ABSTRACT:
A redundant character recognition system which minimizes both read failures and ambiguities caused by conflicting read signals by merging character recognition signals from MICR, OCR and Bar-Code read heads to produce a single data stream for automatic sorting of a constant velocity train of documents. In the event the MICR and OCR readers are unable to identify a character image, a Bar-Code reader is used to supplement MICR/OCR data by replacing MICR data field rejects with bar-code data field recognition signals. When rejects are generated from both the MICR and bar-code data fields, only self-checking fields within the bar-code data field are merged upon a successful self-check test being performed. If self-checking errors occur, the MICR read data is restored.
