As discussed herein, these odorants may be collectively referred to as a “smellprint.” Biometric security system 2202 may include a biometric sensor 2204 which may be configured with an electronic sensor, a chemical sensor, and/or an electronic or chemical sensor configured as an array of chemical sensors, wherein each chemical sensor may detect a specific odorants, or smell. In another embodiment, biometric sensor 2204 may be configured as a gas chromatograph, spectrometer, conductivity sensor, piezoelectric sensor and/or other hardware and/or software that facilitates the capture of biometric data from the person such as, for example, scanning, detecting or otherwise sensing a smellprint of cardmember.”
