A host-peripheral adaptor includes a host adaptor and a portable peripheral adaptor. The host adaptor includes a substantially flat peripheral-adaptor-side interface. The peripheral-adaptor-side interface is designed in a way that it is not easy to tamper with. The portable peripheral adaptor includes a host-adaptor-side interface that is designed to operatively connect to the peripheral-adaptor-side interface of the host adaptor. The portable peripheral adaptor also includes one or more peripheral-side interfaces for accommodating one or more peripheral devices such as a storage media. The portable peripheral adaptor and the host adaptor include a set of data lines and the host adaptor also includes circuitry for recognizing the specific type of a peripheral device and, based on its specific type, for setting a suitable communication path to transfer data between a host and the peripheral device.
