## What makes TigerTag unique

**1 — Proof of authenticity (ECDSA-P256)**

TigerTag is the **only material RFID protocol to offer cryptographic proof of authenticity**.
Each signed chip carries an ECDSA-P256 signature that binds the chip UID to the product data.
Any reader — including this SDK — can verify the signature fully offline, with no server call:

```python
result = tag.verify()   # ✅ VALID — chip is genuine and untampered
                        # ❌ INVALID — data has been modified or chip is cloned
                        # ⬜ NOT SIGNED — unsigned Maker tag (verification not required)
```

No other RFID material protocol provides on-chip cryptographic authentication at this level.

**2 — Chips reusable forever**

TigerTag chips are **never write-locked**. Once a spool is finished, the chip gets a second life:

- Erase and reprogram as a fresh TigerTag for a new spool: `TigerTag.erase()`
- Reprogram with any NFC / NDEF standard for a completely different use case
- Use as a plain NTAG tag in any NFC-capable application

Zero electronic waste. The chip is a permanent, reusable asset — not single-use packaging.
No competing protocol offers this combination of authentication and unlimited reusability.

**3 — Remote update by the manufacturer (TigerTag+)**

TigerTag+ is the **only material RFID protocol with remote over-the-air update capability
for manufacturers**. When a filament or material brand publishes improved print settings,
corrected temperatures, or updated material data to the TigerTag cloud API, every chip
already deployed in the field can receive those updates — without recalling a single spool:

```python
# On any reader / printer / slicer that uses this SDK:
patched_tag, changes = tag.patch_from_api()   # fetch latest manufacturer data + apply to chip
print(f"{len(changes)} field(s) updated by manufacturer")

# Or inspect what changed before applying:
diffs = tag.diff_api()
for d in diffs:
    print(f"{d.field}: chip={d.chip_value!r} → manufacturer={d.api_value!r}")
```

The update is manufacturer-driven and cryptographically scoped — only the product data
fields can change. The chip UID and signature remain protected. No other RFID material
protocol gives manufacturers this level of post-deployment control over their product data.

**4 — Native HueForge integration**

TigerTag is the **only RFID protocol natively integrated with HueForge**. The TD (Transmission Distance)
value is stored directly on the chip and read by HueForge without any manual entry.
It is also the only protocol supported by **TD1s by Ajax**, the open-source filament manager.

---

## Hardware ecosystem

| Device | What it does | Price |
|--------|-------------|-------|
| **Tiger Scale** | Open-source DIY ESP32 smart scale — reads the TigerTag, weighs the spool, updates `measure_available` in real time | ~30 € in parts |
| **TigerTag Pod** | Plug-and-play NFC reader/writer — read and write chips from your desktop (via TigerTag Studio Manager) or from your phone (via TigerTag RFID Connect on iOS and Android) | — |

The **TigerTag Pod** works with the **TigerTag RFID Connect** app (iOS + Android) for full
mobile read/write access — no soldering, no setup, just plug in and scan.

**Everything is free for end users**: the protocol, this SDK, TigerTag Studio Manager,
the mobile apps, and all community tools. No subscription, no lock-in.

## ▶ Try the Playground

No NFC hardware required — explore the full SDK output directly in your browser.

<img src="assets/badge_playground.svg" width="260" alt="Launch Playground">

```bash
# Start the dev server
python3 tools/server.py 7432

# Open in browser
open http://localhost:7432/tools/playground.html
```

The playground has three panels:
- **Left** — generate TigerTag / TigerTag+ / Init tags with presets or custom values
- **Center** — parsed output cards: Protocol, Material, Colors, Print Settings, Traceability, Cloud API
- **Right** — collapsible SDK panel: `pretty()`, `verify()`, `to_raw_dict()`, `to_dict()`, `raw_api()`, `diff_api()`

---

## Install

```bash
pip install tigertag                    # core only — stdlib, works fully offline
pip install tigertag[sync]              # + requests  (database auto-update)
pip install tigertag[verify]            # + cryptography (ECDSA signature check)
pip install tigertag[full]              # everything
```

Zero configuration. Zero network required on first run. Bundled reference databases ship with the package.

---

## Quick start

```python
from tigertag import TigerTag

tag = TigerTag.from_pages(payload, uid=uid)   # from your NFC SDK
print(tag.pretty())                            # human-readable summary
print(tag.verify())                            # ✅ VALID / ⬜ NOT SIGNED / ❌ INVALID
print(tag.to_dict())                           # JSON-ready dict
```

That's it. Works immediately after `pip install tigertag`.

---

## What is TigerTag?

TigerTag is an **open-source RFID protocol** that stores manufacturing material data directly on NFC chips (NTAG213 / NTAG215 / NTAG216, ISO 14443-3 compatible). No cloud dependency for reading — all data lives on the chip.

**Tag types:**

| Tag type | ID Product | Offline | Cloud |
|---|---|---|---|
| **TigerTag** (Maker) | `0xFFFFFFFF` | ✅ full data on chip | — |
| **TigerTag Init** | `0x00000000` | ✅ blank template | — |
| **TigerTag+** | numeric ID | ✅ full data on chip | ✅ API for live updates |

**This SDK** reads all three types identically. TigerTag+ cloud comparison (`diff_api()`) requires `requests`.

**Protocol spec:** [github.com/TigerTag-Project/TigerTag-RFID-Guide](https://github.com/TigerTag-Project/TigerTag-RFID-Guide)

---

## Constructors

| Method | Input | When to use |
|--------|-------|-------------|
| `TigerTag.from_pages(payload, uid)` | 80 or 144 bytes + 7-byte UID | **NFC SDK integration (recommended)** |
| `TigerTag.from_dump(data)` | 80 / 144 / 180 bytes | Binary dumps, ACR122U raw read |
| `TigerTag.from_file(path)` | path to `.bin` file | Testing, offline batch processing |

**`from_pages`** is the primary constructor for production use. NFC SDKs always provide the UID as a separate property — pass it directly for full signature verification.

**`from_dump` with 180 bytes** (full chip dump including system pages) auto-extracts the 7-byte UID.

---

## Input formats

### `from_pages(payload, uid)` — NFC SDK workflow

NFC SDKs always expose the UID as a dedicated property. Pages 0–3 (system pages: lock bytes, capability container) are never part of the user data payload.

| Payload | Pages | UID | Verifiable |
|---|---|---|---|
| **144 bytes** | 0x04–0x27 (user data + signature) | Required (7 bytes) | ✅ Yes |
| **80 bytes** | 0x04–0x17 (user data, no signature) | Required (7 bytes) | N/A |

### `from_dump(data)` — binary dump workflow

| Dump | Content | UID | Verifiable |
|---|---|---|---|
| **180 bytes** | Full chip (pages 0–44, includes system pages) | Auto-extracted | ✅ Yes |
| **144 bytes** | Partial dump (user data only, no system pages) | Not available | ❌ No |
| **80 bytes** | User data only | Not available | N/A |

---

## Key methods

```python
# Read
tag.pretty(db=None, sig_result=None) -> str        # human-readable summary
tag.to_dict(db=None)                 -> dict        # JSON-serializable, all labels resolved

tag.is_maker          # True if id_product == 0xFFFFFFFF
tag.is_init           # True if id_product == 0x00000000
tag.is_plus           # True if id_product is a valid cloud ID
tag.is_signed         # True if signature bytes are non-zero
tag.uid_hex           # "04AABBCCDDEE11" or None

tag.manufacturing_date# datetime (UTC)
tag.stock_percent     # 75.0  or None
```

---

## Write / CRUD operations

```python
from tigertag import TigerTag

# Build a new tag from scratch
tag = TigerTag.create(
    uid=bytes.fromhex("04A1B2C3D4E5F6"),
    id_material=38219,        # PLA
    id_brand=19961,           # Rosa3D
    nozzle_temp_min=195,
    nozzle_temp_max=230,
    color1_r=255, color1_g=0, color1_b=0, color1_a=255,
    measure=1000, id_unit=21,
)

# Blank TigerTag Init chip (ready for programming)
init_tag = TigerTag.as_init(uid=bytes.fromhex("04A1B2C3D4E5F6"))

# Erase a chip — write the returned 80 bytes to the NFC chip
blank_bytes = TigerTag.erase()

# Immutable surgical update — returns a new TigerTag, original unchanged
patched = tag.patch(nozzle_temp_min=200, dry_temp=55)

# TigerTag+ cloud sync
api_data = tag.raw_api()                    # fetch live product data
diffs = tag.diff_api(api_data)              # what differs chip vs cloud?
patched_tag, applied = tag.patch_from_api() # apply all cloud values
print(f"{len(applied)} field(s) updated from cloud")
```

**Protected fields** — `patch()` raises `ValueError` if you try to modify: `id_tigertag`, `id_product`, `uid`, `signature_r`, `signature_s`.

### ApiDiff

`ApiDiff` is a namedtuple `(field, chip_value, api_value)`:

```python
from tigertag import ApiDiff, TigerTag

tag = TigerTag.from_pages(payload, uid=uid)
diffs = tag.diff_api()

for d in diffs:
    print(f"{d.field}: chip={d.chip_value!r}  →  api={d.api_value!r}")
```

Fields compared: `nozzle_min`, `nozzle_max`, `bed_min`, `bed_max`, `dry_temp`, `dry_time`, `type`, `material`, `brand`, `diameter`, `aspect_1`, `aspect_2`, `color_1`, `color_2`, `color_3`, `measure_g`, `measure_unit`.

---

## Signature verification

```python
result = tag.verify()    # fully autonomous — finds the public key from the bundled DB

result.ok       # True only for VALID
result.status   # "valid" | "invalid" | "unsigned" | "no_crypto" | "no_key" | "no_uid"
str(result)     # "✅ VALID" | "❌ INVALID" | "⬜ NOT SIGNED" | "🔒 NO CRYPTO" | …
result.to_dict()# {"status": "valid", "ok": True, "detail": "…"}
```

| Status | Meaning |
|--------|---------|
| `VALID` | Signature matches — chip is authentic |
| `INVALID` | Signature present but does not match UID + data |
| `UNSIGNED` | No signature bytes — Maker tag or unverified |
| `NO_CRYPTO` | `cryptography` package not installed — run `pip install tigertag[verify]` |
| `NO_KEY` | No matching public key in database for this protocol version |
| `NO_UID` | UID not provided — cannot verify (use `from_pages(payload, uid=uid)`) |

ECDSA-P256 verification uses the public key bundled in `id_version.json` — works fully offline.

---

## Database (TigerTagDB)

```python
from tigertag import TigerTagDB

db = TigerTagDB()                          # bundled database (offline, no network)
db = TigerTagDB(auto_sync=True)            # check for updates on init
db = TigerTagDB("/path/to/custom/db")      # custom database path

db.material(38219)     # {"id": 38219, "label": "PLA", "density": 1.24, ...}
db.brand(1)            # {"id": 1, "label": "Generic", ...}
db.version(0x01000001) # {"id": ..., "label": ..., "public_key": "-----BEGIN..."}
TigerTagDB.label(entry)# safe label extraction helper
```

### Auto-update behavior

The SDK ships with bundled reference databases — works fully offline after `pip install tigertag`.

| Mode | Behavior |
|------|----------|
| Default | Uses bundled JSONs — no network, always works |
| `TigerTagDB(auto_sync=True)` | Checks timestamps on init, downloads only changed files |
| `tag.sync_db(force=True)` | Forces full re-download |
| `tigertag --sync-only` | CLI sync, updates bundled database in place |
| Network failure | Caught silently — bundled databases used as fallback |

Sources: TigerTag API → GitHub mirror (automatic fallback).

---

## NFC SDK integration

`from_pages()` accepts exactly what NFC SDKs provide:

```python
# Android (NfcA / MifareUltralight)
uid     = tag.id                           # ByteArray → bytes
payload = mifare.readPages(4, 39)          # 144 bytes

# iOS (CoreNFC)
uid     = tag.identifier                   # Data → bytes
payload = tag.readNDEF(...)                # pages 4–39

# Flutter (flutter_nfc_kit)
uid     = bytes.fromhex(tag.id)
payload = await FlutterNfcKit.readBlock(4, length=144)

# Python nfcpy / ACR122U
uid     = tag.identifier                   # bytes
payload = tag.read(4, 36)                  # 36 pages × 4 bytes = 144 bytes

tag = TigerTag.from_pages(payload, uid=uid)
result = tag.verify()                      # fully autonomous
```

### ACR122U — full example (nfcpy)

```bash
pip install nfcpy "tigertag[verify]"
```

```python
import nfc
from tigertag import TigerTag

def on_connect(tag):
    uid     = tag.identifier        # 7 bytes — provided directly by nfcpy
    payload = tag.read(4, 36)       # 36 pages × 4 bytes = 144 bytes

    tt = TigerTag.from_pages(payload, uid=uid)
    print(tt.pretty())
    print(tt.verify())              # ✅ VALID / ⬜ NOT SIGNED / ❌ INVALID
    return True

with nfc.ContactlessFrontend("usb") as clf:
    clf.connect(rdwr={"on-connect": on_connect})
```

## Chip memory layout

<img src="assets/chip_layout.svg" width="100%" alt="NTAG chip memory layout — pages 0x04–0x27">

---

## CLI

```bash
tigertag dump.bin              # parse + human-readable output
tigertag dump.bin --json       # output as JSON
tigertag dump.bin --raw        # raw protocol fields, no DB lookup
tigertag --sync-only           # update reference databases and exit
tigertag --version             # show SDK version

python -m tigertag dump.bin    # same, via module runner
```

---

## Standalone single-file usage

For projects where you can't add a dependency — drop `parse_tigertag.py` directly:

```python
from parse_tigertag import TigerTag

tag = TigerTag.from_dump(open("dump.bin", "rb").read())
tag.sync_db()           # auto-download databases (requires requests)
print(tag.pretty())
```

`parse_tigertag.py` is a complete standalone copy — no `tigertag/` package required.
