnecessary interruptions.
