Hi Henrik, thanks for the responce. To be honest I already saw the link, but I'm skeptical because I dont really understand how it works(not simple for me). But I'm willing to try it out. I need to incorporate the sdcard because I'm trying to create a "coin operated computer rental app" I want later to save the number of coins and date/time per transaction. I also want to learn the EEPROM stuff but I was thinking about the capacity and since SDCARD can be quite cool (if I manage to incorporate it). I will try the link and post the results.

regards,
tacbanon
