About this app

If you’re a digital camera or gadget enthusiast you are probably aware that it can be difficult to know if your SD card is actually authentic. Counterfeit memory cards have now spread throughout the marketplace. Packaging on the cards can make it difficult to distinguish a fake SD card from the real thing.

SD Insight is a free, fast and easy to use application that you use on your cell phone. Within seconds the application reads the technical details from your SD card and displays the information in an easy to understand format.

***COMPATIBILITY NOTICE: It has come to our attention that SD Insight is not compatible with some Android 7.0+ handsets. In addition, some Android tablets use USB SD card readers which are also not compatible with SD Insight.

In the world of SD cards, the brand visible on the card is often a vendor that labels other people’s chips with it’s own branding. For example, a major SD card brand such as Kingston will place their brand on SD cards that are actually made by others such as Toshiba or SanDisk. SD Insight displays the actual manufacturer not the vendor’s brand.

It is not possible for SD Insight to be aware of every possible SD card manufacturer – as such, it is possible that the manufacturer will be displayed as “Unknown”. A reading of “Uknown” does not necessarily mean that the SD card is fake, but rather that the card is made by a brand or manufacturer that is not currently identified in the SD Insight app. We are continuing working to improve the database of manufacturers in the SD Insight app, and announce our software release updates to our Twitter account at @sd_insight.

Using SD Insight, you can also view technical details about the internal eMMC and SDIO devices in your cell phone.

Interesting app. I bought 32 GB SD Card. Inserted it and clicked on this app. Instantly, the manufacturers name appeared INVALID (some will show UNKNOWN). though it showed the SD card size. Even the seller was surprised. From the same maker, I inserted another and it was genuine (it showed the manufacturers name). Thanks much., P.S,, It can be updated or upgraded to work in higher Android versions also.

Lost a lot of time because there is no clear instructions how to decide if a SD card is genuine or fake. The card I bought was labeled Kingston but SD inside showed another brand. The FAQ explained that it is normal for some manufacturers to use other brand names with their labels. The only suggestions what's fake could be I found after watching the attached video and saw that on a screen it showed the word invalid. If this is the case they would have saved me a lot of time if they clearly said at the beginning of the instructions that fake cards are marked as invalid
