Copy of (7/30/26 Draft Version) Age Verification for ISO 18013-5 - Command 0x1202

The host uses this command to start Age Verification through mobile document transaction.

The sequence of events for transactions with device (mDOC Reader) enabled is roughly as follows.

Command 0x1202 is a subset of Command 0x1201. It only allows a request item, Age over 18, 21 or 25. It only supports ISO 18013-5 specification. The rest of the features are the same.

The device sends a response in the format below, and waits for the mDOC Holder (Apple, Android or other phones) to present a Data Engagement method, either QR Code or NFC. The data exchanged during the Data Engagement phase will be used to generate multiple keys for the encryption/decryption of mDOC messages. The ephemeral key generation algorith is defined in ISO-IEC-18013-5.

After the mDOC Holder presents data engagement method, the device sends Notification 0x0101 - Transaction Information Update to report the Data Engagement status. If Data Engagement phase has completed successfully, then go to the next step to handle Data Retrieval phase. Else, exit with failure.

The device will connect to the mDOC holder through BLE connection. The device will build the “mdoc request” message based on the settings of the command string below. The mDOC Holder will send back the “mdoc response" to the device. The device will decode the CBOR encoded response message.

The device will authenticate the “mdoc response" message with a pre-loaded certificate. The device will verify the SHA-256 hash of all the response items to validate the Data integrity. If the security validation has completed successfully, the device will send the results to the host through Notification 0x0101. Otherwise, the device will send a failure message through Notification 0x0101.

Host may set up the A4 TLVs to enable/disable/select the proper Audio Cue during operation.

Value / Description

Typ

Req

Default

This parameter defines how long the device waits for the completion of this command..

· 0x00 = No timeout

· 0x01 to 0xFF = 1 to 255 seconds

This parameter defines the options of age verification.

· 1=18, 2=21, 3=25 years old.

· 00, 04-FF: Reserved

It defines the security of the 0xFD Data Container. If security is enabled, Data Container will be Encrypted and MACed.

· 0x00, security is disabled.

· 0x01, security is enabled.
