Compact Dual-Protocol Sticker with 2-Kbit User Memory
Our UHF dual frequency resistant sticker combines ISO 14443A and ISO 18000-6C Gen2 operation through a Qstar-6SSB chip. Its 60 × 28 × 0.2 mm adhesive format offers a smaller footprint than the 110 × 40 mm EM4423 sticker while providing 2 kbits of published user memory.
The printable coated-paper face supports visible product data, and the tamper-proof construction is intended to prevent intact label transfer. Before procurement, buyers should confirm the expected UHF range because the target page publishes only 1.5 cm in free air despite describing long-range UHF applications elsewhere.

Three Reasons to Evaluate This Qstar-6SSB Model
Smaller Label Footprint
The 60 × 28 mm format requires less package space than the 110 × 40 mm EM4423 sticker. It may suit smaller cartons, product labels and compact non-metal assets where both protocols are required.
Larger User-Memory Capacity
The published 2-kbit user bank can accommodate more structured project data than the smaller user-memory options listed for several adjacent dual-frequency models. The actual allocation must be confirmed before encoding.
Two Reader Ecosystems
ISO 14443A supports close-range interaction, while ISO 18000-6C Gen2 supports UHF communication. Each interface requires compatible hardware and a clearly defined role in the operating workflow.
Verify the Read-Distance Requirement First
| Required Task | Likely Interface | Distance Question | Procurement Action |
|---|---|---|---|
| Close-range product check | ISO 14443A | Must a phone or reader touch or approach the label? | Test all intended phones or close-range readers. |
| Handheld item identification | UHF | What minimum installed range is acceptable? | Measure samples on real products with the final handheld. |
| Shelf or cabinet reading | UHF | How much read-zone separation is required? | Test tag density, orientation and unwanted reads. |
| Warehouse portal reading | UHF | Are metres of reliable range required? | Do not approve this model without a successful portal trial. |
| Consumer information access | ISO 14443A | Which phones and application will be used? | Confirm device support, record format and response. |
If long UHF range is mandatory, compare the larger EM4423 dual-frequency sticker, whose specification table publishes up to 8 metres in free air.
Plan the Shared Memory Before Encoding
Define the Data Map
The block memory is shared with the UHF user bank. Buyers should provide a field-by-field data plan rather than treating the published capacities as completely independent storage areas.
- UID or TID database field
- 96-bit EPC structure
- User-memory field locations
- Read and write permissions
- Locking or password requirements
Define Interface Visibility
Specify which information must be available through ISO 14443A and which information the UHF reader must capture. Avoid storing confidential business data without an approved access-control design.
- Close-range user interaction
- UHF operational data
- Public and restricted fields
- Invalid-item response
- Retired or removed-label status
RFID memory does not establish authenticity by itself. A connected application must compare the captured identity and status with an authorized database record.
Mounting Conditions That Require Sample Tests
Metal Proximity
Direct metal contact may detune either interface. Review our UHF anti-metal tags for metal assets.
Liquids and Dense Products
Test the label on filled containers or complete products because contents can affect the UHF read zone and close-range interaction.
Coated-Paper Exposure
The standard face is printable coated paper. State any exposure to water, UV, abrasion, cleaning agents, oil or outdoor weather so the finished construction can be reviewed.
Confirm the Anti-Transfer Result on Real Surfaces
| Test Condition | Physical Check | ISO 14443A Check | UHF Check |
|---|---|---|---|
| Intact installation | Inspect bonding and edge contact. | Confirm the expected close-range response. | Record the installed read distance. |
| Edge lifting | Identify the first visible structural change. | Check whether the interface still responds. | Check whether range or readability changes. |
| Partial removal | Inspect antenna and adhesive damage. | Retest with the approved device. | Retest with the original reader settings. |
| Complete removal | Check whether intact transfer is possible. | Confirm the final electronic state. | Confirm the final electronic state. |
| Reapplication attempt | Check visible evidence and renewed adhesion. | Verify whether the original interaction remains. | Verify whether the original identity remains readable. |
A passive sticker does not independently transmit a removal alarm. A reader must interrogate the tag, and the connected application must interpret a missing, damaged or invalid response.
Printing and Variable Data Preparation
Visible Artwork
Provide the logo, fixed text, colour, barcode or QR code, serial format and orientation. All readable information must fit within the 60 × 28 mm finished size.
RFID Encoding
Provide the EPC sequence, user-memory content, close-range record requirements and any access-control instructions. Identify the required format for encoded-data output.
Identity Matching
Define how the printed serial, barcode, UID or TID and EPC relate to the same item. Approve sample records before authorizing the production data set.
Sample Approval Workflow
Confirm the Reader Task
Define the required distance and information for each protocol before selecting the model.
Apply to Real Products
Use the actual surface, contents and intended 60 × 28 mm label position.
Verify Data and Range
Read the approved fields and record installed performance through both interfaces.
Test Label Transfer
Retest both interfaces after lifting, partial peeling, removal and reapplication.

UHF Dual Frequency Resistant Sticker FAQs
Is the published reading range 1.5 cm or 1.5 metres? +
The target specification states 1.5 cm in free air. Because this conflicts with the page's general long-range claims, treat the required distance as an item to confirm through samples rather than assuming the value means 1.5 metres.
Can both protocols be read by the same device? +
Only a device specifically equipped for both ISO 14443A and ISO 18000-6C Gen2 can access both. Standard phones and close-range readers do not normally replace a dedicated UHF reader.
Can every NFC smartphone read the sticker? +
Compatibility should be tested with the intended phone models, operating systems, application and record format. Support for the frequency alone does not guarantee the required user interaction.
Can the 2-kbit user memory hold product records? +
It can store project-defined data within the available capacity, but the target specification states that block memory is shared with the UHF user bank. Submit the complete data map so available space and interface access can be confirmed.
Is this sticker suitable for metal or liquid containers? +
No on-metal or liquid-container performance is published for this model. Metal and liquids can change RFID performance, so the complete filled product must be included in sample testing.
Does removing the sticker automatically trigger an alert? +
No. This is a passive RFID sticker. A reader must interrogate it, and the software must recognize a missing or changed response. The physical failure of both interfaces should be confirmed through removal testing.
What should we verify before approving production? +
Verify the surface fit, installed read ranges, phone and reader compatibility, memory allocation, printed-to-RFID mapping, adhesion, partial-removal response, complete removal and attempted reapplication.
