Compared with ISO /IEC 19794-10.2007, this document has many technical differences, in the outer margin of the clauses involved

Marked with a vertical single line (|). These technical differences and their reasons are as follows.

--- Added the definition of the scope and applicability of the compliance test method in the scope (see Chapter 1);

--- Delete the term "living collection" of ISO /IEC 19794-10.2007, because the term does not appear in this document;

--- Deleted the term "pixel" in ISO /IEC 19794-10.2007, which is a common term and does not need to be defined repeatedly;

--- Added the terms "biometric data exchange record" (see 3.3) and "tested implementation" (see 3.8) to facilitate the understanding of this document.
