Transponder as well as optical 2D-Codes are data carrier for information usually displayed in bits and bytes. But the contained information could be organized in a certain structure. How to do this in a norm conforming way is described in the standard ISO/IEC 15434 “Syntax for high capacity ADC Media” (ADC stands for Automatic Data Capture).

The two most prominent data structures in use are following the rules of GS1 and the ASC MH1. They are described in the standard ISO/IEC 15418 (Data Identifier and Application Identifier).

It is the purpose of these international standards to define the syntax for high capacity ADC media (such as transponder or 2D-Codes), in order to enable ADC users to utilize a single mapping utility, regardless of which high capacity ADC media is employed.

The interoperability of different data structures is achieved by the definition of a Message Header and a Format Header. While the Message Header defines the start and the end of the data contained, the Format Header indicates which data format is used.

Below two examples are shown for a GS1 and an ASC data format.

For RFID the data structures are controlled by AFIs (lower 8 bits of PC) when ISO format is used according ISO/IEC 15961-2 and -3. Depending on the AFI different data compression methods may be used. Details are described for example in ISO 17363, 17364, 17365, 17366 and 17367.
