TigerTag+

Purpose

The + means identified. A TigerTag+ is a TigerTag whose identity carries a product ID from the official catalogue — not values someone typed, but the exact product: brand, colour, material, temperatures, diameter, SKU, EAN, straight from the source. On top of that it can carry optional enrichment metadata, served by the Web API and improvable after the chip is written.

The chip itself stays 100 % offline. Everything needed to print is on it, exactly as on a standard TigerTag — the catalogue ID adds the ability to look up richer, fresher data when you happen to be online, and takes nothing away when you are not. A TigerTag+ read in airplane mode behaves like any other TigerTag.

And “online” is not a requirement either. The whole reference is published as one file — every id of every filament in the database, free for anyone to copy and mirror — so a reader holding it resolves a catalogue ID with no network at all. See the Web API.

This is the same + as in TigerData+: in both cases it means this identity is a real catalogue product, and in neither case does it mean certified.

Naming note: formerly sold as “TigerTag Pro” — the name is now TigerTag+.

What the `+` adds

	TigerTag	TigerTag+
Print data, on the chip	✅	✅
Works fully offline	✅	✅
Catalogue product ID, on the chip	—	✅
Enrichment metadata, via the Web API, optional	—	✅
Who can produce one	everyone	everyone

The enrichment metadata is the one row that does not live on the chip. It is looked up from the catalogue when you happen to be online, and it can improve after the chip is written — which is precisely why it can never be something the chip needs. Everything the printer requires is on the chip, which is what keeps every level 100 % offline.

The signed variant

A TigerTag+ that additionally carries a cryptographic signature is a TigerTag+ Certified — the level that can prove a spool’s origin, and the only one restricted to certified manufacturers. Verifying a signature stays free and offline for everyone.

Where it sits

flowchart LR
  CAT[("Official catalogue")] -- "product id + metadata" --> TTP["TigerTag+"]
  TTP -- "signed by a certified manufacturer" --> CERT["TigerTag+ Certified"]
  CERT -- "verify offline, public key" --> ANY["Any reader, any phone"]
  TTP -- "read offline" --> ANY

Backing up a chip — a separate feature

Tiger Studio can back up a chip’s exact content in your account, keyed to its physical UID, and later reprogram it back to that state. This is useful and unrelated to the +: it applies to any chip you can scan, and having a backup does not make a chip a TigerTag+.

Factory-state restore: if a chip is accidentally rewritten or corrupted, put it back exactly as it was — signature included, if it had one.
Same chip only: the restore is valid on the original chip, because the backup is bound to its UID. A safeguard for that chip, never a way to clone.
Proof of possession: a scan matching the backup shows the original chip is physically in your hands.

Note: creating a backup currently requires Tiger Studio + a USB reader (TigerPOD / ACR122U); mobile support is planned.
