A transponder card comprises a carrier substrate arranged without interlayers between two protective plastic plates, a planar frame antenna, on the substrate with two supply connections and a conductor track connecting the supply connections, and an integrated circuit with two antenna connections. The antenna connections are electrically connected to the two supply connections and the integrated circuit is arranged such that the conductor track does not run through between the antenna connections. The conductor track may include at least two first conductor track segments and at least one second conductor track segment. Each end of the second conductor track segment is electrically connected to a respective first conductor track segment. The second conductor track segment crosses at least one of the two first conductor track segments at least once and is electrically insulated from the first conductor track segment by at least one nonconductive separation element.
