HP Eying NFC for Future Phones
According to sources cited by Bloomberg, HP is working on mobile devices that will include near field communications technology to enable mobile payments. Bloomberg's sources said that HP is looking to add mobile payment features to both phones and tablets, and the first products may be available as soon as the end of the year. HP is taking the measure to ensure that its webOS platform and smartphones/tablets remain competitive with rival platforms. A number of NFC-based mobile payment systems are in the works from leading companies such as Google, Samsung, Sprint, Verizon, AT&T, T-Mobile, and others. HP declined to comment on Bloomberg's story.
NFC vs TouchStone Technology
If this is the case I'm curious as to if the Pre3 was delayed to incorporate some new TouchStone/NFC tech. That is most likely wishful thinking as I doubt they'd ever change a product so late to final spec.
I think both of these technologies have mass appeal as I'd love to be able to data with friends by just touching NFC enabled devices together.
