It’s amazing to me how the US Postal Service sorts mail. It receives such a varied assortment of letters and packages¬†with addresses that are sometimes illegible even to a human. And yet, the USPS’s Advanced Facer-Canceller System (AFCS) can read it, sort it, rotate it, and then push it to the right mail carriers for delivery at a fraction of a second. On top of all of that, it’s even more amazing that there aren’t chronic paper jams at these facilities due to bulk packaging, irregular envelope sizes, etc. (especially given the rate at which¬†this mail flies through the USPS system).
