The production of card reader
When mentions card reader, a lot of people will immediately think of this product is produced with the digital camera, but now it is no longer limited to digital cameras, but is extended to more areas. multiple card reader is a device for reading data, but it not only can support the reading of the data also support the write of data. The initial design ideas are mainly generated in order to compensate for the defects of the digital camera data output. Early USB interface is not popular, so the output of the digital camera is connected with the computer's serial port. Serial data transmission speed is very low, if the data is copied to the hard disk, it would have to spend a lot of time. Therefore, the card reader is produced.
The uses of card reader
With the development of digital products, such as MP3, PDA, which push the development of the reader powerfully. The MP3 standard 32M or 64M flash already cannot meet our needs, so the addition of 128M flash memory has become our standard configuration, but if we are to copy MP3 songs to flash, it can be achieved only through the MP3 player, and this time we need a dedicated connection, drivers and software to complete. In addition to providing convenient data transfer, the memory card readers is also used in the mobile data storage. Later, with the development of computer technology, especially the launch of the WINDOWS operating system, the software volume increases in a geometric grade, so the standard 1.44M floppy is too small. Mass storage leads to the desire of the increasing popularity of the "magnanimous" memory, the hard drive, CD-ROM drive, and a variety of compressed storage devices. People are more accustomed to the mobile office with a light and easy to carry large reserves data "carry-save "device.
