Antenna for use with vault, reads data stored in radio frequency identification tag, which indicates closed or opened condition of vault, in which between walls of vault and antenna at pre-estimated position ferrite is arranged

摘要

The antenna (2) reads data stored in a radio frequency identification tag, which indicates a closed or opened condition of a vault. A ferrite (1) is arranged at a pre-estimated position between the antenna and the walls of the vault. A balancing electronics (3) optimizes the reading of the data. An evaluation electronics (4) processes the signals received from the transponder.
