Frequently Asked Questions

Is this RFID tag programmable or rewritable?

No, this is a read-only tag. It comes from the factory with a unique, permanent 32-bit identification code burned into the K4100-compatible chip. The ID cannot be changed, erased, or reprogrammed, which provides a secure and tamper-proof method for object identification.

What readers are compatible with this 125KHz coin tag?

This tag is compatible with any 125KHz RFID reader that supports the EM4100 or K4100 protocol. This includes a wide range of industrial, access control, and hobbyist modules. Ensure your reader is configured for 125KHz operation and EM4100 data format to read the tag's unique ID successfully.

How is the tag mounted and what is its environmental rating?

The tag includes a 3M double-sided adhesive backing for permanent surface mounting. The PVC housing is epoxy-encapsulated and ultrasonically welded, providing resistance to moisture, dust, and corrosion. It is rated for operation in temperatures from -20°C to 85°C, making it suitable for both indoor and harsh industrial environments.

What is the typical read range for this tag?

The read range is highly dependent on the power and antenna design of the reader. Under typical conditions with a standard 125KHz reader, the effective read distance ranges from approximately 2.5 cm to a maximum of 10 cm. For optimal performance, ensure proper alignment between the tag and reader antenna.
