A method for accessing a smart card from a host device, the smart card being connected to the host device via a telecommunications card, the telecommunications card having a command interpreter for interpreting host device commands and a modem with associated smart card reader for enabling the telecommunication and user identification the modem being only accessible to the host device via the command interpreter, the method including: (a) providing an access command on the host device, the access command instructing the command interpreter to pass on any attached command originating from the host device to the smart card reader; (b) attaching an application command to the access command and forwarding both to the command interpreter; (c) performing the application command on the smart card reader; (d) storing a response given by the smart card to the application command in a first buffer which is accessible towards the host device.

Method for accessing a smart card from a host device

A method for accessing a smart card (SIM) from a host device (TE) via a telecommunications card (MT), the telecommunications card (MT) comprising a command interpreter (TA) for interpreting host device commands and a modem (ME) with associated smart card reader, the modem (ME) being only accessible to the host device via the command interpreter (TA), the method comprising the steps of: (a) providing an access command (AT+CSIM) on the host device, instructing the command interpreter (TA) to pass on any attached command originating from the host device (TE) to the smart card reader; (b) attaching an application command (APDU) to the access command (AT+CSIM) and forwarding both to the command interpreter (TA); (c) performing the application command (APDU) on the smart card reader; (d) storing a response given by the smart card (SIM) in a first buffer which is accessible towards the host device (TE).
