RFID Tracking Glossary

In the RFID environment, ultra-high frequency refers to a frequency range used for contactless data transmission, especially where longer read ranges and the rapid capture of many objects are required. Compared with high frequency, this range is particularly suitable for automated processes in logistics, shipping and internal material flow. The actual detection quality is strongly influenced by the conditions at the place of use. The frequency range  is therefore an important factor in the technical planning of RFID systems. Ultra-high frequency is used when goods, containers or pallets need to be identified automatically without line of sight and with a high detection density.

User memory is a writable memory area on a transponder in which application-specific data can be stored in addition to the fixed identifier. This may include status information, process values or internal assignments that need to be available directly on the object. The size of this area and whether it can be read or written depend on the chip type and the standard used. User memory therefore supplements the actual identification with usable additional information on the object, but does not usually replace central data processing in the background. The direct storage of selected process data on the tag supports the clear assignment of containers, workpieces or load carriers at changing capture points.
