When it comes to data duplication to SD cards, the saying "the devil is in the details" could not be more appropriate. The focus of today's post is an SD Card Duplicator, which allows you to data stream unique material to each card.

If a user wants to produce several copies of the same content, they will often copy the same material on SD cards. My clients who use SD (or microSD) media, on the other hand, wish to transmit not just the identical material but also unique data to each card.

Let's Look At A Specific Example:
Companies that develop map data are typically concerned about the security of their mapping information. Maps are expensive to make and may include sensitive information that a company wants to keep confidential. When utilizing an SD Card Duplicator to make hundreds or thousands of copies, the duplicating solution must have a protective system.

The card's CID number is a standard way for establishing security on SD card media. The CID number is a value that is kept on an SD card's "read-only memory," and it is unique to each card and follows it everywhere. The CID number cannot be copied or duplicated since it is a read-only variable. Aside from the unique identifier, retrieving the CID number from the card itself necessitates specific vendor instructions.
Nexcopy SD Card Duplicators can read the CID value since Nexcopy uses vendor-specific instructions to do so.

So here's what a mapping company can do for you:

• Protect the mapping data by encrypting it.
• Include a text file with the decryption code for the map.
• Include the physical card's CID number in the above-mentioned text file.
• Because the CID number on each card is unique, attach the unique key code text file to each card.

The SD Card Duplicator allows the user to export CID numbers in bulk when duplicating. When CID numbers are exported in bulk, the organization can write a script that creates key code text files that can only be decrypted by the card with the correct CID value.

The SD Card Duplicator's last step is to write the encrypted map data to all of the SD cards (or microSD cards) and then do a second duplicate run to perform the unique data stream of the encrypted file that contains the CID number and key code to each card.

The end-user will need to create some custom scripts or batch files, but the Nexcopy SD Card Duplicator will handle the majority of the duplicator operation.

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

SanDisk, Panasonic (Matsushita), and Toshiba partnered in August 1999 to design the standard as an improvement over Multi Media Cards (MMCs), and it has since become the industry standard.

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