FYI: near-field communication API FPWD

Just an FYI, there's a First Public Working Draft of a Web NFC API, so that web pages can write to and read from NFC tags and peers.

While I expect most of the serious privacy impacts for this kind of technology are going to be implementation-specific, are there also privacy considerations that should be part of the specification? Does someone want to lead a privacy review of this document?

I've often heard NFC described as a technology where privacy is one of the main features: because of its shorter range, data tends to be communicated by clear and intentional physical motion rather than some invisible process. That being said, the ability for an API to power on an antenna and send data off of the device are potentially privacy-sensitive.
