Abstract
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).
