An electrical interface module (IM) has a memory device MEM) for storing data and an integrated interface (IO) that provides data to an external reading device (RW). The electrical interface module (IM) contains a carrier (2) on which the memory device (MEM) and the integrated interface (IO) are arranged, the electrical interface module (IM) can exchange data and/or power with other electrical interface modules (IM) in the vicinity via the integrated interface, and adjacent electrical interface modules (IM) form a logical data bus via the integrated NFC interfaces, which can be addressed and/or controlled by at least one head module or a master module with a higher control and/or monitoring device.
