content: So basically I'm learning about RFID and magstripe hacking, as well as hacking Bluetooth with Wireshark. It's all really easy too.. You can buy a magstripe reader/writer for like 20$ on Amazon. You can buy an RFID reader/writer for like 25$. You can even make a skimmer that can snag data from an RFID implanted card from up to 3' away. What's the point of this though? I mean aside from skimming credit cards?  Any other practical use for editing magstripe data? Also, is the data sent from the RFID on a CC encrypted?
