摘要

A method performed by a biometric collection device, including: conveying a waiting signal to a user of the biometric collection device in response to the biometric collection device being waiting for at least one finger to be placed on the biometric collection device; capturing a flat fingerprint or a rolled finger print of the finger; and conveying a result signal to the user in response to the biometric collection device succeeding in or failing in capturing the flat fingerprint or the rolled finger print of the finger, wherein the waiting signal differs from the result signal in at least a length of lighting or a color.

At step 240, the fingerprint scanner 10 can determine if other fingerprint images should be captured. Continuing the example begun above, once the visual display 14 generates a third signal, the fingerprint scanner 10 can standby to capture the other nine fingerprints of a person. The fingerprint scanner 10 can once again generate the first signal to indicate that a different finger will be scanned next. For instance, the visual display 14 can next pulse the index finger light 40 of the right hand in red to indicate that the fingerprint scanner 10 is ready to capture the right index finger. If the user of the fingerprint scanner 10 would like to generate an image of the right index finger, steps 210-230 can be repeated for the right index finger and the progress of capturing the fingerprint of the right index finger can be indicated with the right index finger light 40. In that way, steps 210-230 can be repeated for each of the remaining fingers on both hands until fingerprint images for all of the fingers on both hands are captured. At that time, the finger indicator 28 can constantly or solidly illuminate ten green lights for lights 34-52. Alternatively, the user can choose to selectively capture only a portion of a person's fingerprints by using the skip finger function 58 of the user inputs 16. The method 200 then ends.
