RFID a 125kHz yana aiki kyau a cikin alamomin da aka saka karamin kwalli inda wadannan tsarin UHF na iya kuskurewa. Many factories actually put low frequency tags on tools kept in stainless steel storage racks because they just don't interfere with signals like other technologies might. Car makers have been embedding these LF tags right into metal component bins for years now without any problems whatsoever. Sure, the data transfer isn't super fast – usually around 1 to 2 kilobits per second – but this slower speed actually helps cut down errors when there's all that electromagnetic noise coming from big machines on factory floors. That makes 125kHz RFID especially good for tracking things in tough manufacturing conditions where reliability matters most.
