Closer Examination
One of the things that makes this card special is the integrated USB 2.0 connector that allows this card to connect to a PC without an SD-card reader. As you can see the card looks just like a regular SD-card with the protective cap on. If you remove the protective cap the USB connector becomes visible, compared to a normal memory stick it lacks the metal shell that helps the user insert it correctly.
As you can see the card looks pretty standard with the protective cap on. The construction of the card seems pretty sturdy even though the card can be split up into two pieces.
With the protective cap off this card looks like a fusion between a USB memory stick and an SD-card, which of course is exactly what it is. I really like the concept of the Secure Digital Dual, because it can be used as an SD-card while still maintaining functionality of a USB memory stick. It's very convenient because you don't need a SD-card reader in order to get information out of the card, all you need is a USB 2.0 port on your PC or laptop.
Besides from being able to transform into a USB memory stick the card also has a write protect function which can be enable by manipulating a little bar on the side of card. This is a pretty standard feature, but it's nice to have if you have some important stuff on the card that you want to keep.
The card looks standard with the protective cap on, also the layout with the write lock placed towards the top on the left side of the card is standard.
On the picture above you can see how the card looks when inserted correctly into a USB port. Inserting the card rotated into the USB port is possible, but it will not harm the card, it will simply not be detected.
