Methods and apparatus for improving re-activation of a nfc-f based remote nfc device

A computer program product for inductive communications, comprising:

• a non-transitory computer-readable medium comprising:
• code for causing a computer to:
• determine, by a polling near field communication (NFC) device, that a remote NFC device that is supported by an NFC-F access technology was previously deactivated;
• and
• transmit a sense request message to enable the remote NFC device to receive an attribute request message as part of a device activation procedure.

A polling near field communication (NFC) device apparatus for inductive communications, comprising:

• a transceiver;
• a memory;
• a processor coupled to the memory;
• and
• an NFC-F device activation module coupled to at least one of the memory or the processor and configured to:
• determine, that a remote NFC device that is supported by an NFC-F access technology was previously deactivated;
• and
• transmit a sense request message to enable the remote NFC device to receive an attribute request message as part of a device activation procedure.

A method of inductive communications, comprising:

• setting, by a polling near field communication (NFC) device, a sleep flag to indicate that a deselected remote NFC device that is supported by an NFC-F access technology is in a sleep sub-state;
• determining that the remote NFC device is to be activated as a type 3 tag as part of a device activation procedure;
• and
• resetting the sleep flag to indicate that the remote NFC device is no longer in the sleep sub-state based on the determination.
