50 Photos of Random But Interesting Things to Add to Your Knowledge Bank

We all use credit and debit cards these days. Chip reader technology has come out in recent years, replacing the previous magstripe on the back of cards. But do we actually know how they work? Credit and debit cards come with shiny designs and smooth exteriors, but someone was curious to find out what was underneath.
