30m NFC-enabled phones were sold in 2011

"According to a new research report by Berg Insight, global sales of handsets featuring Near Field Communication (NFC) increased ten-fold in 2011 to 30 million units. Growing at a compound annual growth rate (CAGR) of 87.8 percent, shipments are forecasted to reach 700 million units in 2016. The global rise in smartphone adoption is also driving higher attach rates for other wireless connectivity technologies in handsets including GPS, Bluetooth and WLAN. These connectivity technologies are already a standard feature on high-end smartphones and most medium- and low-end models. Declining costs will also enable broader integration in the featurephone segment that is rapidly gaining smartphone-like functionality. The attach rate for GPS among GSM/WCDMA/LTE handsets reached 31 percent in 2011 and grew to 38 percent for all air interface standards. Shipments of WLAN-enabled handsets have more or less doubled annually in the past four years and the attach rate increased to 33 percent in 2011."
