## Abstract

A method of acquiring access rights to conditional access content. The method comprises receiving an access right on a first terminal through a first communication channel; storing said access right in said first terminal; sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to Which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; verifying, by said content provider, the authenticity of said access right using said piece of information concerning the access right; and when there has been a successful verification, marking said access right as used, and sending said conditional access content to at least one terminal linked to said account. The first terminal using near field communication technology (NFC) during at least one transfer of said access rights.

## Claims

### Claim 1

A method of acquiring access rights to conditional access content, said method comprising the steps of;
receiving an access right on a first terminal through a first communication channel;
storing said access right in said first terminal;
sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; and
receiving said conditional access content by at least one ten' final linked to said account;
wherein said first terminal uses near field communications (NEC) during at least one operation for the transfer of said access rights.
