What Is Iris Identification?

Iris reader technology is extremely secure and safe for end users. There are multiple examples why iris technology is superior to fingerprint, hand geometry and other biometric physical access readers. Below is a bullet list of features and benefits of using iris readers for physical access.

Non-Invasive and is commonly confused with "retinal" scanners; iris cameras do not use a laser.
Iris technology utilizes an infrared digital camera (similar to your personal digital camera) to capture your eye's iris.
Hands free operation eliminates cross contamination from end users (unlike hand & fingerprint readers).
Iris readers can be installed in an offline or online environment.
Use "something you are", "something you have", and "something you know" with your iris device. Use the following scenarios for secure authentication:
- Iris template only
- Iris template plus pin number
- Iris template plus ID card
- Iris template plus ID card and pin number
Iris readers can be installed in pre-existing access control systems the same way a standard door reader is installed.
The camera identifies over 240 unique points of interest for the template that can be stored on your existing ID card, server or iris device.
Iris data templates require only 512 bytes of storage.
This non-invasive method can authenticate an enrolled end user in less than 2 seconds.
The chances of having a duplicate template?

Pre-Printing Card Options

Pre-Printing Card Options:
There are numerous types of ways to print onto a plastic identification card. The three most popular pre-printing options are:

Lithographic
High Definition, Digital Press
Dye Sublimation

Lithographic printing: Lithographic printing is ideal for large quantity runs of over 5,000 cards. The printing is extremely high quality and it offers a 3,000 DPI resolution. The cards are manufactured from large plastic sheets (28, 56, 70 cards per sheet - figure 1) and then are cut down into individual cards. The cards get built up through different layers of materials including: Clear Plastic, PVC and PET (see figure 2). Lithographic presses have the ability to print a large number of colors, including specific spot colors (often called PMS or Pantone colors). Some lithographic presses still use hard copy proofing methods; however most have been updated to be fully digital proofs.

High Definition/Digital Press: High Definition or Digital Press printing is ideal for low to mid-level quantities from 500 up to 10,000 cards. This process offers up to 3,000 DPI print resolution. The main difference from Lithographic is digital press plastic sheets are usually only 21 cards per sheet. End users can utilize multiple colors for their cards and incorporate PMS (Pantone) colors for their unique and custom branding. The proofing process has always been digital with high definition digital presses.

Dye Sublimation: Dye sublimation printing is done one card at a time on pre-assembled ID cardstock. This printing method is generally used for low volume printing. The dye sublimation process will apply color to the cardstock one color at a time: Yellow, Magenta, Cyan and then Black. Since this process only uses a four color process it is not able to match PMS (Pantone) colors. This process is excellent for quick turn projects, low quantities and variable printing jobs.
