What is an SD card?
The Secure Digital Card is a further development of the MultiMedia
Card. The SD card can transfer the data faster and it is equipped with
a special copy protection system, which prevents unauthorised copies
from the card to other storage media. If this system is activated, the
cards can only be replayed on devices that support this copy
The SD card can also be used without copy protection. In this case it
reacts like a MultiMedia Card and can be used in every device equipped
with an SD card slot.
