The method introduced above with accuracy level at 99.92% can satisfy most of the clients. With “Double Entry Single Compare”, the accuracy rate can be further raised to 99.95% for clear printed matter documents.
Two data entry operators (A & B) key in the data and generate the output files: File A & File B.
A QC operator (C) compares these two files through the compare software. When it shows any discrepancy between the two files, C duly corrects the mistakes and generates File C.
For printed matter source documents, an accuracy level of 99.95% can be achieved through this process.
