Some industrial automation distributors (like Radwell, PLC Center) offer a service where they clone a card you physically provide . You ship your working card, they make a copy, and ship both back. This is legal because you own the original IP.
There are two primary ways to handle MMC images: via TIA Portal/Step 7 (Official) or Physical Imaging (Alternative). A. Official: Siemens TIA Portal/SIMATIC Manager Use this method for standard project backups. siemens mmc image file download
Not all SD card readers are created equal. Siemens SIMATIC Memory Cards (SMC) are proprietary and often formatted in ways Windows does not natively recognize. While newer SMCs can often be read via standard USB readers using the "User" profile settings, older MMCs required Siemens-specific programming devices (like the PG) to properly access the protected sectors.

Because these are unofficial "bit-for-bit" copies, they are hosted on various community forums and technical sites. Not all SD card readers are created equal
In the realm of industrial automation, the Siemens Micro Memory Card (MMC) is a critical component for the operation of SIMATIC S7-300 and S7-400 Programmable Logic Controllers (PLCs). Unlike standard commercial memory cards, Siemens MMCs utilize a proprietary formatting and security protocol that integrates directly with the PLC's hardware and software ecosystem. The management of these cards—specifically the creation and use of "image files"—is a vital skill for engineers tasked with system backups, disaster recovery, and hardware maintenance.
