This technology would supposedly allow a student to go through the check out line and not encounter any human error or delay. However, I understand that these are technical problems that may be easily solved and do not change my support for such an absolute identification system. I thought longingly of a future in which I could just walk up to that machine and it could somehow identify me immediately and give me the money. For example, one could be identified through an iris print because the patterns on the human iris are fixed and can be captured with a standard video camera. Another method that may be used in the near future to identify people is the facial thermogram.
Facial thermograms use the patterns of veins and arteries beneath the skin for identification.
Even though I have to admit that the idea of absolute identification is frightening, I still believe that it is somewhat inevitable and may be the only thing that can stop such serious crimes as identity theft. The first point is that discrimination is likely to occur. His example is that if photographs were to be used in an overall identification system, skin color could be easily included in a loan approval program or similar program as a factor for approval. Currently, in approval processes, such as a loan approval, the approval officer may have already subconsciously added skin color as a factor in his decision.
