FAQ

1. What is the difference between EM4305 and EM4205?
Both chips share the same architecture and operate at a frequency of 134.2 kHz. The EM4305 typically offers more memory and extended functions, while the EM4205 is designed for cost-sensitive applications with slightly simplified features.

2. Can EM4305 cards work with 125 kHz readers?
No. Although both are low-frequency RFID chips, the EM4305 operates at 134.2 kHz, which differs from the standard 125 kHz frequency used in EM4100-series cards. Compatibility depends on the reader’s frequency range and supported protocols.

3. Are EM4305 cards rewritable?
Yes. Unlike EM4100-series read-only cards, EM4305 supports read/write functionality. Users can update data such as ID numbers, counters, or timestamps through compatible encoders.

4. What materials are available for EM4305 cards?
DCCO Tech provides EM4305 cards in PVC, PET, PET-G, and PC materials. These options enable users to strike a balance between durability, print quality, and cost, depending on their specific application.

5. What are the typical applications of EM4305 RFID cards?
EM4305 cards are used in access control, animal identification, membership systems, and transportation cards. Their reliable performance and read/write capability make them ideal for both static and updatable ID systems.
