Mobile and online purchases worldwide will soar to 125 billion transactions a year by 2018, rising by 60 percent over 2015's total, according to Juniper Research.
The company said that the growth will be driven by several mobile device-related factors, including the rise in "commuter commerce" in which people make purchases from their smartphones or tablets when on the go.
Greater WiFi and 4G connectivity on public transport will also help to accelerate this concept of buying while travelling.
Juniper also noted that as people continue to move away from physical formats, such as CDs and DVD, to more digital and streamed services the number of online and mobile transactions will increase.
However, Dr Windsor Holden, author of Juniper's Buying Into Online Shopping whitepaper warned that recent high-profile data breaches have left consumers uneasy about conducting online transactions, requiring retailers and service providers to find ways to build trust with customers.
"At worst, data breaches can lead to significant customer churn, together with possible remuneration requirements. Consumers need to be reassured that their vital information is not being compromised or shared," he wrote.
The research also identified that retailers will need to deliver consistency with their brand, messages and shopping experience across all e-commerce offerings.
Furthermore, Juniper suggested that retailers must find ways to scale up the resources that support their online presence to deal with peak periods such as Black Friday and Christmas.
Related research from the firm also found the growing e-commerce sector in China will see the number of digital transactions surge ahead of those in the US, thanks to e-retail firms like Alibaba attracting more than 330 million customers in 2014.
China saw digital transactions hit a value of nearly $450bn last year, sailing past the US total of $296bn. This makes China the world's largest single e-commerce market, ahead of Japan, the US, the UK and France, and an attractive prospect for online retailers to target.
Technology will play an important part in the future of retail, whether by influencing physical or digital transactions. Startup The Dandy Lab has used IoT technology to fuse online and high-street retail and launch a store that hints at the future of shopping.
