SRSW16 is a UHF (Ultra High Frequency) silicone wristband designed for personnel identification and management. It adopts the Alien H3 ceramic chip and features long-range reading (up to 6 meters), anti-interference, waterproof and dust-proof (IP67), and comfort and durability, which makes it suitable for a wide range of scenarios that require efficient identification.
1. What is UHF RFID?
UHF RFID (Ultra-High Frequency Radio Frequency Identification) is an automatic identification technology that utilizes the 860~960 MHz frequency band for long-distance wireless identification. It realizes non-contact, batch and fast reading of tag data through radio waves, which is widely used in logistics, retail, asset management, personnel tracking and other fields.
2. UHF RFID works
Label (Tag):
By the chip (stored data) and antenna composition, divided into passive (Passive) and active (Active) two kinds.
Passive tags: rely on the read-write electromagnetic waves emitted by the power supply (no battery), low cost, long life (such as SRSW16 wristbands).
Active tags: built-in batteries, active emission of signals, reading distance is farther (up to 100 meters), but the price is high.
Stored information includes Unique ID (EPC code), user data (such as production date, batch number, etc.).
Read-write (Reader):
Transmits RF signals to activate the tag and receives data returned by the tag.
Supports fixed (e.g., access control, warehouse access) or handheld (e.g., inventory terminals).
Antenna:
Enhance the signal transmission efficiency between reader and tag.
Back-office system:
Process the read data, and ERP, WMS and other systems integration, to achieve intelligent management.
3. Key Features of UHF RFID
| Feature | Description |
|---|---|
| Long Read Range | Passive tags: 3~12 meters, Active tags: up to 50~100 meters. |
| Batch Reading | Capable of reading hundreds of tags per second (e.g., warehouse inventory). |
| Strong Anti-Interference | Works in metal/liquid environments (requires special tag design). |
| Read/Write Capability | Supports multiple data rewrites (e.g., logistics status updates). |
| High Security | Supports encryption protocols (e.g., ISO 18000-6C), anti-counterfeiting. |
4. UHF RFID vs. Other RFID Frequency Bands
| Frequency Band | Range | Read Distance | Typical Applications |
|---|---|---|---|
| LF (Low Freq.) | 125~134 kHz | <10 cm | Animal tracking, access cards (metal/water resistant). |
| HF (High Freq.) | 13.56 MHz | 10 cm~1 m | NFC payments, library management (e.g., transit cards). |
| UHF (Ultra-High Freq.) | 860~960 MHz | 1~12 m | Logistics, retail, personnel tracking (e.g., SRSW16 wristband). |
5. UHF RFID typical application scenarios
5.1 Logistics and supply chain
Warehouse management: batch scanning of goods to improve the efficiency of access to the warehouse (e.g. Jingdong, Amazon smart warehouse).
Freight tracking: container, pallet-level logistics visualization.
5.2 Retail and anti-counterfeiting
Unmanned supermarket: automatic identification of goods for settlement (e.g. Amazon Go).
Luxury goods anti-counterfeiting: tags bound to blockchain to verify authenticity.
5.3 Personnel & Asset Control

Production line traceability: full life cycle tracking of automotive parts.
6. Limitations of UHF RFID
Metal/liquid interference: need to use metal-resistant tags or adjust antenna design.
Privacy controversy: data security issues that may involve personnel tracking (encryption required).
Higher cost than barcode: suitable for high value or frequent read/write scenarios.
7. Core advantages of SRSW16 wristband

8.4 Amusement parks and water parks
Visitor experience optimization
Cashless payment (wristband binding account, consumption direct debit).
Fast pass (VIP channel for project queuing).
Waterproof applicable scenes
Water parks, swimming pools and other wet environments can still be used normally.
