These RFID Key Fobs are categorized by the frequency band in which it operates. Low, High or Ultra-high frequency

Modern key fobs operate through RFID, a smart barcode system that utilizes electromagnetic fields to locate and monitor data on “tags” containing the stored data. Radio waves are used to pass the data.

Due to their ease of use and management, key fobs are commonly accepted. They eliminate the wiggling process of a metal key in a lock – all you need to do is hold or wave the fob over the reader.

Key fobs give the same feature as traditional keys but provide added safety and security. If a fob is lost or you want to deny someone (say, a former employee or tenant) entry, access to that specific fob can readily be cancelled.
