Microsoft has just made a correction to a statement they previously made. It seems that Windows Phone 7.5 does indeed lack support for NFC.
Last week, Will Coleman (Developer Evangelist and Product Manager at Microsoft UK) stated that Windows 7.5 does support NFC and that OEM manufacturers can enable it if required.
The statement has now been corrected by a Microsoft spokesperson who stated that Windows Phone 7.5 does not support NFC but Microsoft expects NFC enabled Windows devices to ship within the next year.
Microsoft currently holds around 14 NFC related patents and they have promised to bring support for NFC and more hardware choices to Windows Phone in 2012.
