A DEVICE THAT HAS TWO DATA CARRIERS

摘要

A device having two data carriers for the transfer of information at both low frequencies (Khz, Mhz) and microwave frequencies (Ghz). The invention is characterized in that it comprises a permanently sealed unit in the form of a card which accommodates both a microwave-based first data carrier having a first readable and/or readable and writable register, and an inductive second data carrier having a second register which can be read and/or read and written by means of induction at low frequencies, wherein the two data carriers are separated physically from one another.
