UPDATE (Feb 16, 2023):We learned the company which manufactures this product now offers the ability to write the CID value as well as write protect the Secure Digital media.
GetUSB.info just posted a nice article on how to read the CID (or PSN) from an SD card, or product serial number. Some also call this reading the CID number from an SD card. The CID number is a unique identifier number or serial number created on the SD or microSD media at the time of manufacturing. This is a number which cannot be changed or manipulated by the host computer.
The CID number is most often used for vendors or manufacturers to lock in software to a specific device. Since the CID number cannot be changed or modified, it’s a great way to prevent unauthorized distribution or content or software.
Some manufacturers require to read the CID number from SD media before the software is published and this is what GetUSB.info talks about. For a full description of the article, make the jump: How to read CID number from SD media.
Here is a snap shot of the CID reading tool for 20 SD devices:
The CID number is composed of the following values:
- Manufacturer ID: This is an 8-bit code that identifies the manufacturer of the SD card.
- OEM/Application ID: This is an 16-bit code that identifies the OEM or the application for which the SD card was designed.
- Product Name: This is a 32-bit ASCII code that specifies the product name of the SD card.
- Product Revision: This is a 8-bit code that specifies the product revision of the SD card.
- Serial Number: This is a 32-bit code that specifies the unique serial number of the SD card.
- Manufacturing Date: This is a 12-bit code that specifies the manufacturing date of the SD card.
- CRC: This is a 7-bit code that is used to verify the integrity of the CID number.
The CID number is typically used by SD card host devices to verify the authenticity of the SD card and to ensure that it is compatible with the host device.

The biggest reason for the USB modem is lack of required drivers, as it’s either preinstalled on the device or installs directly from the device.Â In addition, the USB modem is portable and easily swapped between work and home locations. ABI asks whether embedded modem modules in new computers or the recent interest in personal hotspot routers (a la MiFi) can overtake the popularity of USB dongles. Research associate Khin Sandi Lynn points out that, â€œIn the long run, more devices are looking for a network to connect to. The wireless modem market can solve this in many ways â€“ different form-factors, air interface protocols, and increased attention to style and cultural interests.â€ ABI webpage.

Sorry for the rant, but to boost the value of the phone with a $20 8GB microSD card isn’t all that impressive. Interested to hear more about the Blackberry Storm?Â You can read the following reviews: Verizon Storm. Continue Reading
We selected chips that have complete documentation publicly available, such as the ARM-based Samsung S3C2410 SOC. We added a debug port with complete access to JTAG and a serial console. This phone is designed for open-source development.With a sporty 640×480 LCD that holds a beautiful 283 dpi the visual from the Neo 1973 should be amazing. Unlike the first version of the iPhone the Neo 1973 will have 128MB RAM with 64MB NAND flash and an expandable microSD slot (bonus 512MB card ships with the phone). So hackers, gadget hounds and side project guru’s I think this is worth a closer look. At just $300 – what a deal. This first run of release units is more geared towards developers so don’t expect any retail phones to hit BestBuy just yet. OpenMoko Neo 1973 home page Continue Reading
