FAQ

1. What is the main difference between EM4450 and EM4550?
The EM4550 is an enhanced version of the EM4450, offering the same operating frequency and protocol compatibility, but with an extended memory capacity and advanced data protection features for higher-security applications.

2. Are EM4450/EM4550 cards compatible with standard 125 KHz RFID readers?
Yes. These chips are fully compatible with most 125 KHz RFID readers and encoders that support Manchester, Biphase, or PSK data coding formats.

3. Can the cards be printed using regular ID card printers?
Absolutely. DCCO Tech EM4450/EM4550 blank cards are full-panel printable and work perfectly with dye-sublimation and retransfer printers for on-demand personalization and branding.

4. What materials are available for these cards?
You can choose from PVC, PET, PET-G, or PC materials depending on your usage environment. PET-G and PC options are recommended for applications requiring higher durability or temperature resistance.

5. Can DCCO Tech provide pre-encoded or custom-printed cards?
Yes. We offer custom encoding services, printing with your design or logo, and chip pre-programming according to your system requirements.
