Dualfrequency identification token: 125kHz and 13.56MHz, 18mm Key benefits Dualfrequency compatibility lets a single token work with both lowfrequency 125kHz systems and frequency 13.56MHz systems, reducing the need to carry or manage separate tags. Compact 18mm size fits tight spaces and small form factor applications while remaining easy to handle and attach. Straightforward integration for environments that require crosssystem identification, minimizing installation complexity and inventory overhead. Core attributes Frequencies: 125kHz and 13.56MHz for broad reader compatibility. Size: 18mm diameter for compact mounting and discreet use. Function: Identification and contactless communication with compatible readers operating at the listed frequencies. Compatibility: Works with readers and equipment that support 125kHz lowfrequency transponders and 13.56MHz frequency NFC or RFID interfaces. Practical advantages Simplifies deployments where devices or doors use different frequency technologies by providing a single token that covers both ranges. Small footprint makes it suitable for integration into keyrings, tags, housings, and small devices. Reduces logistics complexity when managing mixedfrequency systems in one facility. Typical use scenarios Access control: Use as an identification token for doors, turnstiles, or entry systems that support 125kHz and 13.56MHz readers. Asset tracking and inventory: Attach to equipment or tags where readers in different areas or departments operate on different frequencies. Attendance and locker systems: Provide a compact token for staff or members to present to either LF or HF readers for identification or locker access. Installation and handling tips Place the token where it can be easily presented to the reader surface; test read range and orientation with your specific reader models. Keep away from dense metal surfaces that can interfere with read performance; use appropriate spacers or nonmetallic mounts if needed. Verify reader compatibility with both 125kHz and 13.56MHz protocols in your environment before largescale deployment. This product is intended for applications that require a compact, dualfrequency identification token. Confirm compatibility with your existing reader hardware and application requirements prior to .
