Our RFID seal one time tag combines a 70 × 20 mm brittle-paper construction with an M4QT UHF chip. It is intended for controlled, single-use sealing workflows in which every applied EPC is assigned to one package, access point or inspection event.
RFID Seal One Time Tag Specifications
Confirm the finished surface, seal position and reader setup before approving the production configuration.
| Specification | Available Configuration | Order Information |
|---|---|---|
| Finished size | 70 × 20 × 0.2 mm | Confirm the usable area around the sealed opening. |
| Antenna size | 22 × 8 mm | Keep the active area clear of folds and sharp edges. |
| RFID chip | M4QT | Provide the EPC and user-memory data plan. |
| Protocol | ISO 18000-6C Gen2 | Confirm compatibility with the selected UHF reader. |
| TID | 96 bits | Define whether the TID will be captured in records. |
| EPC memory | 128 bits | Submit the numbering structure and allocation rules. |
| User memory | 512 bits | Specify the required data and write-lock policy. |
| Reserved memory | 32-bit access and 32-bit kill passwords | Define password ownership and access procedures. |
| Frequency | 860–960 MHz | State the destination market and reader frequency. |
| Face material | Printable brittle paper | Provide artwork and variable-print requirements. |
| Installation | Pressure-sensitive adhesive | Identify the substrate, coating and application method. |
| Reference read range | Up to 50 cm in free-air testing | Validate the applied tag with the production reader. |
Build a Controlled One-Time Sealing Process
The seal should be commissioned, applied, verified and retired as one managed record rather than treated as a reusable inventory label.
Assign
Allocate one EPC to the package, document, device or shipment that will receive the seal.
Apply
Bridge the protected opening with the antenna positioned inside the intended break zone.
Verify
Read the applied seal and match its EPC, printed number and assigned record.
Close
Retire the identifier after authorized opening, damage, rejection or replacement.
Match the Seal Position to the Opening Route
Cartons and Shipping Boxes
Place the seal across the flap and fixed panel so normal opening stresses the brittle paper and antenna.
Product and Medicine Packaging
Confirm available space, surface coating and how the consumer or operator will open the package.
Equipment Access Panels
Apply the label across a cover or service point where removal is expected before internal access.
Document and Evidence Enclosures
Link the printed seal number and EPC to the enclosure record before the item enters custody.
Retail Product Closures
Evaluate handling, shelf exposure and customer opening without claiming the seal prevents every attack.
Reusable Transport Items
Assign a fresh seal to each journey while retaining the carrier or container as a separate reusable asset.
Define Status Rules for Every Seal Event
A useful system distinguishes unused seals, correctly applied seals, authorized openings and unexplained exceptions.
| Seal Status | Typical Trigger | Record Action | Physical Action |
|---|---|---|---|
| Available | Encoded and released for use | Place the EPC in controlled inventory | Keep unused seals protected and counted |
| Applied | Matched to a specific sealed item | Store time, operator and item reference | Inspect adhesion and scan performance |
| In transit | Shipment or custody movement begins | Record required checkpoint reads | Protect the seal from avoidable abrasion |
| Opened | Authorized access breaks the seal | Close the record with opening details | Retain or dispose of the broken seal as required |
| Exception | Damage, mismatch or unexplained removal | Hold the item and create an investigation record | Photograph and isolate the affected seal |
| Replaced | A rejected seal is replaced before release | Link the old and new identifiers | Destroy or quarantine the rejected label |
Test the Applied Seal Before Production
Surface and Removal Test
- Clean and prepare the actual package surface
- Apply with the planned pressure and dwell time
- Test coated, textured and curved substrates
- Open the package through its normal access route
- Inspect paper tearing and antenna damage
RFID Verification Test
- Use the intended handheld or fixed reader
- Check reads before and after application
- Test the approved orientation and distance
- Confirm EPC-to-item record matching
- Record results after authorized opening
Printing, Numbering and RFID Data
We can review the relationship between printed information and electronic data after the numbering rules and data owner are confirmed.

RFID Seal One Time Tag Questions
Why is this RFID seal described as one time? +
The printable brittle-paper structure is intended to tear when removed from a suitable surface. An opened or rejected seal should be retired rather than reapplied to another item.
Does a broken seal always become unreadable? +
The result depends on where and how the label tears. Position the antenna across the intended break path and test the applied construction if loss of RFID response is part of the acceptance requirement.
Is the listed 50 cm read distance guaranteed? +
No. It is a free-air reference. Reader power, antenna orientation, nearby materials, interference and the installed package can change the practical reading distance.
Can it be used directly on metal or liquid packaging? +
Metal, foil and nearby liquids can detune a standard UHF label. Provide the complete package structure and installation position so applied samples can be evaluated.
Can the seal carry batch or shipment information? +
The M4QT configuration lists a 128-bit EPC and 512-bit user memory. Submit the exact data structure so its size, encoding and lock requirements can be checked.
Does the passive UHF seal provide live location tracking? +
No. The passive tag responds when energized by a compatible UHF reader. Location or event history must come from reader checkpoints and the connected software system.
What should be included with a quotation request? +
Please provide the application surface, sealing position, environment, reader model, frequency region, artwork, EPC and user-data requirements, quantity and destination country.
