CardTest

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.

Impressed! Now I really know how unsafe it is to have contactless credit cards! Be sure to enable SMS alerts from your bank if you got one! Better safe than sorry

Listen. 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.

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.
