Consumers turn to apps, social media, and mobile-optimized websites to browse through and buy products on their phones—clicking through five screens to pay. One-click checkout has been around since 1997, when Amazon.com introduced it for desktop users.

In October, Apple introduces Apple Pay, which simplifies checkout by using shoppers’ saved information and eases security concerns because it doesn’t store card numbers on Apple phones or servers. So-called digital wallets such as Apple Pay will account for the majority of mobile transactions by 2017, according to Nitin Mangtani, CEO of PredictSpring, a mobile commerce company.
