That's RFID. Yeah, you can read that with a $5 reader off ebay.
I'm talking about Visa PayWave/Mastercard PayPass - both work through NFC and won't surrender any data to a normal reader, you need an authorized terminal that can give an authorization key valid for a given time. There were some attacks against it, but you can't just swipe a card through a wallet, it's extremely time sensitive and requires access to a valid terminal.
