Mobile payments, as a percentage of in-store purchases in the US, crossed the 10% mark. A popular user of mobile payments, Starbucks, was also seeing increasing mobile payment adoption in store locations across the US.

Starbucks' method involved different payment options and barcode scanning. Consumers seemed to find it convenient, with multiple trusted sources.

CEO Howard Schultz said that Americans were lured by the thought of paying with their mobile phones and other digital capabilities. Adam Brotman, chief digital officer, said, "Various digital initiatives have added demonstrable impact to our U.S. business in the third quarter."

Because of this, Starbucks will continue to invest in and push forward with mobile-focused initiatives in mind. This included installing wireless charging mats in select locations.

This could very well be, as 61% consumers in the country believed smartphone payments will eventually take the place of credit card payments for most purchases at stores, according to Harris Interactive. Also, research firm eMarketer expected mobile payment transactions to reach US$20 billion in 2016 and climb to US$58 in 2017.
