Semi-passive transponder

A semi-passive transponder is a transponder with its own battery that supplies the internal electronics or sensing components. However, data transmission does not take place via a continuously self-generated radio signal, but through the field of an RFID reader. This design therefore sits between a passive transponder and an active transponder. It combines low energy consumption with longer battery life and often enables more stable detection under demanding conditions. Such tags are mainly used when, in addition to clear identification, measured values or condition data also need to be provided. The technology is particularly suitable for containers, operating equipment or sensitive objects that must be detected reliably and monitored at the same time.
