Zusammenfassung:	The invention relates to a data exchanging device (1), particularly of a tachograph (DTCO), for exchanging data in a manipulation-proof manner between a card (3) and the data exchanging device (1). Said data exchanging device (1) comprises a logic unit (4) which monitors data exchange between the card (3) and the data exchanging device (1). The aim of the invention is to secure especially the also legally sensitive recorded data of a tachograph from being manipulated during data exchange while reliably recognizing and registering manipulation attempts. Said aim is achieved by configuring the logic unit (4) such that a manipulation incident is recorded in a memory (5) of the data exchanging device (1) and/or the card (3) when the card (3) is not physically or logically present.
