NTAG213 Overview
As an NFC Type 2 tag, the NTAG213 belongs to the broader family of passive contactless memory tags that harvest operating energy from the RF field of an NFC reader or smartphone. The NTAG21x family (NTAG213/215/216) is NXP's mainstream product line for NFC tags; within that family, NTAG213 is the lowest-memory variant. Type 2 Tags sit below NFC Type 4 Tags (ISO/IEC 14443-4 compliant) in the NFC Forum tag hierarchy and are optimized for simple, low-cost, high-volume tap-and-read use cases rather than secure transactions.
Key features of the NTAG213 include a 7-byte unique identifier (UID), a 32-bit password-based protection mechanism with password attempt counter, a 24-bit one-way programmable (OTP) memory area, an ECC-based originality signature for anti-cloning support, a built-in NFC counter (NTAG213 also exposes the ASCII mirror and UID ASCII mirror pages), and a true anti-collision loop that allows multiple tags to be inventoried in the field simultaneously. Read range is typically up to 10 cm depending on antenna geometry.
Technically, the NTAG213 implements a half-duplex, 106 kbit/s data rate over ISO/IEC 14443 Type A modulation. The internal memory is organized into user memory (144 bytes) plus configuration pages, with write endurance rated for 100,000 cycles per page and data retention of 10 years per the NXP datasheet. The IC operates without any external power source: the analog front end and on-chip rectifier derive all operating current from the reader's RF field.
Typical applications include smart out-of-home and print media advertising, Bluetooth pairing / Wi-Fi hand-off companion tags (NFC Forum NDEF handover), product authentication labels via the originality signature, NFC shelf labels in retail, business card / SoLoMo tap-to-action tags, and game figure integration (NTAG213 is used in many Bluetooth-paired toys and is one of the memory options for NFC Forum NDEF-based consumer uses).
When designing with NTAG213, observe the antenna matching guidance in the NXP application notes: a recommended etched or printed coil antenna of roughly 35 mm x 35 mm to 45 mm x 45 mm delivers the typical 5-10 cm read range on a mobile phone reader, and a tuning capacitor in the 15-25 pF range compensates the loop inductance. Keep sufficient clear space around the antenna, and avoid placing the tag directly on metal surfaces without a ferrite shield.

Typical Applications
NTAG213 is suitable for 6 applications: Smart Out-of-Home Advertising, Bluetooth Pairing Companion Tag, Product Authentication / Anti-Counterfeit Label, NFC Shelf Label in Retail, SoLoMo / Tap-to-Action Business Card, Industrial / Asset Tracking.
Smart Out-of-Home Advertising
The NTAG213 fits smart out-of-home and print advertising because it is fully NFC Forum Type 2 Tag and ISO/IEC 14443 Type A compliant, exposing 144 bytes of NDEF user memory sufficient to encode a short URL or text record. When a consumer taps a poster or transit shelter with an NFC-capable phone, the reader harvests power from the phone's RF field via the NTAG213's on-chip rectifier, so no battery is required. The standard 106 kbit/s data rate ensures sub-second tap latency, and the 7-byte unique UID supports per-tap analytics on the URL the tag rewrites. Read range of ~10 cm on a properly tuned 45 mm antenna is consistent with body-worn smartphone geometries. The ECC originality signature also lets brands verify that an inlay carries authentic NXP silicon rather than a counterfeit clone when handling brand-protection escalations.
Recommended
Bluetooth Pairing Companion Tag
NTAG213 is widely deployed as the NFC companion tag inside Bluetooth speakers, headphones, and consumer toys that need a one-tap pairing experience. When the user taps the device, the NTAG213 delivers an NDEF Bluetooth Handover Select record via the NFC Forum NDEF handover specification, allowing the host MCU or Bluetooth SoC to complete pairing without manual menu navigation. The 144-byte memory is more than enough for a handover record plus a static NDEF message; the 32-bit password and attempt counter prevent unauthorized rewriting of the pairing payload. The same harness used in NTAG213 tags is reused across the family, simplifying dual-source manufacturing between NTAG213, NTAG215, and NTAG216 variants when different memory capacities are required.
Recommended
Product Authentication / Anti-Counterfeit Label
Anti-counterfeit deployments benefit from the NTAG213's programmable ECC-based originality signature, which lets a brand's authentication app verify that the underlying silicon is genuine NXP rather than a generic ISO/IEC 14443 Type A clone. The 32-bit password plus 8-bit attempt counter prevents trivial rewriting of the NDEF URL that links to the brand's verification service, and the 24-bit OTP memory supports one-time consumption tokens at promotional events. With a 7-byte UID per tag and 144 bytes of user NDEF memory, brands can issue per-unit unique URLs that double as both an authentication gesture and a marketing landing page. The 10-year data retention typical of NXP NFC silicon keeps the tag usable across the brand's required product lifetime.
Recommended
NFC Shelf Label in Retail
Electronic shelf labels in retail leverage NTAG213 when a customer-facing phone tap should reveal product information, reviews, or an end-cap promotion. The 144-byte NDEF memory can hold a deep-link URI plus a short text descriptor, and the Type 2 Tag compliance guarantees that any modern Android or iOS reader app can open the link without proprietary app installation. Retailers frequently migrate from NTAG213 to NTAG215 or NTAG216 when richer content (e.g., embedded JSON or extended SKU data) is needed, which is straightforward because all three share the same command set and antenna form factor. The asynchronous write capability and 100,000-cycle write endurance typical of NXP NFC memory are suitable for environments where the label content is rewritten weekly.
Recommended
SoLoMo / Tap-to-Action Business Card
NTAG213 is the standard IC inside NFC business cards that should trigger a vCard download, calendar invite, or social-profile hand-off when tapped against a phone. The 144-byte user NDEF capacity holds a typical vCard payload with margin. NTAG213 supports the UID ASCII mirror, allowing a host MCU or an iOS Shortcut integration to use the 7-byte UID as a deterministic identifier for the cardholder without first reading NDEF contents. The 100 mm read range on a typical credit-card-sized printed antenna comfortably accommodates the 50-70 mm gap between a held card and a phone, and the Type 2 Tag compliance ensures the tap triggers the phone's native NFC reader without a separate app.
Recommended
Industrial / Asset Tracking
NTAG213 is suitable for low-cost, single-tap asset labels in industrial environments: each tag is encoded with a unique URI pointing to the asset's CMMS record, and field engineers tap the tag with a phone or rugged NFC reader to retrieve the asset history. The contactless, passive nature of NTAG213 means no battery maintenance is required over the tag's service life, and the wide operating temperature range supported by NXP silicon allows deployment in non-climate-controlled warehouses. For tamper-evident deployments the 32-bit password can lock the NDEF page from unauthorized rewrite, while the originality signature lets integrity audits verify authentic NXP silicon. For higher-memory industrial use cases, NTAG215 and NTAG216 are drop-in upgrades in the same footprint and tooling.

- Cross-brand drop-in option (vs FM11NT022)
Design Notes
Estimated: do not place a bare NTAG213 inlay flush against a metal surface without a ferrite backing sheet; the metal shorts the H-field of the 13.56 MHz reader and the read range collapses to a few millimeters. Either recess the inlay by 1-2 mm above the metal or apply a flexible ferrite layer (e.g., TDK IL-10 or equivalent) between the antenna and the metal.
Antenna geometry drives read range more than any silicon parameter. For a printable coil delivering ~100 mm read range on a phone, target an etched loop of 35-45 mm on a side, 3-4 turns of ~0.5 mm trace width, and a tuning capacitance of 15-25 pF in parallel with the coil. Match antenna impedance to ~50 ohm reactance at 13.56 MHz using the NXP datasheet guidance plus the AN11295 antenna design note.
Estimated: keep a clear keep-out region of at least 4-5 mm around the antenna perimeter free of metal pours, copper traces, and via stitching. A broken ground plane directly under the antenna also helps avoid detuning. If the antenna and host controller (e.g., an NFC frontend or MCU) sit on the same PCB, place the antenna loop at the end of the board opposite to noisy digital circuitry to maximize read range.
When using NTAG213F with the FD (Field Detect) pin wired to a host MCU, debounce the FD signal with a 1-10 ms RC filter or a software debounce routine; ambient stray fields during reader polling can produce short FD pulses that the host can otherwise misinterpret as tag-presence events.
