SD Card Duplicator With Streaming Data

You’ve probably 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 we’ll look at an SD Card Duplicator, which allows you to data stream unique material to each card.

Typically, a user would replicate the same material to SD cards if they intended to generate several copies of the same information. However, my clients who utilize SD media (or microSD media) want to not only duplicate the identical information to each card but also transfer unique data to each card.

Let Us Look Little Deeper With An Example:

It is fairly usual for organizations that create map data to likewise wish to secure their mapping information. Maps are expensive to create and can contain sensitive information that a corporation wants to keep private. So, when it comes time to employ an SD Card Duplicator to generate hundreds or thousands of copies, a protection system must be incorporated with the duplicating solution.

The use of the card’s CID number is a standard approach 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 the card around. It is not feasible to clone or duplicate the CID number… it is a value that is intended to be read-only. In addition to the unique number, reading the CID number from the card requires certain vendor instructions.

Because Nexcopy employs specific vendor instructions to obtain the CID value, it is feasible to read the CID number with an SD Card Duplicator from Nexcopy.

So here’s what a mapping firm can do:

  • Encrypt the mapping data.
  • Comprises of a text file with the decryption code for the maps.
  • Include the actual card’s CID number in the aforementioned text file.
  • Because CID numbers are unique to each card, write the unique key code text file to each card.

During the duplicating process, the SD Card Duplicator allows the user to export CID numbers in bulk. When CID numbers are exported in bulk, the organization can develop a script to generate 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 carries the CID number and key code to each card.

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

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

The standard was launched in August 1999 as an enhancement over Multi Media Cards (MMCs) by a partnership of SanDisk, Panasonic (Matsushita), and Toshiba, and has subsequently become the industry standard.

In January 2000, the firms also formed the SD Association (SDA), a non-profit organization dedicated to promoting and developing SD Card standards.
