NFC offers three different operating modes:
Reader Writer Mode is already available in Android since the first Gingerbread release in December 2010. Card Emulation Mode, which is actually required for Google Wallet, is not yet available for public. Peer-2-Peer Mode as defined in ISO 18092 is now finding its way into Android devices, also known as “Android Beam”.

- Reader/writer mode, allowing the NFC device to read and/or write passive NFC tags and stickers.
- P2P mode, allowing the NFC device to exchange data with other NFC peers; this operation mode is used by Android Beam.
- Card emulation mode, allowing the NFC device itself to act as an NFC card. The emulated NFC card can then be accessed by an external NFC reader, such as an NFC point-of-sale terminal.
