ISO 14223-3:2018 describes the information that is stored in the advanced transponder memory, its format and the procedures for accessing such information.

This document defines two parts of memory:

a) the fixed part (mandatory):

1. ISO 11785 data field;
2. Data_Config field;

b) the user part (optional):

1. field of fixed allocation for defined data;
2. uses an Object Identifier for data field separation in order to have maximum flexibility for future requirements.
