SD cards are used to provide expandable storage to a huge range of devices form cell phones and cameras, to gaming systems and laptop computers. Every SD card that is made must have a CID in order to interface with another device. THE CID is a special identifying code that is unique to each card, working in the same fashion as a serial number. THE CID is not usually displayed anywhere on the device, and few manufacturers provide a way of retrieving this information. With the help of a free, open source application, you'll be able to read The Cid of any SD card in less than five minutes.
