In physical token-less security screening using biometrics, a person provides biometric data to a security computing device as part of a security screening. The biometric data is used by the security computing device to look up an identifier (such as an airline account identifier or a security status identifier) for the person from a security back end. The identifier is used by the security computing device to obtain electronic pass information (such as an electronic boarding pass or a security screening status indicator) from a third party computing system (such as an airline computing system or a clearinghouse), which may be used to clear the person and/or otherwise facilitate the security screening. In some implementations, these techniques may also be used for physical token-less pass processing (such as boarding pass-less airline processing, confirmation of assigned traveling credentials, or determination of security protocols).
