Postman Shows How Intelligent Letter Sorting Machine Sorts Mail

Royal Postman Josh Wapiano says this is his last week as a working mailman, so he’s decided to show the engineering secret of the post office. The ILSM, or Intelligent Letter Sorting Machine, does all the dirty work for people these days. 

The amazing machine processes multiple letters a second, deciding where around the country to send them. It has even learned to read bad handwriting over time.
