Kim Cameron on Fingerprint readers

Read the post: Fingerprint charade.

Identification is only possible by physically verifying that my finger embodies some fingerprint. Without physical verifcation, what kind of a lock does the fingerprint reader provide? A lock which conveniently offers every thief the key.
