SD Card Duplicator With Unique Data Streaming

You’ve heard the quote “the devil is in the details” and when it comes to duplication of data to SD cards, nothing can be more true. Today we talk about an SD Card Duplicator which provides the ability to data stream unique content to each card.

Typically a user would duplicate the same content to SD cards because they intend to make many copies of the same content. However, my companies who use SD media (or microSD media) want to not only copy the same content to each card, but also copy unique data to each card.

Let us dig a little deeper with an example:

It is very common for companies who generate map data also want to protect their mapping information. Maps are expensive to make and often times hold proprietary information that company wants to protect. So when it comes time to use an SD Card Duplicator to make hundreds or thousands of copies, it is required to have a protection scheme included with the duplication solution.

A common method to provide protection on SD card media is using the CID number of the card. The CID number is a value which is put into “read only memory” of an SD card and that CID number is unique to each card and follows the card around. It is not possible to copy or duplicate the CID number… it is a value which is designed to only be read. In addition to the unique number, there takes specific vendor commands to read the CID number from the card itself.

With an SD Card Duplicator from Nexcopy it is possible read the CID number because Nexcopy uses the special vendor commands to read the CID value.

So this is what a mapping company can do:

  • Encrypt the mapping data
  • Include a text file with the decryption code for the maps
  • Include the CID number of the physical card in the text file mentioned above
  • Since CID numbers are unique to each card, write the unique key code text file to each card

With the SD Card Duplicator the user can export the CID numbers in bulk during the duplication process. When the CID numbers are exported in bulk, the company can write a script to generate key code text files which can only be decrypted by the card which holds the correct CID value.

The final step of the SD Card Duplicator would be writing the encrypted map data to all the SD cards (or microSD cards) and make a second duplication pass to perform the unique data stream of the encrypted file which holds the CID number and key code to each individual card.

There is certainly some custom scrips or batch files which the end-user would need to write, but the bulk of the duplicator process would be done by the Nexcopy SD Card Duplicator.

SD Card Duplicator

Secure Digital (SD) is a proprietary non-volatile memory card format created by the SD Association (SDA) for use in portable devices.

The standard was introduced in August 1999 as an improvement over MultiMediaCards (MMCs) by a collaboration of SanDisk, Panasonic (Matsushita), and Toshiba, and has since become the industry standard.

In January 2000, the companies also established the SD Association (SDA), a non-profit organization, to promote and develop SD Card standards.

Read and Write CID Values From SD Media

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:

  1. Manufacturer ID: This is an 8-bit code that identifies the manufacturer of the SD card.
  2. OEM/Application ID: This is an 16-bit code that identifies the OEM or the application for which the SD card was designed.
  3. Product Name: This is a 32-bit ASCII code that specifies the product name of the SD card.
  4. Product Revision: This is a 8-bit code that specifies the product revision of the SD card.
  5. Serial Number: This is a 32-bit code that specifies the unique serial number of the SD card.
  6. Manufacturing Date: This is a 12-bit code that specifies the manufacturing date of the SD card.
  7. 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.

New 12GB microSDHC is 50% Storage Boost

12gb microsdhc sandisk cardSanDisk announced today a massive 12GB microSDHC card which is 50% larger in storage capacity than it’s previous model (8GB). So what does this mean?  It means our mobile devices are getting one step closer to becoming a storage medium for all sorts of data, phone related or not.  From MP3 files, video and data files … with 12GB of flash memory, quit a lot can fit.  To put things into perspective, the microSDHC can hold [about] 1,500 MP3 songs, 3,600 photos and 24.5 hours of video. If you haven’t used or seen a microSDHC card, make sure you stop off at your local computer store and take a look.  The size is incredibly small.  About the size of your pinky fingernail. Some background info:  The SDHC format applies to SD flash memory which is larger than 2GB is storage space.  The new 12GB microSDHC card conforms to the SD 2.00 specification and has the theoretical maximum storage capacity of 32GB. On a closing note, the new SanDisk microSDHC card has a transfer speed compatible with the Class 4 specification.  Too geeky for ya – let me sum it up: Continue Reading

A Proportionate SD Card

Gizmodo did a fun little pictorial about relative size of a SDHC card last week. This is what the new Toshiba 32GB SDHC card looks like when compared to the more common 1GB SDHC card. Good thing technology doesn’t work this way. I’d have one hell of a big cell phone just to accommodate more memory – then again, I don’t think I’ll need 32GB of data on my phone anytime soon.
