UHF RFID Fragile Labels
Four distinct anti-tamper designs — full‑fragile, bridge‑cut, half‑fragile, and transferable — engineered for asset security, product authentication, and supply‑chain protection. When removal is attempted, the RFID antenna fractures immediately, destroying read capability and ensuring tamper‑evidence.

Product Overview
RFIDSU's UHF RFID Fragile Labels are engineered for irreversible tamper‑evidence with four distinct anti‑tamper technologies:
1. Full‑Fragile: Complete antenna breakage on removal (⭐⭐⭐⭐⭐ Highest security, High cost, Not reusable)
2. Partial‑Fragile: Localized break area on removal (⭐⭐⭐⭐ High security, Medium cost, Limited reuse)
3. Bridge‑Fragile: Bridge‑circuit breaks while antenna remains intact (⭐⭐⭐⭐⭐ Highest security, High cost, Not reusable)
4. Transferable: Can be moved for temporary tracking (⭐⭐⭐ Medium security, Low cost, Reusable)
Unlike conventional RFID labels, these incorporate precise die‑cut break lines that cause the antenna to fracture on removal, immediately destroying read capability and making the tag physically unusable.
Ideal for high‑value asset tracking, pharmaceutical authentication, electronic device sealing, and supply‑chain security where unauthorized removal must be detected and prevented.

Frequently Asked Questions
What's the difference between the four tamper‑proof types?
Full‑fragile: entire label tears apart when peeled; antenna completely severed.
Bridge‑cut: narrow conductive bridge severs; antenna circuit broken but label may stay intact.
Half‑fragile: partial antenna destruction; label remains partially readable but visibly damaged.
Transferable: antenna breaks, adhesive layer stays intact — allows forensic transfer to another surface.
Can the label be removed without breaking the antenna?
No. The die‑cut break lines are designed to fracture the aluminum antenna when any peeling force is applied. The break force is calibrated to ensure tamper‑evidence while allowing normal handling during application.
What surfaces can these labels be applied to?
Most smooth, clean, non‑porous surfaces: metal, glass, plastic, painted surfaces, coated cardboard. Surface preparation (cleaning, degreasing) is recommended for optimal adhesion.
How do I verify tampering has occurred?
Two methods: 1) Visual inspection — the label shows visible cracks/separation. 2) RFID reading — the broken antenna prevents the chip from responding to a reader. Both signals indicate attempted removal.
Can I print variable data on these labels?
Yes. The top surface is thermal‑transfer printable. You can print serial numbers, barcodes, QR codes, dates, etc. using standard label printers (3‑inch core). Pre‑printing service is also available.
