Internal SD Card Information Information about an SD card is encoded in its internal card registries. One of these is the Card Identification (CID) Register, a 16 byte code that contains information that uniquely identifies the SD card, including the card serial number (PSN), manufacturer ID number (MID) and manufacture date (MDT). A genuine SanDisk SD memory card always contains a serial number on the lower back of the card. The location of the serial number will vary depending on memory card type and manufacturer. If you have a SanDisk card, take a look at this article, which details the possible location of serial numbers on its storage products. To ensure the proper operation of the SD card, the SD CLK signal should have a frequency in the range of 100 to 400 kHz. To communicate with the SD card, your program has to place the SD card into the SPI mode. To do this, set the MOSI and CS lines to logic value 1 and toggle SD CLK for at least 74 cycles. After the 74 cycles (or. The SD and micro SD card modules allow you to communicate with the memory card and write or read the information on them. The module interfaces in the SPI protocol. To use these modules with Arduino you need the SD library. This library is installed on the Arduino application by default.

Internal SD Card Information
Information about an SD card is encoded in its internal card registries. One of these is the Card Identification (CID) Register, a 16 byte code that contains information that uniquely identifies the SD card, including the card serial number (PSN), manufacturer ID number (MID) and manufacture date (MDT). The CID register is set when the card is manufactured and cannot be changed after it is set. (According to SD card specification the information is only to be written once, however if a card does not conform to the specification this information could be changed!)
How to read the CID from an SD card
One way to read the CID is to use a laptop with an SD card slot. Card readers in laptops are usually connected directly through the PCI bus (or IDE bus). This will not work through a USB card reader because the command to retrieve the card information is intercepted and not understood by card readers. Not all computers with built-in card slots will work, some internal card readers are connected through a USB bus.
Assuming you have the proper hardware, there are several methods you can use to get the card information. With Linux, reading the internal SD card information is simple. Insert the card and look under /sys/block/mmcblk0/device/ (this location may change depending on your platform, it may be mmcblk1 or in a different location). Under this location you will see several attributes available that include the CID and CSD registers and the information inside it.
To view the CID, the command is cat /sys/block/mmcblk0/device/cid (the exact location may be different)
What information is in the CID?
The following information is stored in the CID:
| Name | Field | Linux attribute* | Description |
|---|---|---|---|
| Manufacturer ID | MID | manfid | Assigned by SD-3C, LLC. |
| OEM/Application ID | OID | oemid | Identifies the card OEM and/or the card contents. Assigned by SD-3C, LLC. |
| Product Name | PNM | name | 5 characters long (ASCII) |
| Product Revision | PRV | hwrev, fwrev | Two binary coded decimal (BCD) digits. Each is four bits. The PRV is in the form x.y. The PRV can also be found by using the hwrev and fwrev, where x=hwrev and y=fwrev |
| Serial Number | PSN | serial | This 32 bit field is intended to be read as an unsigned integer |
| Manufacture Date Code | MDT | date | Manufacture date is stored in the form yym (offset from 2000) |
| CRC7 checksum | CRC | 7 bit code used for checking errors in the card register |

List of Common Manufacturer ID (MID)
Manufacturer ID (MID) are assigned by the SD Assoication (SD-3C LLC). They consider this information confidential so an official list is not published.
The following list was compiled by reading the CID on numerous SD cards. Many card brands are produced by OEM suppliers, and the MID and OEMID may reflect this, or in some cases they appear to show the producer of the card controller. For example, PNY cards have been found with 0x000028 and BE (Lexar) or 0x000027 and PH (Phison).
