Congrats to Touchtech! Acquisitions are always exciting :) I'm wondering what this means for multi-factor authentication with regards to payments. Why bio-metrics instead of a physical security key and U2F? Convenience? Customer reach?

What might this mean for future legal precedents regarding biometrics?
