 Additionally, machines with a recent Optical Character Recognition (OCR) upgrade have the capability to read the address information, including handwritten, and sort the mail based on local or outgoing ZIP codes.Mail with typed addresses goes to a Multiline Optical Character Reader (MLOCR) which reads the ZIP Code and address information and prints the appropriate bar code onto the envelope.Mail (actually the scanned image of the mail) with handwritten addresses (and machine-printed ones that are not easily recognized) goes to the Remote Bar Coding System.
