How to use the Authenticator CF
The machine readable zone
ICAO Doc 9303 requires that machine-readable data of a document be available
within a specific zone. The MRZ is a defined rectangle situated exactly at the
lower edge of the document:
• 23.2 mm (0.91 in) height from the lower edge of the document
• Over the total width of the document
• It spans two lines and each line is 44 characters long
Figure 4.1 The machine readable zone
The document contact area of the D SCAN AUTHENTICATOR CF goes beyond
the ICAO-MRZ. In customer specific applications, it is also possible to read zones
outside the MRZ of documents which do not meet the requirements of ICAO Doc
9303.as long as the physical conditions (font, size, printing quality, lamination,
etc.) of the document to be inspected allow this.

An instruction label on the cover provides schematic information for the user to
