Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting is required.

This document replaces GB/T 35420-2017 "Storage of Ecode in QR code for Internet of Things Identification System".

Compared with 2017, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) The data structure type of Ecode has been changed (see Chapter 5, Chapter 5 of the 2017 edition);

b) Added the encoding data structure of Ecode-V0 (see 6.1);

c) The user area of the Ecode-V1, Ecode-V2, and Ecode-V3 coding data structures has been deleted (see 6.1 of the 2017 edition);

d) The start character of the attribute area, the DCI start character and the DCI end character are deleted (see 6.2.2 of the 2017 version);

e) Added the URL data structure of Ecode-V0 (see 7.1);

f) Changed the leading character “?” in the unique identification area of the Ecode-V1, Ecode-V2, and Ecode-V3 URL data structures (see 7.2, 2017 7 of the 2001 edition);

g) Added the leading characters "?", " This document is proposed and coordinated by the National Article Coding Standardization Technical Committee (SAC/TC 287).
