Abstract: The disclosure generally describes methods, software, and systems for processing information received from Internet of Things (IoT) devices, including a computer-implemented method in which information is received in a semantic recognition system (SRS). The information includes a device identifier (ID) of a first device, a payload containing information transmitted by the first device, and semantic information associated with the first device. A semantic model for the first device is determined by the SRS using the device ID and the semantic information. A digital twin representing the first device is generated by the SRS.

Abstract: An apparatus for communicating with a portable data carrier comprises a first communication interface, based on wireless data transfer technology, for receiving and/or transmitting data via a first communication channel, and a second communication interface, based on different contactless data transfer technology, for receiving and/or transmitting data via a second communication channel. A first software interface to the first communication interface via which an application program stored in the apparatus can communicate with the first communication interface. The apparatus has a second software interface via which the application program can communicate with the second communication interface, with the communication from the first software interface to the first communication interface, and vice versa, being passed via the second software interface.

Abstract: A transponder unit for transferring data to a reading device by modulation of an electromagnetic field includes a device for varying the data block size of the data by restricting the same or by modifying a clock signal, in dependence on a frequency difference between a clock frequency of a clock signal transferred from the reading device to the transponder unit, and a frequency generator frequency of a frequency generator of the transponder unit.
