ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONTable 55 EFS codes for types of corresponding points and featuresCategory Type Code DescriptionDefinitecorrespondenceFeaturePointFPThe labeled feature definitely corresponds to the specific featuredefined by the Field Number and Field Occurrence informationitems. (X and Y information items are unused)The labeled feature definitely corresponds to the location withthe coordinates defined in the X,Y information items. (FieldNumber and Field Occurrence information items are unused)Possible ordebatablecorrespondenceDebatableFeatureDebatablePointDFDPThe labeled feature may debatably correspond to the featuredefined by the Field Number and Field Occurrence informationitems. (X and Y information items are unused)The labeled feature may debatably correspond to the locationwith the coordinates defined in the X,Y information items. (FieldNumber and Field Occurrence information items are unused)Definite lack ofcorrespondenceDoes notexistXThe labeled feature definitely does not exist in the impression,and the consistency of presentation of the potentiallycorresponding region is sufficient to make a definitedetermination. The X,Y position may be used to optionallyindicate where the absent feature would have been expected. 99InconclusiveOut ofregionUnclearareaRUThe labeled feature is not visible in the impression because itlies outside of the area of correspondence for this image: thefeature may or may not be present, but the impression does notinclude the relevant area (X, Y, Field Number, and FieldOccurrence information items are unused)The labeled feature is not visible in the impression because thepotentially corresponding region is not sufficiently clear: thefeature may or may not be present, but local quality issuesprevent a definite determination. (X, Y, Field Number, and FieldOccurrence information items are unused)8.9.7.49 Field 9.362: EFS examiner comparison determination / ECDThis optional text field indicates an examiner’s determination based on analysis andcomparison of two specified friction ridge images. If multiple examiners’ determinationsare represented, each is contained separately in a repeating subfield. Comparisondeterminations against multiple impressions in the same transaction are specified in aseparate subfield with distinct IDC references. Each subfield consists of at least seveninformation items. The eighth and ninth information items are optional:99[2013n>] In order to allow an examiner to demonstrate the lack of correspondence for a feature thatdoesn't exist, the text has been changed from the 2011 version, which stated: “(X, Y, Field Number, andField Occurrence information items are unused)” [
