A data carrier adapted to receive data (D) in the form of data blocks, which data blocks include delimiter data (SD) and (ED) and useful data (UD), includes delimiter data detection means adapted to detect delimiter data (SD) and (ED) of a data block and to generate and supply at least one useful data start signal (SOF; SOFA, SOFB), in which also after the supply of the useful data start signal (SOF; SOFA) the delimiter data (SD) and (ED) can be re-detected continually and the useful data start signal (SOF; SOFB) can be generated and supplied.
