A connector for data transfer is provided. The connector comprises a connector body having a coupling mechanism, and a communication module for communicating with a first data processing device and a second data processing device. The communication module is arranged with respect to the connector body such that upon the coupling mechanism being coupled to the first data processing device, the communication module is positioned with respect to the first data processing device to effect close-range wireless communication between them to enable a data transfer between the first and second data processing device. A data processing system and a method of carrying out data transfer between a first and second data processing device are also provided.
