An arrangement for data transfer between a desk top personal computer (1)
and a peripheral or other data processing device (7) comprises a transfer
pad (5) which comprises two conductive plates (8, 9) which is connected to
the personal computer (1) via a lead (6). The peripheral or other data
processing device (7) has a transfer pad (11) which comprises two
conductive pads (12, 13) attached to or forming part of the lower wall of
its housing. For data transfer to occur the two transfer pads are brought
into close proximity so that they provide a capacitative coupling between
the personal computer (1) and the peripheral or other data processing
device (7).
