In the world of Auto ID, biometrics are best for a high degree of certainty (high 98%+) and low rejection rates.
Retinal is not the only way to insure a good biometric without having the usual negatives associated with the more common fingerprint database issues of privacy.

The reason one needs an ID card is to act as the final match in authenticating the official nature of the person being identified.
