3 Terms and definitions

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

4 String search results of the candidate information record structure

Each string search result candidate information record may convey one or more string search result candidates for a field fingerprint. on site Fingerprint image information, feature point information and custom information using the third type of business logic record transfer, record format, see GA 426.4-2008. If multiple fingerprint information is transmitted, the fingerprint information is separated by the record separator "GS". The last byte of the logical record is the end of the file Character "FS".

5 String search results of the candidate information record data item name and format

String comparison results of the candidate information record data item name and format in Table 1.
