Since launching its fingerprint authentication to log into its app, half of B of A's customers have evolved to using it. The Tier 1 bank is now partnering with Samsung to do iris (eye) scanning.
Samsung debuted the iris recognition technology in March during its Unpacked event. The company asserts that the technology is more secure than fingerprint scanning.
