What is supported now

Read tag information: UID, AFI, DSFID and memory layout
Change UID: set a new 8-byte ISO15693 UID
Change AFI and DSFID: configure both one-byte values from the CLI
Read and write blocks: access the tag’s user-memory blocks

ISO15693 / SLIX Command Compatibility

The following behavior has been verified on this Gen3 80-block tag:

Function	Result
Read Multiple Blocks (0x23)	Supported
SLIX Get Random Number	Supported
Privacy Enable / Disable Commands	Accepted
Actual UID Hiding	Not Supported

Privacy behavior: The tag accepts the SLIX privacy enable/disable command sequence, but enabling privacy does not actually hide or suppress the UID in responses.

RECOMMENDED HARDWARE

PN532Killer

PN532Killer is a multi-protocol RFID tool supporting ISO14443A, ISO14443B, ISO15693 and EM4100. With PN532 CLI, it provides the required hardware interface for configuring this Gen3 ISO15693 tag.

Configure the tag with PN532 CLI

The current open-source CLI supports PN532Killer over USB serial and includes ISO15693 scan, information, block read/write and magic-tag configuration commands.

PN532 CLI connected to PN532Killer changing the UID, AFI and DSFID of a Gen3 ISO15693 tag — PN532 CLI connected to PN532Killer: read the original tag information, change the Gen3 UID, update AFI and DSFID, then verify the new values with `hf 15 info`. Click the screenshot to view it at full size.

Verify the Tag with NXP TagInfo

These Android NXP TagInfo scans confirm the 80-block memory layout and show the updated UID, AFI and DSFID after configuration with PN532Killer and PN532 CLI.

1. Install and start

git clone https://github.com/whywilson/pn532-python.git
cd pn532-python/script
python3 -m pip install -r requirements.txt
python3 pn532_cli_main.py

Connect PN532Killer by USB before starting the CLI. Python 3.9 or later is recommended.

2. Check the tag

hf 15 scan
hf 15 info

The information command displays the current UID, AFI, DSFID, IC reference and block layout. Keep only one ISO15693 tag in the field while configuring it.

3. Change the UID

hf 15 gen3uid -u E004010203040506

Replace the example with the required 16 hexadecimal characters (8 bytes). The UID must begin with E0, as required by the current CLI validation.

4. Set AFI and/or DSFID

hf 15 gen3config --afi 00 --dsfid 00

Option	Meaning	Format
`--afi 00`	Set the AFI value	Optional, 1-byte hex
`--dsfid 00`	Set the DSFID value	Optional, 1-byte hex

Gen3 command behavior
hf 15 gen3uid is designed for the 80-block Gen3 Magic ISO15693 tag and preserves the required blocks 20/21. hf 15 gen3config updates AFI and/or DSFID without locking those fields. Verify the result with hf 15 info after each change.

For authorized research, development and compatibility testing only. This Gen3 tag does not use NFC DirectWrite; UID and configuration changes require the supported PN532Killer + PN532 CLI workflow.
