The growth in these areas of mobile payments is set to increase in line with the number of smartphone sales around the world.
According to the latest research from Gartner, published on 14 February 2012, total smartphone sales in 2011 reached 472 million units and accounted for 31 per cent of all mobile devices sales. This was an increase of almost 60% on 2010.
Total mobile phone sales in 2011 reached 1.8 billion units, an 11.1 per cent increase from 2010. “Expectations for 2012 are for the overall market to grow by about 7 per cent, while smartphone growth is expected to slow to around 39 per cent,” said Annette Zimmermann, principal research analyst at Gartner.

In an update report in 2013, Gartner moderated its growth expectation for NFC somewhat. It was estimated that NFC payments only accounted for 2 percent of transaction values in 2013. Sandy Shen, research director at Gartner, noted that some high profile services such as Google Wallet were struggling to gain traction. It was expected that NFC payment would account for 5 percent of the total transaction value in 2017. although growth is expected to increase somewhat from 2016 when the penetration of NFC mobile phones and contactless readers increases.
