Biometric authentication, a technology that uses unique physical or behavioural traits for identity verification, has gained popularity in recent years. However, not all consumers have embraced biometrics’ potential, and convincing those who are not interested in adopting the technology can be a challenging task. One effective approach to persuading uninterested consumers to use biometrics is by offering rewards or discounts. The study found that 72% of uninterested consumers would be willing to use biometric methods if merchants provided such incentives. Additionally, one-third of consumers who have used biometric authentication methods also expressed their willingness to use it if rewards or discounts were offered. While offering incentives can be effective, it is important to consider the associated costs. Therefore, alternative strategies should also be explored. One such strategy is to increase the acceptance of biometric authentication among merchants.
