A method of verifying identity which includes recording coordinates of a reference signature which include two dimensional space coordinates x and y exerted by a writer's writing instrument on a recording medium. The method measures and records an indicium, which identifies a reference biometric within the reference signature having a selected characteristic. Next the reference biometric and the indicium are placed on a portable, readable substrate. The coordinates of an unknown signature which include two dimensional space coordinates x and y covered by a writer's writing instrument are also recorded. The method further includes reading and storing the indicium and the reference biometric in memory and using the indicium to locate an extracted biometric within the unknown signature. The extracted biometric is compared to the reference biometric to determine if they match within predetermined threshold criteria. The reading and storing or the reference biometric and indicium, the recording of the unknown signature, the location of the extracted biometric, and the comparison of the reference and extracted biometrics are all performed on-site. <IMAGE>
