1. A data carrier having an electric circuit,which includes circuit parts of at least one interface, which circuit parts are adapted to receive data in the form of data blocks, each data block including delimiter data and useful data, andwhich includes delimiter data detection means, which are adapted to detect delimiter data of a data block and to generate and to supply at least one useful data start signal, which at least one useful data start signal can be generated and supplied upon detection of the delimiter data, andwhich includes data test means, which are adapted to test the data for data errors, characterized in that the delimiter data detection means are adapted to continually re-detect the delimiter data of a data block and to generate and to supply the useful data start signal also after the supply of the useful data start signal, wherein the data carrier is configured for inductive coupling with a second device when placed within a predetermined, contactless distance of the second device, the second device supplying power for operation of the electric circuit.
