“Never heard of these”, meanwhile I was remembering a credit card that I used so often that I wore the coloring off the raised numbers.
And I guess if one has never seen these, I need to explain. In order to leave an impression on the carbon paper (I should probably explain that, too, huh?), a fair amount of pressure was needed (those old card imprinters didn’t require a gym membership, but a child could not operate one). That rolling pressure would eventually wear on the surface of the card, and turn the numbers white when the outer layer wore through.
If I remember correctly, this sound is part of Pink Floyd's song "Money"... part of the background rhythm. I wonder how many of the "Never heard of these" crowd would recognize it if they hard it in person... smile
