LF + HF RFID key fobs are the most common dual-frequency key fobs and usually have an LF and HF antenna.Modern applications often call for multiple chips of different frequency to be contained within a small keyfob. The manufacturing challenge is to embeed the chips and antennas in such a small space that RF signals will not interfere with one another while still maintaining minimal chip and antenna blemish. we excels in engineering bespoke solutions for any conceivable combination of two or three chips in a single keyfob.
