A method and architecture are provided for obtaining and authenticating a retinal scan using a host device, such as a laptop or hand-held computer, in a manner that is ergonomically sound and is easy to use. A PCMCIA card is used to obtain and authenticate retinal scans. The PCMCIA card includes a removable retinal-scanning eyepiece and an on-board software component for verifying retinal scans. A wired or wireless (e.g., infrared link, Bluetooth, etc.) connection is provided for delivering the retinal scan data from the retinal-scanning eyepiece to the PCMCIA card. The authentication is performed securely on the PCMCIA card and the scan is not retained in the laptop memory.
