摘要

A security system comprising, in use a memory device, and a read/write unit to read data from and/or to write data to the memory device. The memory device comprises a body having a substantially planar form, and further having an. interface connector (e.g. a USB connector) in use projecting from one edge of the polygon and occupying a predetermined position relative to two mutually spaced outermost edges of the polygon having a predetermined distance between them. The read/ write unit has: (a) an entrance slot to receive at least' partially said body, (b) mutually spaced engagement means within the unit for engagement of said body, (c) an interface slot socket to receive and be couplingly connected to the projecting connector of a said inserted body, said socket occupying a position relative to said mutually spaced engagement means in correspondence with the said predetermined position of the connector.
