how have bar codes been modified?
were barcodes first in the shape of a bull’s eye? like round black and white lines in a circle? how have people made them better since they were first invented? have they changed at all? having a hard time finding it on the net. everything just keeps saying genetic barcodes. ugh. thanks in advance for your help!!!!!!!!!
Best answer:

en.wikipedia.org/wiki/Barcode
It looks like they have evolved quite a bit over the years..
