All You Should Know About EM4305 RFID Coin Tags
RFID technology has revolutionized industries by offering seamless identification, tracking, and transaction solutions. Among its diverse applications, EM4305 RFID Coin Tags stand out as compact, durable, and versatile tools for businesses and organizations. In this blog, we’ll dive deep into what makes these coin-shaped tags unique, their technical advantages, and why they’re increasingly becoming the go-to choice for innovative RFID solutions.
What Are EM4305 RFID Coin Tags?
EM4305 RFID Coin Tags are small, disc-shaped devices embedded with the EM4305 RFID chip—a high-performance, low-frequency (125 kHz) integrated circuit designed for reliable read/write operations. Unlike traditional RFID cards, these coin-shaped tokens combine ruggedness with user-friendly design, making them ideal for applications where durability and portability matter.
Key Components:
-
EM4305 Chip: The core of the tag, featuring 512-bit EEPROM memory for data storage and a unique 32-bit identifier (UID).
-
Antenna: Integrated to enable wireless communication with RFID readers.
-
PVC Housing: Waterproof, heat-resistant, and customizable in size (13mm to 40mm diameters).
Technical Advantages of the EM4305 Chip
The EM4305 chip is engineered for precision and adaptability. Here’s why it’s a standout choice:
| Feature |
EM4305 Benefits |
| Memory Capacity |
512-bit EEPROM for storing unique IDs, access codes, or transaction data. |
| Compatibility |
ISO 11784/11785 compliant; works with FDX-B and reader-talk-first protocols. |
| Durability |
Operates in -40°C to +85°C; resistant to moisture, dust, and physical wear. |
| Security |
32-bit password protection and lockable EEPROM to prevent unauthorized tampering. |
| Versatility |
Supports Manchester/Bi-phase encoding; adjustable data rates (8–64 RF clocks). |
Unlike its sibling EM4205, the EM4305 offers enlarged contact pads for direct coil connections, eliminating the need for additional modules. It also includes a 330pF resonant capacitor option for enhanced frequency tuning.
Top Applications of EM4305 RFID Coin Tags
These tags are not just “coins”—they’re powerful tools across industries:
-
Access Control
Replace keycards with durable coin tags for gyms, offices, or gated communities. Their compact size fits easily on keychains or lanyards.
-
Smart Payments
Deploy them as cashless payment tokens in amusement parks, festivals, or public transport systems.
-
Asset Tracking
Track tools, equipment, or inventory in warehouses using their unique UID and anti-tamper features.
-
Event Management
Use printed RFID coins as souvenir badges or session passes at conferences.
-
Industrial Automation
Integrate with IoT systems for real-time monitoring in manufacturing or logistics.
Why Choose PVC-Based EM4305 RFID Coin Tags?
The PVC housing isn’t just about aesthetics—it’s about performance:
-
Waterproof: Survives outdoor conditions, rain, or accidental spills.
-
Customizable: Gloss/matte finishes, full-color printing, QR codes, or branding.
-
User-Friendly: Tap-to-scan functionality with a read range of 2–6 cm (ID) or 1.5–5 cm (IC).
