Is there any tool provided by SanDisk officially to check the authenticity of its memory cards.

:smiley:  Hi Amritmgr,

Dear member of SanDisk Community, welcome.

Mmm… No, or I do not know, so that it occurs to me, the following:

1- You can consult their doubts with: SanDisk Technical Support: http://www.sandisk.com/about-sandisk/contact-us/

2- You can, if you like, do experiment with: http://forums.sandisk.com/t5/Mobile-memory-professional-cards/Fake-micro-SD-cards/m-p/330309#M3490

Enjoy, and then you tell us, what happened, please.

Regards, Alfred.                                                             (Google translated)
