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.
