The invention relates to a near field communication module (3) for exchanging data via a near field communication network (8). It has: a first receiving and transmitting unit (32) for transmitting and receiving the data in a first data format (13) via a near field antenna (30) connected to the first receiving and transmitting unit (32); a second receiving and transmitting unit (33) for transmitting and receiving the data in a second date format (APDU) and having a unit (4) connected to the near field communication module (3); and a conversion unit (34) for converting the data from the first data format (13) into data of the second data format (APDU) and vice versa. The near field communication module (3) has a marking unit (31), wherein the marking units (31) marks the data by using a connection of the connected unit (4) to the second receiving and transmitting unit (33). The invention further relates to a communication terminal having a near field communication module, to the use of the module (3) in a portable data carrier (5) and to a method for marking data in a near field communication module (3).
