OK, so what kind of data does our software capture? The answer to this question differs depending on where the driver's license is issued and when it was issuesd. Some states in the U.S. simply record what is printed on the face of the card; other states add a social security number; and some even include signatures, photo jpeg images, digital fingerprints, and face recognition templates.
Whatever is there, we will archive it (even if it seems useless at first, because you just never know). As IDs develop and standards change, we keep up with the times.
