Rectangular NTAG213 Seal for Deliberate NFC Interaction
Our anti-tamper NFC tag uses an NTAG213 chip and a 38 × 22 mm antenna in a 45 × 27 × 0.3 mm printable white PET label. It is designed for compact package seals, device housings and product labels that require close-range NFC interaction plus resistance to intact transfer.
The published reading distance is up to 1.5 cm in free air. This restricted read zone requires deliberate positioning near a compatible phone or NFC reader and should be tested after the tag is attached to the final product.
45 × 27 mm Rectangular tag size
NTAG213 ISO 14443A chip
White PET Printable face material
Up to 1.5 cm Published free-air range
This PET construction differs from the 26 mm FM11RF08 brittle-paper label. Confirm whether your project requires visible face damage, antenna disconnection, a changed electronic state or a combination of these results after removal.

The target page describes 180 bytes of EPC/block memory and 144 bytes of user memory. Confirm the exact usable layout and encoding method before preparing production data rather than treating these descriptions as separate unrestricted banks.
Choose the Rectangular PET Format for These Tasks
Device Seal Placement
The 45 × 27 mm rectangle can bridge a service opening, housing joint or access point where removal should affect the tag. Verify that the complete 38 × 22 mm antenna stays clear of nearby metal.
Printed Product Identity
The white PET face provides more structured print space than a small round label. It can carry a short serial, QR code, barcode or logo when the artwork remains readable within the available area.
Intentional Phone Interaction
The short read range can support deliberate user interaction at a defined point on the package. Phone compatibility and antenna location should be verified through an actual tap test.
Define the NFC Action Before Encoding
| Required Action | Data to Prepare | Validation Method | Procurement Risk |
|---|---|---|---|
| Open product information | Approved URL or application record | Test the encoded sample on all required phone models. | Phone settings or record format may prevent automatic opening. |
| Identify a device | UID-to-device mapping | Compare the scanned UID with the authorized database. | A UID alone does not prove that the device is genuine. |
| Register a warranty event | Product ID, status rules and server workflow | Test valid, activated, removed and duplicate-item states. | The label cannot independently determine warranty validity. |
| Read stored project data | Field names, byte allocation and permissions | Read back every field using the final software. | Usable memory may be less than a simple total-memory figure. |
| Detect attempted transfer | Required physical and electronic failure state | Retest after partial removal, full removal and reapplication. | Surface-specific peeling may produce a different result. |
Test the PET Tamper Structure, Not Only the Adhesive
Physical Removal Result
The page states that tearing or damage changes the internal antenna structure, but it does not specify a VOID message, residue pattern or guaranteed face rupture. Define the visible evidence needed for your inspection process.
- Required face damage
- Required adhesive residue
- Acceptable removal method
- Expected post-removal appearance
Electronic Removal Result
The target page states that removal can make the tag ineffective or alter its status. These are different electronic outcomes, so sample testing must establish which response the supplied structure actually provides.
- Readability after edge lifting
- Readability after partial removal
- Readability after complete removal
- Response after attempted reapplication
A passive NFC tag does not transmit a removal alert by itself. A user or reader must scan it, and the application must interpret the resulting response or lack of response.
Check the Product Surface and Antenna Clearance
Plastic and Paperboard
Evaluate coatings, mould-release agents, surface texture and curvature. Use the final cleaning and application process because adhesion determines whether removal stresses the antenna as intended.
Metal Device Housings
This model is not published as an on-metal NFC tag. Direct metal contact can detune its antenna. For metal installations, review our HF anti-metal tags or submit the complete mounting structure.
Harsh Environments
The PET face may differ from brittle paper in handling, but no waterproof, UV, temperature, abrasion or chemical-resistance rating is published. Provide actual exposure requirements for review.
Printed and Digital Identity Preparation
| Identity Element | Information to Supply | Approval Check |
|---|---|---|
| Logo and fixed text | Vector artwork, colour and orientation | Legibility within the 45 × 27 mm face |
| QR code or barcode | Code type, data source and required size | Scan performance on finished samples |
| Visible serial | Prefix, length, starting value and sequence | Correct order and duplicate control |
| NFC data | URL, text, identifier or application field map | Readback through approved phones and readers |
| Database relationship | Rule connecting UID, printed serial and item record | Sample mapping before production |
Static printed or NFC data does not prevent copying by itself. Authentication requires an authorized database, application rules and appropriate chip-level security for the project risk level.
Sample Approval Sequence
Define the Tap Action
Specify the required phone or reader response and the data needed by the application.
Apply to Final Surfaces
Use the actual material, curvature, nearby components and production cleaning process.
Verify Printed and NFC Data
Check all visible identifiers and read the programmed data with approved devices.
Test the Removal Outcome
Inspect and rescan after edge lifting, partial peeling, removal and reapplication.

Anti-Tamper NFC Tag FAQs
How is this tag different from the 26 mm anti-tamper NFC label? +
This model is a 45 × 27 mm rectangular white PET tag with an NTAG213 chip and a published range of up to 1.5 cm. The other model is a 26 mm round brittle-paper label using FM11RF08 with a published range of up to 3 cm.
Can every NFC smartphone read the NTAG213 tag? +
NTAG213 is commonly used with NFC devices, but universal compatibility should not be assumed. Test the intended phones, operating systems, antenna positions, record format and application response.
Why is the published reading range only 1.5 cm? +
The specification gives a reader-dependent free-air value of up to 1.5 cm. Phone antenna design, label orientation, mounting material and nearby components can further change the installed range.
Does removing the PET label make it permanently unreadable? +
The page states that removal changes the antenna and may make the tag ineffective or alter its status. Because these outcomes differ, confirm the actual supplied structure through removal and readback testing.
Does the tag automatically report that a package was opened? +
No. This is a passive NFC tag. It does not send an alert independently. A user or reader must scan it, and the application must interpret the electronic response and database status.
Can the tag be attached directly to metal electronics? +
This model is not published as an on-metal tag. Metal can detune the antenna and prevent reliable interaction. Provide the device construction and available clearance for an anti-metal option review.
What should we verify during pilot testing? +
Verify surface fit, adhesion, artwork, barcode readability, programmed data, phone compatibility, installed read range, partial removal, complete removal and attempted reapplication.
