Systems and methods for recognition of encoded information on documents are disclosed. According to an aspect, a system includes a document reader configured to read encoded information from a document, and to output an electrical signal representative of the encoded information. The system also includes signal conditioning modules that are each configured to receive the electrical signal, and to condition the received electrical signal differently for outputting a plurality of conditioned electrical signals. Further, the system includes an information recognition module configured to analyze each of the conditioned electrical signals and to select one of the conditioned electrical signals for use in recognizing the encoded information.
