Noticed an interesting stat hit the wires on Tuesday (Oct. 27) from Juniper Research. Juniper reported “that the increased rollout of contactless payment services using fingerprint scanners will push the number of biometrically authenticated transactions to nearly 5bn by 2019, up from less than 130 million this year.”

Going from 130 million to almost 5 billion in four years is an impressive path—if the numbers are to be believed—but the changes to consumer behavior is potentially even more dramatic. Juniper limited its projection to biometrically authenticated transactions. The reality is that as consumers get comfortable with mobile biometrics, those fingerprint scans will authenticate consumers as they walk into banks, doctor’s offices, gyms and when they open secure apps.

In the same way that fingerprint scans on iOS and Android devices are making consumers comfortable with all manner of biometric authentication, those devices and associated behaviors are also going to open the door to biometric authentication in areas well beyond mobile devices. Indeed, they could open the doors to, well, opening doors.

This is a very non-vicious cycle. Mobile biometric authentication begets more mobile biometric authentications, which beget more consumer comfort with biometrics in untold non-mobile interactions.
