Smart Poster
An NDEF record type that combines a URI record with optional title text, action, icon, and size metadata. Used for NFC-triggered marketing posters where a tap launches a URL with a rich preview.
What Is a Smart Poster?
A Smart PosterSmart PosterCompound NDEF recordNDEF recordSingle data element with TNF, type, ID, and payloadView full → combining URI with title and action metadataView full → is a compound NDEF record (TNF 0x01, type "Sp") that bundles a URI record with optional title, recommended action, icon, and size metadata. The Smart Poster format delivers a richer tap experience than a standalone URI by providing the OS with display and behavior hints.
Structure
A Smart Poster record contains a nested NDEF message:
Outer Record (type: "Sp")
+-- URI Record (mandatory) — target URL
+-- Text Record(s) (optional) — title/description
+-- Action Record (optional) — Do/Save/Open
+-- Size Record (optional) — content size hint
+-- Type Record (optional) — target MIME type
Action Record Values
| Value | Action | Description |
|---|---|---|
| 0x00 | Do | Execute the URI (default) |
| 0x01 | Save | Save for later |
| 0x02 | Open | Open for editing |
Smart Poster vs Plain URI
| Feature | Plain URI | Smart Poster |
|---|---|---|
| URL delivery | Yes | Yes |
| Multilingual title | No | Yes |
| Action recommendation | No | Yes |
| Content size hint | No | Yes |
| Memory usage | Minimal | Higher |
Memory Considerations
Smart Posters consume significantly more user memory than plain URIs:
- Plain URI
https://example.com: ~20 bytes - Smart Poster with URI + English title: ~45 bytes
- Smart Poster with URI + 3 language titles + action: ~90 bytes
On NTAG 213 (144 bytes), a multilingual Smart Poster may consume most available space.
Platform Support
Android: Full parsing. Title displays in NFC scan notification; URI opens on tap. Language selection matches device setting.
iOS: Extracts the URI and handles it as a standard URL. Title text is not displayed by the native handler, though Core NFC apps can access all sub-records.
When to Use
Use Smart Poster for marketing tags needing branded titles, multilingual deployments (tourism, museums), or app-directed taps combined with AAR. For simple link delivery, a plain URI record is more efficient.

The NFC glossary is a comprehensive reference of technical terms, acronyms, and concepts used in Near Field Communication technology. It is designed for developers, product managers, and engineers who work with NFC and need clear definitions of terms like NDEF, APDU, anti-collision, and ISO 14443.
Each glossary term is cross-referenced with related NFC chips, standards, and other terms. For example, the term 'AES-128' links to chips that support AES encryption (NTAG 424 DNA, DESFire EV2/EV3), and the term 'ISO 14443' links to all chips compliant with that standard.
