SD Shield Concern

For my engineering project, I’m not only displaying data on the epaper display(http://www.sparkfun.com/products/10150), but I’m also writing to an SD Memory Card (http://www.sparkfun.com/tutorials/172). My main concern is the number of pins available to use? Can someone tell mehow many pins the SD Memory Card Shield will use?

Looking at the schematic http://www.sparkfun.com/datasheets/DevT … ematic.pdf the SD card uses pins D8 (CS) D11 (MOSI) D12 (MISO) and D13 (SCK)
