Forget reply this.
From the packaging, you hardly tell if it is fake.
There is a software online to test the card to see if the card has the capacity as it claimed.
My way of testing is, try load up the card full to see if can store as much data as it can.
Normally fake card will hang around 5% capacity.
i don't have 64gb or higher, only 32gb
fake 32gb is usually 4gb or 8gb cards
i usually transfer 3.8gb of data first, if no data corruption whatsoever, i'll go for 7.5gb, if all good, then it is usually genuine
sometimes, don't have to read the data stored in the card, during transfer itself can see that the data being transferred are already corrupted, by looking at the speed of transfer rate, "the files" got transferred really fast (coz it didn't transfer anything)
