Frequently Asked Questions

Are these RFID tags reprogrammable?

No, these tags are not reprogrammable. Each tag contains an EM4305 chip with a factory-programmed, unique 32-bit identification number that is permanently locked and cannot be altered. They are designed for permanent identification.

What type of RFID reader do I need for these tags?

You require a standard 125KHz low-frequency RFID reader. These tags are compatible with most common 125KHz access control readers, duplicators, and ID systems. Ensure your reader supports the EM4305 chip format or Generic 125KHz tag protocols.

What is the effective read range for these tags?

The read range depends on the power and antenna design of your RFID reader. Typical read range for passive 125KHz tags like these is between 5 to 10 cm. For optimal performance, position the tag parallel and close to the reader's antenna coil.

Can these tags be used for cloning or copying access cards?

Yes, these blank tags are commonly used with 125KHz RFID duplicators to copy the ID number from an existing access card, district card, or parking tag onto a new physical key fob. They are designed for this purpose, but always ensure compliance with local security policies.
