How to recognise a fake memory card ?

As fake memory cards do exist today in the marketplace. and we use lots of memory cards in our Digital Camera, Mobile phones,etc...

Determining a Fake Memory Card
Unfortunately there is no software which will test the card, and ensure that it's genuine. You must manually scrutinise your card, (both visually and by testing it's performance), to get some idea of it's genuinity.

Build Quality helps to determine fake memory cards

First thing to look for is poorly printed labels and material; most fake cards have slight differences from the real deal. Most manufacturers have a page where you can download high resolution pictures of their cards. Below is a list of manufacturer image page links:

• Sandisk
• Sony
• Olympus
