A new study from Juniper Research has found that the increased rollout of contactless payment services using fingerprint scanners will push the number of biometrically authenticated transactions to nearly 5 billion by 2019, up from less than 130 million this year.
The research observed that at present, only two services, Apple Pay and Samsung, used fingerprint scanners for authentication, with availability currently limited to the U.S. and U.K. for the former, and the U.S. and South Korea for the latter.
