    Abstract: A carrier structure including a carrier, an antenna structure on the carrier and a reception region designed for removable reception of an RF chip. The reception region is arranged relative to the antenna structure in such a way that inductive coupling to the antenna structure is enabled when the RF chip is arranged in the reception region. An inductive blocking element on the carrier blocks communication with the RF chip using the antenna structure in a first position of the inductive blocking element. In a second position of the inductive blocking element, the inductive blocking element enables communication with the RF chip using the antenna structure.
