Digital data interchange devices and networks

摘要

A self-service terminal ( 12 ) forming part of a SST network is provided with an infra-red port ( 30 ) enabling digital data interchange to take place between the SST ( 12 ) and a portable electronic digital device ( 20 or 90 ) having a corresponding matching port ( 82 or 92 ) which is presented to the SST ( 12 ). The portable device ( 20 or 90 ) may be any device having an electronic digital data memory. Examples include PDAs ( 20 ), digital cameras ( 90 ) and cellular mobile phones. The SST network is connected to the Internet thus enabling data interchange to take place between the portable device ( 20 or 90 ) and any Internet address. Thus the SST ( 12 ) can be used to interchange data between a customer's PDA ( 20 ) and his home computer ( 16 ).
