A new survey by Juniper Research has found that more than 40 percent of iOS users in the U.S. consider themselves unlikely to use facial recognition as a payment security technology, according to a press release.

Contactless payment users consider fingerprint sensors and voice recognition more appealing authentication methods, with 74 percent and 62 percent respectively saying they are likely to use these technologies.

The survey also asked 500 U.S. and 500 U.K. smartphone users about mobile banking and contactless payments and yielded these results:

• Overall the number of contactless payment users grew by only 2 percent year-over-year in the U.S., with most deployments coming from smartphone OEMs.
• Contactless user numbers in the card-first U.K. grew by 12 percent.

While mobile contactless payments use will grow in both markets, existing users will fuel most of that growth, Juniper found:

• In the U.S., 73 percent of "Pay" users expect to increase their use, but only 39 percent of nonusers expect to start using mobile contactless payments.
• In the U.K. only 26 percent of nonusers reporting expect to start using these services.

Of nonusers of contactless payments, 32 percent have concerns about the security of the transactions, a far higher proportion than contactless users, at 14 percent, Juniper said.

Mobile banking bears out a similar pattern; 30 percent of nonusers are concerned about the security of transactions, compared with 10 percent of users.

“Transaction security is a key barrier for mobile financial services adoption,” research author James Moar said in the release. "Addressing these concerns will bring many consumers to the point where they will consider using such services."
