Memory structure
The SRTAG2K-D supports the NDEF Tag Application as defined in the NFC Forum Type 4
Tag. The SRTAG2K-D is composed of three files:
• One Capability Container file
• One NDEF file
• One System file: this is an ST-proprietary file
The System file contains some information on the configuration of the SRTAG2K-D device.
The CC file gives some information about the SRTAG2K-D itself and the NDEF file. The
NDEF file contains the User data.
File identifier
The file identifier is the value used in the Select command to select a file.

CC file layout
The CC file gives some information about the SRTAG2K-D and the NDEF file. This file is a
read-only file for the RF host and cannot be modified by issuing a write command.
The T field, Read Access and Write Access fields can be changed by the RF host by issuing
a specific process (refer to Section 7: Functional procedures).
