Our RFID tamper-evident tag for wine is a 27 mm adhesive NFC label with an ST25TA64K chip and 22 mm antenna. It is designed for bottle and closure applications where an attempted removal should damage the antenna and prevent normal reuse of the tag.
RFID Wine Tamper Tag Specifications
Approve the NFC tag on the completed bottle and closure. Glass, liquid, cap material, foil decoration and tag position can change reading performance compared with an unattached sample.
| Specification | Listed Configuration | Wine Project Check |
|---|---|---|
| Tag diameter | 27 mm | Confirm the available flat area on the closure or bottle. |
| Antenna diameter | 22 mm | Align the antenna with the intended tamper point. |
| NFC chip | ST25TA64K | Confirm the encoded-data and reader requirements. |
| Protocol | ISO 14443A | Test the phones or NFC readers used in the project. |
| Memory structure | TID/UID, user and reserved memory areas | Define the required content before encoding. |
| Operating frequency | 13.0–14.5 MHz | Evaluate performance on the filled bottle. |
| Nominal read range | Up to 1 cm in an interference-free test | Record the reader, orientation and tap position. |
| Face material | Printable coated paper | Confirm artwork and protection requirements. |
| Installation | Adhesive backing | Test adhesion to the selected cap or bottle surface. |
| Tamper behavior | Antenna damage after tearing or removal | Approve the intact and opened NFC responses. |
Memory confirmation: Submit the intended URL, identifier or data structure so chip capacity and encoding can be confirmed before production.
Choose the Correct Position on the Wine Closure
The label must intersect the actual opening or removal path. A tag placed only on a stationary bottle surface may remain intact when the closure is opened.
Across a Cap Seam
Bridge the cap and the adjacent closure surface so normal opening places stress on the tamper antenna.
Under a Shrink Closure
Evaluate the tag position, shrink temperature and pressure to prevent damage before the bottle reaches the customer.
On a Bottle Seal
Ensure the 27 mm tag covers the protected access point without excessive folding, lifting or contact with interfering decoration.
Closure drawings matter: Provide the cap dimensions, opening direction, liner, shrink sleeve and decorative foil details. A placement that works on one wine closure may not create the same tamper response on another.
Account for Glass, Wine and Metallic Decoration
NFC performance is affected by the entire bottle construction. A successful dry-label read does not confirm performance on a filled and decorated bottle.
| Bottle Variable | Potential Effect | Required Test | Buyer Decision |
|---|---|---|---|
| Filled bottle | Liquid can change the NFC reading zone | Read at the intended fill level and tap position | Approve the finished-bottle reading method |
| Metal cap or foil | Conductive material may detune the antenna | Test the exact cap and foil construction | Adjust position or tag construction if required |
| Curved glass | The small label may lift or bend unevenly | Condition applied samples and inspect the edges | Approve the bonding area and application pressure |
| Shrink process | Heat or pressure may damage the inlay prematurely | Run samples through the actual packaging line | Set process limits for tag installation |
| Decorative printing | Ink, coating or foil may alter appearance or reading | Test the final printed and decorated assembly | Approve graphics and NFC performance together |
Test the Tag on the Bottling and Packaging Line
The application process should preserve the antenna before sale while ensuring that the intended opening movement damages it afterward.
Apply
Place the label in the approved orientation using the planned manual or automated process.
Process
Run the bottle through capping, shrink wrapping and handling conditions used in production.
Verify
Read the intact tag at the approved tap point and check the encoded bottle record.
Open
Open the closure normally and inspect antenna damage, visible evidence and NFC behavior.
Production sampling: Include bottles from different points in the labeling run. This helps identify placement variation, incomplete bonding and accidental antenna damage caused by packaging equipment.
Define the Intact and Opened Bottle Results
| Inspection State | Physical Condition | Expected NFC Check | Recommended Action |
|---|---|---|---|
| Before application | Flat tag with no visible damage | Chip and encoded content are readable | Record initial sample results |
| After packaging | Tag remains aligned and fully bonded | Tag reads using the approved method | Accept the unopened bottle |
| After transport simulation | No premature tearing or edge lift | Tag remains readable at the approved point | Confirm package durability |
| After normal opening | Antenna or label shows irreversible damage | Response follows the approved opened condition | Record the bottle as opened |
| Unreadable but visually intact | No obvious evidence of opening | Repeat with the approved device and orientation | Quarantine for controlled inspection |
No-read interpretation: An unreadable tag does not by itself prove that a bottle was opened. Packaging damage, metallic interference, reader position and an incorrectly applied label can produce a similar result.
Wine Data, Printing and Bottle Serialization
We can review the printed design and encoding structure after the bottle identification workflow and available NFC memory are confirmed.
Bottle Identification
- Wine name or product code
- Batch or bottling reference
- Visible serial number
- QR code or barcode
NFC Content
- Product-information URL
- Bottle or package identifier
- Registration or service link
- Defined verification destination
Data Control
- UID and printed-code matching
- Variable-data input format
- Encoding verification method
- Finished data output file
Authentication scope: The NFC tag supplies an electronic identifier and tamper-sensitive antenna. Your website or database must determine whether a bottle record is valid and how duplicate or unexpected scans are handled.

RFID Wine Tamper Tag Questions
Where should the 27 mm tag be placed on a wine bottle? +
The tag should cover or bridge the actual access route, such as a cap seam or protected closure point. Final placement depends on cap construction, opening direction, foil and available bonding area.
Will wine inside the bottle affect the NFC reading? +
Liquid can influence the reading zone. Test the tag on the actual filled bottle with the intended phone or reader instead of relying only on an air test or empty bottle.
Can the tag operate near metal foil or a metal cap? +
Metal and metallic decoration can detune an ordinary NFC antenna. Provide the complete cap and foil structure so positioning or another tag construction can be evaluated with samples.
What happens when the wine tag is removed? +
The antenna is designed to become damaged when the tag is torn or removed, preventing normal reading and intact reuse. The exact result must be approved on the selected bottle closure.
Can customers scan the wine tag with a smartphone? +
Compatible NFC-enabled smartphones may read the ISO 14443A tag. Phone model, settings, bottle construction, tag orientation and encoded content should be included in the user test.
Can each bottle receive different printed and encoded data? +
We can review requirements for logos, QR codes, barcodes, serial numbers and NFC personalization. Supply the source-data format, matching rules and required output records.
What information should we submit for wine bottle samples? +
Please provide the bottle and cap dimensions, closure materials, foil or shrink construction, opening direction, reader model, artwork, encoding requirements, quantity and destination country.
