SD Card Duplicator With One Of A Kind Data Streaming

You’ve heard the expression “the devil is in the details,” and nothing could be more accurate when it comes to data duplication to SD cards. Today’s topic is an SD Card Duplicator, which allows you to data stream unique material to each card.

Typically, a user will replicate the same material on SD cards if they wish to generate several copies of the same content. However, my clients who utilize SD media (or microSD media) want to transfer not just the same material but also unique data to each card.

Let’s Take A Quicker Look At An Example:

Companies that create map data frequently seek to secure their mapping information. Maps are costly to create and can contain sensitive information that a corporation wants to keep private. When using an SD Card Duplicator to produce hundreds or thousands of copies, a protection system must be incorporated with the duplicating solution.

The CID number of the card is a standard mechanism for protecting SD card media. The CID number is a value that is stored in the “read-only memory” of an SD card, and it is unique to each card and follows it everywhere. The CID number cannot be copied or duplicated… it is a value that is intended to be read-only. In addition to the unique number, reading the CID number from the card itself requires certain vendor instructions.

Nexcopy SD Card Duplicators can read the CID number because Nexcopy employs specific vendor instructions to read the CID value.

So here’s what a mapping firm can do:

  • Encrypt the mapping information.
  • Include a text file with the map decryption code.
  • Include the physical card’s CID number in the text file specified above.
  • Because each card’s CID number is unique, attach the unique key code text file to each card.

During the duplicating process, the SD Card Duplicator allows the user to export the CID numbers in bulk. When CID numbers are exported in bulk, the organization can create a script that generates key code text files that can only be decrypted by the card that has the proper CID value.

The SD Card Duplicator’s last step would be to write the encrypted map data to all of the SD cards (or microSD cards) and 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.

There will undoubtedly be some custom scrips or batch files that the end-user must write, but the Nexcopy SD Card Duplicator will handle the majority of the duplicator process.

The SD Association (SDA) developed Secure Digital (SD) as a proprietary non-volatile memory card format for use in portable devices.

SanDisk, Panasonic (Matsushita), and Toshiba collaborated to establish the standard in August 1999 as an enhancement over Multi Media Cards (MMCs), and it has now become the industry standard.

The firms also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards.
