Optical Character Recognition (OCR)
The OCR feature reads the information within the Machine Readable Zone (MRZ). These are found within many documents
including passports, visas and identity cards. The function will work on Stored or Paused images of sufficient quality.
Activating the OCR feature will perform the following functions automatically:
•
Opens the OCR control / information panel.
•
Selects the 780 nm camera filter.
•
Adjusts the magnification to a pre-set setting.
•
Positions a green box at the bottom of the live image.
•
Place the document so the MRZ is within the green box at the bottom of the live image:

Passport Reader
: (If applicable).
Some documents contain an RFID (Radio Frequency Identification) chip. Passports that have this chip have the e-passport logo on the
front cover. The chip reader is an optional extra, and must be attached to the PC before opening the VSC software.
To read the chip, click on the e-passport icon then follow the on-screen instructions. You must place the document on the chip reader
before
clicking ‘
OK
’. If the MRZ on the document matches its counterpart on the chip, the image will appear in blank image area. The
user can then choose to save or print the image and bio data, copy
the data to clipboard, copy the image to clipboard or send the image and information directly to the
Working Folder
(p. 68).
Note: Before attempting to read the e-passport chip, the MRZ data must be successfully read first, as
