An electronic transaction system (1) and method are described for performing a transaction between a merchant who provides goods or services and a user. In an embodiment, the transaction system includes a merchant terminal (3) which receives user identification data (in the form of a credit card or debit card) for a user associated with the transaction and transmits an authorisation request (to a merchant acquirer server 5). A transaction server receives the authorisation request and retrieves user account data associated with the user identification data. The user account data includes a mobile communications device number associated with the user so that the transaction server (7) can send a communication to the user's mobile communications device requesting that the user authorise the transaction. Once authorised by the user, the transaction server (7) sends an authorisation signal back to the merchant terminal (3). |
