Hey, I was doing a bit of research and some people were talking about having an android app that can scan the NFC chip of a visa or mastercard and get you its code. Does anyone have the apk? And i don't need the EC/Credit card info app that was designed by a german, i have it and it only reads german cards. Thank you for your time.

http://www.triangle.io/ has an API if you wanted to write your own app

https://play.google.com/store/apps/detai...m.noSquare also looks interesting

http://sourceforge.net/projects/nfcproxy/ also looks quite interesting.

These are all links found in a search that lasted about 20 seconds on google btw.

well you are one talented individual. I'm not always this dumb, but i seriously searched for 2 days now. Is there any link between the number on the back, exp date, and the card number itself? Like an algorithm or something? or just assigned by the bank. Got a challenge i need to pull off.

Well, the expiry date is random. well, not random, but decided on the terms of the bank. This is usually between 2-4 years in my personal experience but could be greater or less theoretically.

as for the cvv... yes its related to the number on the front of the card, but no you cant directly generate it based on the card details alone. there is other considerations.
