Data entry systems with biometric devices for security access control

摘要

A security system incorporating one or more biometric data recognition capabilities in a non-intrusive way to enhance the overall security provided by the system. The biometric recognition may be provided by incorporating one or more cameras in a keypad system wherein the key identifications are altered between uses, and wherein the viewing of the key identifications is sufficiently restricted so that an operator must be adequately aligned with the key identifications when operating the system that reliable biometric data may be automatically obtained during system operation without the need for additional explicit positioning requirements placed upon the user. Other biometric data sensors may also be used if desired. Various embodiments are disclosed.
