Retinal Scanners
With the prevalence of hacking incidents, businesses and individuals are seeking ways to make banking and other transactions more secure than inputting a key code or a password. Enter retinal scanning technology that is small and portable enough to fit in a purse or pocket.
The Fraunhofer Institute for Photonic Microsystems in Dresden, German is in the midst of developing a scanner that will “incorporate optical, but not the electronic, components of the device” that will include an eye-safe infrared laser and MEMS scanning mirror.
Building a model that is compact enough to be portable is a function of the prototype that the researchers are developing. Thumb print technology is making its way into smart phones, but because the blood vessels of the retina reflect less light than the surrounding photo-receptors, they can be mapped and easily compared to the retinal patterns of the owner of the device, it is more precise than a thumb scanner or a personal identification code. The blood vessel pattern of the eye is unique to each individual and can be used to verify a person’s identity.
The technology is not ready for the public at this point, but is a work in progress that researchers feel may eventually even integrate into smart phone technology.
