Electronic Data Interchange (EDI)
EDI is a form of computer-to-computer data interchange that is a form of electronic mail. It mainly involves business documents and helps in accomplishing transactions e.g. sending invoices.
Organisations have an agreed format for the electronic documents so that they are recognised by all parties to the transaction.
Example: EDIFACT (Electronic Data Interchange For Administration, Commerce and Transport).

ELECTRONIC FUNDS TRANSFER at POINT OF SALE (EFTPOS): Aims
to handle, electronically, the high volume, low value transactions which make up the bulk of payments by number which banks currently have to handle and process in paper form. EFTPOS systems integrate the retailer‘s POS system, which may comprise bar- code scanning or a sophisticated computerised cash register, with an electronic payment system.
