15. SD and MS connectors (10-pin SD, MS)*
These connectors support the sophisticated memory devices called
Secure Digital (SD) memory card and Memory Stick (MS). These
devices facilitate fast and secure downloading of all types of digital files
such as photos, music, news, and movies. You may also use SD and
MS to directly record audio, video, and still photos. The SD and MS are
non-volatile devices so they do not require power to retain the
information stored in them.
*
The SD and MS connectors may or may not be mounted depending on SI requirements.
You need an SD/MS reader to use the SD and MS devices. The SD,
MS, and the SD/MS reader are optional items and may be purchased
separately.
14. Smart Card Reader connector (14-1 pin SMARTCARD) (optional)
This connector accommodates a Smart Card Reader that allows you to
conveniently make transactions such as financial, health care,
telephony, or traveling services through a Smart Card user interface
software.
