Fanns en app för några år sen till android på playstore som gjorde detta, har också testat och vill minnas den utan större problem läste av allt utom 3 siffrorna på baksidan.
Finns säkert fortfarande liknande appar men kanske inte i officiella butiken....
edit: tror det var denna https://play.google.com/store/apps/details?id=com.github.devn... men devs har cripplat den, läs recensionerna är massa liknande dessa:
"This app used to be a powerfull tool to help demonstrate to people the potential risks involved with contactless cards. Sadly the latest update removed features, severly crippled existing ones to the point where the demonstration is no longer effective, and then asks for money!"
"Dreadful! I used to use this app to demonstrate my RFID shields and I would always scan my own card to show people how easy RFID cards can be read. The paid version only shows the card number when you put in the last 4 to validate. I emailed the developer 3 times explaining this and asked for a refund because the app is useless."
