Visa’s Biometric Paymentsstudy, which surveyed 14,000 people across Europe, revealed that 73 percent of people think biometric security checks on a payments device is a secure authentication, with fingerprint the preference for 81% of consumers, followed by iris scanning. The use of selfies and voice recognition were less popular with only 15% and 12% respectively saying they would use these methods to authenticate payments.

According to the survey, biometric authentication is valued both in face-to-face and online transactions. Some 48 percent of respondents want to use it for payments on public transport, 47 percent when paying at a bar or restaurant, 40 percent when shopping online, and 39 percent when downloading content.
