Within the next decade, smart-device swiping will have gained mainstream acceptance as a method of payment and could largely replace cash and credit cards for most online and in-store purchases by smartphone and tablet owners, according to a new survey of technology experts and stakeholders.
Many of the people surveyed by Elon University’s Imagining the Internet Center and the Pew Research Center’s Internet & American Life Project said that the security, convenience and other benefits of “mobile wallet” systems will lead to widespread adoption of these technologies for everyday purchases by 2020.

Others - including some who are generally positive about the future of mobile payments - expect this process to unfold relatively slowly due to a combination of privacy fears, a desire for anonymous payments, demographic inertia, a lack of infrastructure to support widespread adoption, and resistance from those with a financial stake in the existing payment structure.
