Bar Codes date back further than you think (the 1940s) in industrial applications, and were in regular commercial use by the late 70s once the Universal Product Codes were agreed on.
Columbia could well have had bar codes on their student IDs by then, but I don't know if they really did.
I have no idea if they did. But thought a poster here debunked the picture saying that bar codes were not used on student ID’s at that time.
