Reading Handwriting:
By 1997, Optical Character Recognition (OCR) software could recognize handwritten block letters and translate them into code, then double-check the address against a database of known addresses and names.
Of course, some handwriting is so bad that it challenges even the best machines. When this happens, an image of the letter is sent to a Remote Encoding Center located hundreds or even thousands of miles away, where workers read and decipher the scanned images. Then they return that information to automated machinery that applies the appropriate routing barcode and moves the mail piece back into the mail stream.
