A managed service for a near field transaction that may include a server to register a wireless device with the managed service, provide authentication information to the wireless device for use in establishing an identity of the wireless device. The server may provide authorization information to a register on behalf of the wireless device to establish the identity to the register, where the identity, when valid, allows the wireless device to participate in the near field transaction via a secure near field communication session with the register, receive transaction information from the register or the wireless device, and store the transaction information with a transaction identifier, where the transaction identifier is used to recall the transaction information on behalf of the register or the wireless device.
