    Sorting out a bit of the above answer of JustinAngel:

    • RFID is not a predecessor technology of NFC
    • RFID covers various frequency bands of Radio Frequency Communication (e.g. HF and UHF)
    • NFC is Near Field Communication and usually covers HF (13.56 MHz)
    • Many standards fall under HF NFC: ISO14443-4, ISO15693, FeliCa, ISO18092, .....
    • NFC Forum is trying to unify things and uses NDEF messages to exchange semantic messages
    • contactless payment on credit cards is based on a contactless smartcard layer.
    • WP8 allows only exchange of NDEF messages
    • WP8 does not allow exchange on the contactless smartcard layer (ISODEP==L4==(T=CL))
    • see the windows proximity api for details or http://developer.nokia.com/Community/Wiki/Use_NFC_tags_with_Windows_Phone_8
    • Android however gives access to this ISODEP layer
    • I don't know what credit card information could be retrieved from an app. There is a secure element involved which handles cryptography and stuff. I don't think detailed information on Mastercard payPass or VISA payWave is freely available
