摘要： An improved document or ID card scanner for imaging documents and decoding coded indicia such as bar codes and magnetic strips is disclosed. The scanner incorporates an internal motor and automatic multi-pass scanning function to quickly and accurately capture all data on a document. During these passes the document is imaged under a number of different lighting conditions and a magnetic strip is read multiple times. The document scanner can perform scans as the document moves in forward and reverse directions; and each scan occurs at a speed optimized to the particular scanning method and direction of the current pass. During the multiple passes, the document is scanned and or read at varying speeds for reliability and for different purposes as detailed herein.
