Fingerprint scanning. Conceptual computer artwork of a hand touching a fingerprint scanning pad. The pattern of ridges on the tip of the index finger will be compared with a print held on a computer database. The target pattern could represent the use of fingerprint scanning and other biometric parameters, such as iris patterns, to target crime. Fingerprint scanning technology could be used for secure access to particular buildings or computer files, or, in conjunction with passports and identity cards, to verify a person's identity.
