Can HTML5 access NFC chips on mobile phones

I'm not too familiar with HTML5 so does anyone know if HTML5 will be able to access NFC chips built into mobile devices? Or, can someone suggest another way to do this using some other method? My goal is to produce a cross platform HTML5 web app that can access NFC functionality on NFC equipped phones. I have looked into mobile frameworks like PhoneGap but although they have NFC on their roadmap, they do not have any timelines nor implementation details to offer.

Thanks.
