10 SC Reader Example

AN2284

38/40

PwdFile will be created with PIN1 enabled for

read and write access:

SC_Handler (SC_CREATE_FILE, (u8 *) PwdFile, 40, SC_PIN1_W | SC_PIN1_R,

NULL_PARAM, &SC_state, &u16_status, response);

If the user verifies PIN1 for read/write operations,

PwdFile can be accessed. When the user

tries to verify a PIN, the related Pwd has to be specified. In this example the

following 8byte password is associated with PIN1:

Pwd={"1", "1", "1", "1", "1", "1", "1", "1"}

SC_Handler (SC_VERIFY, (u8 *) Pwd, PWD_LENGHT, NULL_PARAM,SC_VERIFY_PIN1,

&SC_state, &u16_status, response);

After that he can be selected:

SC_Handler (SC_SELECT_FILE, (u8 *) PwdFile, NULL_PARAM,

NULL_PARAM,NULL_PARAM, &SC_state, &u16_status, response);
