Division 4 Use of one or two fingerprints for biometric verifications

Member States may decide to use one or two fingerprints flat for biometric verifications, instead of four fingerprints.

The following fingers shall be used by default:

1. (a)

   One finger: index finger (NIST identification 2 or 7),

2. (b)

   Two fingers: index finger (NIST identification 2 or 7) and middle finger (NIST identification 3 or 8).

In addition the following fingers may be used:

1. (a)

   One finger: thumb (NIST identification 1 or 6) or middle finger (NIST identification 3 or 8),

2. (b)

   Two fingers:

   1. (i)

      index finger (NIST identification 2 or 7) and ring finger (NIST identification 4 or 9) or

   2. (ii)

      middle finger (NIST identification 3 or 8) and ring finger (NIST identification 4 or 9).

For ergonomic, standardisation and visualisation purposes, fingerprints from the same hand shall be used, starting with the right hand.

The finger-position shall be identified for each individual fingerprint image as specified by the ANSI/NIST-ITL 1-2000 standard.

When such finger-position identification is not possible or it proves to be erroneous, national systems may request verifications in CS-VIS involving the use of ‘permutations’.

Missing or bandaged fingers shall always be identified as specified by the ANSI/NIST-ITL 1-2000 standard and the VIS Interface Control Document.
