About this item

• WIDE SYSTEM COMPATIBILITY SUPPORT: Operating at 125KHz, these rfid key fob cards follow EM4100 and TK4100 protocols, allowing seamless integration with most existing access control panels, time attendance terminals, and standalone readers so you can expand or upgrade your system without replacing hardware, ideal for installers and facility managers planning scalable deployments.
• TOUGH WEATHERPROOF BUILD QUALITY: Each rfid key fob uses a sealed ABS housing that resists splashes, dust, and daily bumps, so your access credentials stay readable in parking lots, entry gates, gyms, and other demanding spots, ideal for users who need reliable tags that keep working wherever the day takes them.
• EFFORTLESS EVERYDAY CARRY CONVENIENCE: Slim, featherlight rfid key fob design clips quickly onto your keys, lanyard, or badge reel so access is always at your fingertips, and simple proximity scanning keeps entry lines moving smoothly for busy users managing multiple doors.
• TAMPER-RESISTANT ACCESS CONTROL: Pre-programmed, read-only rfid key fob cards store fixed ID data that cannot be altered, helping prevent unauthorized cloning or accidental re-encoding and giving your door entry system a stable, predictable credential for everyday use in shared workplaces or rental properties.
