According to the international poll by Unisys, 67 per cent of consumers would trust fingerprint scanning to verify their ID with banks, government agencies and other bodies.
Some 44 per cent would accept facial scans, while another 38 per cent would be prepared to scan the blood vessels in their hand.
Customers in the UK, Australia and Malaysia were the most accepting of biometric verification overall, the company said.
Meanwhile, a parallel survey indicates that growing concerns over ID theft and fraud could be behind the rising support for biometrics. Card fraud was rated in the top two security concerns by consumers in 11 out of 13 countries, while ID theft rated first or second in another ten.
However, Terry Hartmann of Unisys said that while consumer support for biometrics is growing worldwide, many companies are "yet to embrace" the technology.
"Cybercriminals can exploit what could be weaker oversight and customer service at companies and banks due to market upheaval," he warned.
Unisys was formed in 1986.
