CardTest

Out of curiousity I created this demo application to see how much data NFC enabled credit cards give up to a random reader. It turns out they give you pretty much everything you see on the front of the card.Despite some news reports proclaiming NFC credit cards can be read by passing strangers, in my experience the card has to be in close contact with the back of the phone to get a good read.Out of paranoia, this app censors credit card info and the content of "track 2 equivalent data" as I would hate to release something that could be used for evil.This app has only been tested on UK cards, with a Galaxy Nexus so may not work on other credit cards. The app does not save or transmit any of the read data, but you use it at your own risk.

Use to work fine on my note 2 and read all cards thrown at it but no longer works on s6 edge+ reads some I'd cards but bank cards have stopped reading. Could of course be a security thing on the cards but most probably the s6 isn't compatible in the same way.

Ummmm hello you are voluntarily proving your credit card info to the developer and his coverts. Don't be surprised to see unexplained transactions on your cards.

Just sits there saying waiting for nfc and does nothing when I hold something near it Even with everything turned on

It worked a about twice, but very often crashes on my phone when attempting to scan. Running OnePlus One

Does not work, only "waiting..." . I noticed the last update was 2012; this would probably explain why newer phones are not working. The website for this app is a total dud as well. Don't bother with this app; sorry dev. but you did not stay with the times.

Doesn't work on newer phones. Tested on the HTC one M8 and Samsung GS4 no go. Same cards work on HTC One X

Just installed on Nexus 7 2013 with Marshmallow. Doesn't seem to work on MBNA card but does on HSBC debit card.

I know this app was written and tested in the UK with a specific mobile phone. Just thought I'd report my test.

Samsung S5 - Works well, anyone having issues with this app, is not using it properly.

Works very well on my Nexus7 and Nexus4 with one of my UK credit cards. A little scary just how much is on the card and how easy it is to read!

Not working on note 4. In reference to the person saying its sending the credit card information out, that false. check the permissions granted to this app. internet is not one of them so it can't send anything out, assuming you are NOT rooted

Good way to test if you're cards are faulty. I'd say 75% of bad reviewers don't realise the card needs to have contact less capabilities

This app reads cards with rfid compatibility. You know.... cards that you can put on your phone and wave in front of the reader at the register to pay.

Works with capital one CC, but not a Halifax bank contactless card. It's good to see though how much information the card gives to the reader in stores/shops

Jar. R. Apr 7, 2014     

It would be way better for there to be like a version that can fully scan cards so developpers can work around card skimmers and soo

Three EMV cards and nothing. Only registered one but couldn't read it.

Doesn't seem to work with Australian paypass cards. I can read my Monash library card with a different app, however this one does not work. SIII.

Worked on my Galaxy 5. Interesting the personal info stored. One card had almost everything readable.

Dan. J. Jun 5, 2013     

Does beep when Card is passing rear of phone but then App crashes with error message that the App has to close! Doesn't return any Card credentials.

Tried it on my Nexus 7 and it works with most of the cards I tried. It hides parts of credit card numbers it finds, which is good!

Soh. T. Jan 16, 2015     

Reads and tells surprisingly lot of info. Tells us how unsecure our cards are.

Mik. V. Jul 4, 2014     

Some time after using this app my card got blocked as there was an attempt to pay with my card in US (I'm from UK)... I never gave this card's details anywhere and never payed with it online...

Mat. D. Apr 24, 2013     

Works exactly as advertised. Very interesting to see what info gets out of the CC. Awareness!

Makes Noise When I Hold My Wells Fargo cars up to it then nothing

Tried a few times with my HSBC card and every time it crashes

Doesn't work, probably isn't smart to scan a working card anyways if it did.

Luk. D. B. Oct 17, 2014     

I tried some cards, most of them are secured so try and find a way to get passed security issues.

Getting "unfortunately nfc card reader has stopped" after presenting a card. Report not sent, I'm sorry but I'm not giving this app permission to transmit anything. Galaxy S4 i9505.
