According to reports from Sandisk, one third of all memory cards on the market are counterfeit.
Many buyers of counterfeit products find that branded SanDisk cards are actually re-branded inferior quality cards or cards of smaller capacity.
All genuine SanDisk memory cards should have a serial number and a manufacturing country's identity. You can not determine the authenticity of a Sandisk card from an internet stock photo.
You cannot determine the actual memory capacity of a counterfeit memory card by simply viewing the capacity displayed by your computer, phone or camera. Counterfeiters fraudulently overwrite the cards internal memory with a false capacity. It must be checked with a test program.
To check if your Micro SD drive has the capacity and speed stated, "H2testw" is a simple tool that is distributed for free, does not require installation and offers a very simple, easy-to-use interface. The program can be used by anyone who wants to know how their actual product compares to others, the real capacity and the amount of errors that can be detected on their device.
The Secure Digital standard is maintained by the SD Association (SDA). The Secure Digital format includes four card families; the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity (SDXC), and the SDIO. The cards are available in three form factors; original, mini size, and micro size.
It is not unusual to find counterfeit and generic cards with memory substantially below what is printed on the card. If you don't check your purchase, you may lose content or damage your equipment.
SanDisk offers responsive and excellent support through their online customer service.
There is no way to determine authenticity from a internet stock photo in a listing.
To ensure you are receiving an authentic SanDisk product, always buy from an authorized SanDiak retailer.
All genuine SanDisk memory cards should have a serial number and a manufacturing country's identity. This is usually not on fake cards. The bar code may also indicate a different product than the packaged product.
