The card does not have just a static chip, so when it is touched information is passed through, encrypted, and sent to the bank to be decrypted and authenticated which creates the transaction. This means it is not as simple as copying the data on the card, however you can use Google Wallet. This advice will be short lived if you device does not support host card emulation and is not KitKat

Should I be able to scan a Chase debit card with blink? What are some other things I can scan to test it?
buy some thing at McDonalds
when i put my phone near my subway card, it made a beating sound.
I installed NFC Taginfo and scanned my Chase Debit card (Chicago Bears card with Blink). Once that showed up, I ordered writable tags. Should be here any day.

Mine won't read my debit card nor my gf's debit card. I'm trying to think of some other things that I could read to test it.

US Passport?
Flashed back to stock 4.0.2 and it reads my Chase card now. IDK if it was AOKP or Franco's kernel that screwed up my NFC.

I wanted to add files larger than 4GB on my card so I formatted the card to exFat through my PC. Then it reads 896KB... So i format it again using my phone and now i see 59.4GB but its of the "generic hierarchical" file system, and I still can't add files larger than 4GB. Is there anything special I need to do to achieve my goal?

Try for formatting the tool SD Formatter. SDXH microsd cards are having specifications, which are not supported on windows format tool. I a similar problem with formatting, but it come out that my san disk sdxh microsd was defect, so I just got a new one from amazon.

No, your card is not corrupted, it most likely is a fraud.
These fake cards are made in China and sold as if they were 64 GB. The print on it says it is 64 GB, even if you put them in your computer, the computer states that they are that large. Once you start copying data onto them, the copying fails.
I bought one on eBay from a chinese seller. I´m glad I was refunded by PayPal.
There are many fraudulent sellers who selll these fake cards, so beware! These sellers often have a low feedback and disappear from eBay once people start claiming.
This one is a fake as well, I guess. It´s always the same pattern: they sell very cheap cards and these are all fake.:

How can that be a fake? He doesn't say anywhere that he's selling a SANDISK 64GB card.
Because the card is probo a 4gb card formatted to look like a 64gb card. I've been stung in the past by these thieves and now won't use ebay for any memory. Amazon is the best for memory now with their excellent return policy if there are any problems. My first 64gb SanDisk card was defective and they exchanged it with zero trouble.
The best thing to do with memory cards is to test them as soon as you get them. Fill the card to the brim and check the files play. This way you can prove the card isn't a fake.

Hey
Is there any way to clone a Mifare Classic card via the NFC chip on the Samsung Galaxy Note II GT-N7105? I tried many apps for reading it and no succes... Thanks in advance!
No, there are no apps for that. Mifare Classic cards have secret key components that can not be copied.
You may only hack a mifare classic card with expensive equipment that can analyze the radio waves of the communication between the card and the reader station. And that is not something that can be accomplished by todays phones. Visit the "CARTES" conference if you want to see a such "hacking" equipment.

I recently purchased this sd card from him and it was counterfeit: http://www.ebay.com/itm/310853963580
He sold me a class 4 4gb sd card instead of a class 10 64gb sd card. Here is the email I sent him that contains proof and things to look out for if you ever suspect your sd card is a counterfeit:
I have reason to believe the Samsung 64gb micro sd card that you sold me is counterfeit.
I first had a hunch this item was counterfeit when I copied 45gb of data to the card two separate times just to have it all erased/corrupted immediately after putting it in my phone.
After this happened, I decided to download an Android app called sd insight to see if the card was fake or not. These are the results I received from running the app: http://pastebin.com/RfG0JREq
As you can see in that log file, the manufacturer, product name, revision number, etc are all null. This led me to believe that the card you sold me was certainly counterfeit. If this was a legitimate card the entries would have reported things such as SAMSUNG and MB-MGCGB/AM. (The supposed make and model of this sd card) Additionally, there would be at least 1 revision to this card to counter the data corruption issues that was occurring to S3 and S4 smart phones in 2013 since it was manufactured (supposedly) in January of 2014.
In order to be sure for certain before I contacted you with this claim, I used a program called H2testw. H2testw is a program that writes data files to your sd card and reads them off until every sector has been tested. If corruption occurs you have an sd card error. Additionally, you can see the actual size of the sd card and many other cool things. Here is the log file that the program returned to me: http://pastebin.com/X8e0R6TM
As you can see, this card is actually only 3.5GB instead of 62.4 like reported by Windows Explorer. This leads me to believe this card has been hacked to report the incorrect capacity size. 58.8GB of data was lost because it was written to sectors which actually don't exist... This is proven by the hex address given by the location of the first error.
As you can see, it expects to encounter 0x00000000c65db000 but instead encounters 0x0000000000000000 when trying to copy data to that specific location. This is because that location doesn't exist....
Finally, you can see that the writing speed is only 3.8mb/s instead of 7mb/s and the reading speed is only 6.64mb/s instead of 24mb/s. This is another clear sign of a fraudulent item.
You sold me a class 4 3.5GB sd card in disguise of a class 10 64gb sd card. I would like for this item to be replaced with a legitimate Samsung 64gb class 10 micro sd card at no extra expense to me. This includes reimbursing my return shipping fees if you desire the item to be returned to you before continuing.

Additionally, here are some pictures I took for the claim: http://imgur.com/a/jJrcJ
Also, here are the tools that I used to detect this counterfeit:

I bought a counterfeit 32gb sd card once on ebay... made a report with paypal. Sent my emails with the seller to paypal...they tried emailing the seller also. No response. I received my money back in a few days. No sweat. I never buy anything without paypal.
I have found that buying sdcards on eBay is a risky endeavor. Cavieat emptor....let the buyer beware

This. If it looks to good to be true, it is. You will never see a real Samsung 64gb card for $25.
