Abstract: The invention relates to a system and method for controlling access to contents. The system comprises a network for distributing encrypted content, a receiver (100) for receiving such content, at least one mobile terminal (200) for communicating with the receiver (100) through a short-range wireless interface, for example NFC, means for sending the Identifier of the desired Content, Product or Service and a user identification from the smart card of the mobile terminal (200) to a purchase platform (300) and means for sending the information necessary for decoding the encrypted content to the smart card of the mobile terminal (200). The mobile terminal (200) is configured to send said information through the wireless interface to the receiver (100) and the receiver (100) decodes the encrypted content with the aid of the information received from the mobile terminal (200). Smart cards with SCWS technology are used.
