Nfc device configuration after device power up

A system, comprising:

• a first NFC device configured to emit an electric field from;
• a second NFC device in proximity to the first NFC device and being powered by the electric field emitted thereby, the second NFC device comprising:
• a NFC controller, and
• a secure element configured to send first configuration data and not second configuration data to the NFC controller,
• wherein the first configuration data comprises data to be used by the NFC controller to generate responses to initial polling and anti-collision commands from the first NFC device and wherein the second configuration data comprises data to be used by the NFC controller in processing a command from the first NFC device involving the use of an upper layer protocol.

A method, comprising:

• emitting an electric field from a first near field communications (NFC) device so as to power a second NFC device in proximity thereto;
• and
• receiving first configuration data sent by a secure element of the second NFC device and not second configuration data, at a NFC controller of the second NFC device;
• wherein the first configuration data comprises data to be used by the NFC controller to generate responses to initial polling and anti-collision commands from the first NFC device and wherein the second configuration data comprises data to be used by the NFC controller in processing a command from the first NFC device involving the use of an upper layer protocol.

A method, comprising:

• emitting an electric field from a first near field communications (NFC) device so as to power a second NFC device in proximity thereto;
• and
• receiving first configuration data sent by a secure element of the second NFC device, at a NFC controller of the second NFC device;
• wherein the first configuration data comprises data to be used by the NFC controller to generate a response to lower level protocol commands from the first NFC device, and not data to be used by the NFC controller in processing a higher level protocol command from the first NFC device.
