The invention relates to smartcard under SecureMMC standard, the card being connected to a host through a MMC bus and being compliant to ISO/IEC7816 standard. According to the invention, the card is multi-application operation capable and a determined number N of commands can be processed in the card in parallel, being the number of logical channels the card can support, the card has means for using a command or a response which is encapsulated in an information field of a bloc frame, said bloc frame also having at least a prologue field for at least identifying the source node application and the destination node application in a NAD datum, and the card has means for as long as the number p of active commands in the card is lower than N and none is completed, the card is in Secure_ldle state, an active command being a command which is being processed and that when the number p of active commands in the card is equal to N, the card switch to Secure_ln_Progress state, the finishing of any command switching the card to Secure_Data_Available state, a transition from Secure_ldle state to Secure_Data_Available state being added and a transition from Secure_Data_Available state to Secure_Data_Available state being added. |
