• Mobile payments will see explosive growth. Mobile in-store payments will grow at a five-year compound annual growth rate (CAGR) of 154%, to $189 billion in 2018 from $1.8 billion in 2013, according to our forecast. While the growth will be explosive, in-store mobile payments will still account for less than 4% of brick-and-mortar transaction value by 2018.
  • A small percentage of people have used mobile payments. In late 2013, just 6% of US adults said they had made a payment in a store by scanning or tapping their smartphone at a payment terminal.

But with Apple's adoption of NFC for the iPhone 6 line, many more people will begin using NFC-based mobile payments. 
  • Apple Pay will succeed and bring mobile in-store payments into the mainstream. Apple has a devoted fan base and the unique ability to change consumer behavior on a large scale. A majority of US tech consumers said they would absolutely use Apple Pay, according to a survey of Business Insider readers. In addition, the company has included a number of features within Apple Pay to address consumer privacy and security concerns. 
  • Other mobile payment apps will compete for consumer attention:
    • The retailer consortium MCX is getting ready to debut mobile wallet app CurrentC, which could reach a huge number of customers who shop at giant retailers like Target and Wal-Mart. MCX merchants will apparently be barred from accepting Apple Pay in stores.
