What is the size of the iris biometric template?

A non-encrypted iris biometric template is 512 bytes in length.

When encrypted the iris template is approximately 603 bytes in size.

The iData software typically will create and store two iris templates (right and left illuminated) for each eye (4 iris templates per user).

If stored on a smart card, only one iris template will be stored for each eye due to the space limitations of smart cards.
