The Advance Curve Intelligent Envelope Processing System has an OCR camera that reads the address at speeds of up to 6,000 per hour. As the Advanced Curve reads the address it processes the address for CASS, MASS and does the address corrections. The Advanced Curve system calculates the zip plus 4 plus 2 and then sprays the IMB on the bottom of the envelope.
