This part is the fourth part of GA 426.

This section instead of GA 426-2003 "Automatic Fingerprint Identification System Data Exchange File Format" Appendix B (normative). 2 Class logic records send field fingerprinting data. Not superseded elsewhere in GA 426-2008 Fingerprint Data Interchange Format.

This part of GA 426-2003 Annex B (normative) compared to the following changes.

--- Modify the field fingerprint text message data item content and format;

--- Increasing the survey management data items;

--- Removed Appendix E (normative) ANSI information exchange code, the definition of delimiters modified to direct reference GB/T 1988-1998.

3 Terms and definitions

GA 773-2008 established terms and definitions apply to this section.

4 Field fingerprint information record structure

Each on-site fingerprint information record may convey one or more fingerprint information in the on-site fingerprint. Fingerprint information includes fingerprints Information, fingerprint characteristic information, fingerprint custom information and fingerprint image information. If you send more than one fingerprint information, use the record between the fingerprint information Delimiter "GS" separated. The last byte of the logical record is the end of file "FS".

5 Field fingerprint information record data item name and format
