Appendix B: Vision
Verification Module
This appendix provides information about using the Vision
Verification module to verify that the correct card stock has been
loaded, to verify that the card has been personalized correctly, or
both.
Introduction
The Vision Verification module for the Maxsys or MX6000 Card Personalization
System is an inline camera, lighting, and capture module for card stock
verification and quality assurance. It compares pre-printed or personalized
elements on the front side, back side, or both sides of the card to a pre-defined
file, a data element, or the contents of a live data stream. The Vision Verification
module verifies a wide variety of elements, including:
• Windows® TrueType® fonts
• Pre-printed graphics
• Laser images and graphics
• OCR-B font
• MRZ characters
• Custom font designs
The Vision Verification module can be positioned immediately after the Card
Input or Card Cleaning module (for card stock verification) or after all
personalization modules (for quality assurance). There can be two Vision
Verification modules in a Maxsys or MX6000 System to handle both functions.
The Vision Verification module compares some element of the card stock or
finished (personalized) card to either a static value or a dynamic variable. The
result of the comparison is a Score that is compared to a Threshold Value that you
establish. If the Score is less than the Threshold Value, the card is rejected.
More stringent (higher value) Threshold Values theoretically create more card
rejects. There are trade-offs between unnecessary card rejects (false rejects) and
missed errors, but because you set the Threshold Value, you can determine which
trade-offs you are willing to make.
