just wanna gather some experts comments on the future of NFC.
With the implementation and support for NFC in Google’s Android 2.3 platform, I think that NFC has a very bright future. See link for more information about NFC in Android.
Google's Android 2.3 (aka: Gingerbread) has been out for awhile, the last point release "2.3.3" was released on 24 February 2011.
Android's source is available here: http://android.git.kernel.org/
Or you'll have to wait for your phone/provider to provide an update if they choose too.
For cell phones with NFC, read http://www.digikey.com/techzone/archive.page?site=us&lang=en&zone=wireless
And more merchants are supporting Google wallet as well.
The future of NFC, I believe, will be in POS and access controll environments. The organization I work for is currently investigating the usage of an NFC Boot Loader for RFID readers. NFC conforms the ISO 14443 standards running at 13.56MHZ. this means that an android device with NFC could be used in existing residential and corporate environment. combind NFC with hardware released by organizations such as Schlage tha allow you to controll your home with an app on your android device and the posibilities are endless.
I see that Windows Phone 7 is likely getting support in the near future as well.
Automotive: NXP Semi actually has the NCF2970 single-chip solution for multifunction car keys. The chip enables car makers to offer a new driving experience with keys that connect to external NFC-compliant devices, such a smartphones, tablets, and laptops.
It allows data exchange with NFC-compliant devices via a standardized 13.56-MHz wireless link.
It has a 125-kHz front-end for the immobilizer and passive keyless entry/go systems, and works with an external UHF transmitter (315 to 928 MHz) for both remote keyless entry and passive keyless entry/go systems.
Also check out the Melexis NFC transceiver chip for cars, http://www2.electronicproducts.com/NFC_transceiver_is_qualified_for_cars-article-icacn02_feb2012-html.aspx
STMicroelectronics also has the ST21NFCA single chip designed for supporting 13.56 MHz contactless communication, including NFC functions in the three operating modes: card emulation, reader/writer and peer-to-peer communication. This chip came out in 2008, but is not avaliable in disribution - for some reason.
Another chip worth looking at is the Texas Instruments TRF7970A integrated 13.56-MHz transceiver. Digikey has devices in stock and a evaluation board available.
It meets NFCIP-1 (ISO/IEC 18092) and NFCIP-2 (ISO/IEC 21481) standards and comes in a 32-Pin QFN 5 x 5 mm package.
