SIM CARD Serial Protocol

Hi all

I am an Embedded Engg, I am planning to come out with my own version of Turbosim, I need help to find the serial protocol of SIM Card, I have already built the Flexiable PCB with controller, I only need the protocol to build the complete system. Any kind of inputs are welcome

The ETSI 11.11 and ISO 7816-3 should be a good start

I almost simulated the protocol, Now working on the code, should be able to complete it in a weeks time
