Title: SD card manufacturer ID Post by: acinonix14 on September 01, 2014, 06:30:12 06:30 Hi,
I would like to ask how can I found a list with available manufacturer ID on SD card to check if the card is fake or not. I am read the SD card registers, and more specific the CID register and it returns 0x27. The card is SD-card 2GB Verbatim. CID Register Manufacturer ID : 0x27 OEM ID : PH Product name : SD02G Product revision : 3.0 Product serial no :011E8DAE Manufact. date : 12 / 2011 Thanks, Title: Re: SD card manufacturer ID Post by: CocaCola on September 01, 2014, 09:58:31 09:58 What makes you think the 'fakes' or 'clones' are not going to have fake or cloned manufacture info as well nowadays just like many of the fakes have had exaggerated fake capacity data written to them over the years?
There is no official public list only the proprietary and 'secret' one held by the SD group, but here is one someone assembled one based on samples, but take it with a grain of salt, lots of rebranding and repackaging in the memory industry... https://wiki.linaro.org/WorkingGroups/KernelArchived/Projects/FlashCardSurvey?action=show&redirect=WorkingGroups%2FKernel%2FProjects%2FFlashCardSurvey Title: Re: SD card manufacturer ID Post by: pickit2 on September 01, 2014, 02:15:43 14:15 http://www.bunniestudios.com/blog/?page_id=1022
is another interesting read. I seen at a local phone shop, a box of microSD cards, that was being repackaged, when the shop was not busy.

From the list, I see it is not easy to check the originality of card.
