Card Reader is one of the computer hardware that is useful for reading memory card (SD Card). Card Reader can also be interpreted as a small device whose use is connected to a USB port for reading portable media cards.
Card Reader can accept one or multiple media card formats, such as SD, xD or Compact Flash. If your computer does not have a built-in card reader, of course you will need a card reader to transfer data from your media card to the hard drive or vice versa
For speed reading and data transfer, card reader has a speed so good with an average reading speed of 37. 4MB / s and an average write speed of 17. 6MB / s, which definitely makes this card reader feasible for you to have in support of your activities to move or copy external memory files you have
The function of card reader is connect memory card to laptop through usb laptop or computer where data stored in memory can do activity of sharing and receiving file each other. Therefore, by using card reader, of course the data can be opened and moved according to our wishes.
In addition, this card reader function is as a tool that acts as a removable storage device for a variety of equipment similar to a digital camera, camcorder, cell phone, audio player and so on that can read the memory card
If you access the file through a computer device, the card reader will also send an electrical signal to the media card by contact at the end of the card case. Electrical signals used to read data stored on a media card.
Like all forms of solid-state memory, media cards use transistor circuits to record data. These transistors are suitable for representing binary data, the basic form of all computer files.
When the electric current that is sent from the USB reader card can pass through the transistor, the section is read into one. Otherwise, it's returned to zero. The card reader compiles the results and sends them to a computer program asking for info from the card. The program can use binary data to create visual representations of data, such as image documents or text or even audio.

How to Use Card Reader
- Insert your memory card in the card reader hole and adjust the type of memory card you use
- Plug USB cable card reader on USB port
- Let the computer system to do the detection and installation of the card rider driver, in general card reader is Plug and Play
- To see if the card reader is read, please check the windows explorer menu and search for my computer.
- If it is read, then you can do the activity of sending files or vice versa
