                                                                                                    FDMM256GBG-XR00 is an industrial microSD 6.1 read-only mode card. The read-only mode is highly effective in a memory device to ensure data security. Read-Only mode provides a tamper-proof data storage solution by making it unalterable and the crucial files remain safe. It provides a security function to prevent the stored data from being stolen, tampered or modified by others. Once the user activates the read-only mode into the memory card, all the stored data enables access for reading only. None can change, delete, or overwrite anything from the stored data. So, users can preserve the authenticity of the essential files in the memory card and prohibit it from the risk of alteration. Write access could only be enabled by authorized user with specific tool and the correct password.
