All You Should Know About EM4305 RFID Coin Tags

RFID technology allows us to easily identify and track merchandise equipment or security patrols, and makes payments safer and faster. This technology has been integrated into every aspect of our lives and has revolutionized the way various industries operate.

 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?

The EM4305 RFID Coin Tag is a small disc with the EM4305 chip embedded in it. This chip operates at a low frequency (125 kHz), has very stable performance, and is designed to make reading and writing information reliable. Compared with ordinary RFID tags, this coin-shaped tag is more rugged and easier to install, making it ideal for applications that require long-term durability and rugged security.

Key Components:

• EM4305 Chip: The EM4305 chip is the ‘heart’ of the tag. It can store information, has 512 bits of storage space, and also has a unique 32-bit number, making each tag special.

• Antenna: Integrated with the antenna, the tag can transmit and receive information with the RFID reader without the connection of data cables or other devices, thus realizing wireless communication.

• 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:

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:

1. Access Control
   Replace keycards with durable coin tags for gyms, offices, or gated communities. Their compact size fits easily on keychains or lanyards.

2. Smart Payments
   Deploy them as cashless payment tokens in amusement parks, festivals, or public transport systems.

3. Asset Tracking
   Track tools, equipment, or inventory in warehouses using their unique UID and anti-tamper features.

4. Event Management
   Use printed RFID coins as souvenir badges or session passes at conferences.

5. 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).
