who first thought of using a plastic bag over the credit card strip when it gets worn?

I've been at a store using my credit card and the strip is a little worn out. I've seen countless clerks grab a plastic bag, hold it over the strip and swipe them together. This always works and seems to be common knowledge. I've always wandered why it works and who first thought of it.

no idea

    I did, right after I invented the post-it. I'm glad I could help.
