2.the serials and images on the back of the card
3. The super gold plates
4. The plastic (real ones will look different)
5. The sticker on the front (off center and not perfect)
6. Speed testing.

I did a heavy load on the card with 50gb of wedding images and it handled it. Next I did a Black magic speed test and ill post the numbers below. I contacted amazon and they have allowed the refund to be made. I cant risk having a low performance card for weddings especially for the price. If you can please double check your cards by verifying it through Sandisk services. All you have to do is email them with the serials on the card. Super easy and they respond within a day. I gave it two stars because amazon service is amazing. I also have some images of a fake and a real card. Hope this helps
Cards with 32GB or less are SDHC and should work with most devices released in the last few years. SDXC will cover cards with higher capacities, such as this card in 64GB. This is an important consideration to Linux users since SDXC uses exFAT which may not work with your OS. If you have an up-to-date Windows installation or a recent Mac release you will be fine without third party software, though a firmware update may be necessary for your card reader if it's pre-'09.
You will not achieve UHF speeds on a USB 2.0 bus - you will see a maximum 20-30MB/S depending on file size and other factors. On many host devices the speed gains are negligible during operation because of fast internal memory buffers - I can burst (9/s) an average of 15 shots in RAW+jpeg on my DSLR with a class 6 card, or 18 with this - so probably not worth the premium price for that gain alone. Video there is no difference since the class 6 can float the 20mbps required for 1080i on my camera. In other words, if you can get the extreme pro in 64GB for the same price as the extreme in 128GB, your money is probably better spent on the extreme, if not on a non-UHF card, which is to say class 6 or 10.
It may be noteworthy that this card is waterproof and x-ray proof, but does not specify that it is magnet proof as other brands' documentation does. That said, Sandisk has some of the most robust built-in error checking features in the 'biz and other brands don't really compete in quality if you do some research.
My advice is to make sure you can use the extra speed you're paying for - if you don't have a USB 3.0 card reader, a host device with USB 3.0 PC connection, or a built-in card reader on a laptop that's either newer or has a recent firmware update, you may be wasting a fair sum of money here. Also make sure your device says SDXC if you do go above 32GB. Many devices' documentation will explicitly say that it works up to 32GB. It'll just try to format the card over and over if you feed it an SDXC.
Hopefully some info here was helpful! Happy hunting
I have learned the error of my thinking. If you are a hobbyist photographer, shooting landscapes or family/friends you may not see a need for this disk depending on what you shoot. If you are a professional wedding photographer or a sports photographer; or any kind of photographer where you NEED to capture that one special shot then you NEED this card.
Here's my story: I had run out of space on my Sandisk 32GB while photographing the bride getting to the church. I put in a standard Kingston 16gb SDHC card to shoot the ceremony with. BIG MISTAKE!! I was preparing for the bridesmaids to march down the aisle so I had my camera set to take a quick succession of pictures (in case one had her eyes closed). My camera took so long to cycle that I missed completely the next bridesmaid. It turns out that the Kingston writes at around 4mb/s compared to the Sandisk at 95mb/s. That is a huge difference. Needless to say that I captured the bride getting fed cake, but missed her smearing it on his face. If you don't think that speed matters, wait until you have to tell the bride that you missed an important shot because the disk in your camera can't keep up with your camera. :(
I actually came to this site today to purchase another one; and while I was here decided to put in my thoughts on this disk. Don't be "that photographer" who is known for missing important shots like I did.
