Compatible low-frequency cards include EM4100, EM4305, T5557, T5577, TEMIC, and standard ID cards. High-frequency compatible cards include M1 (Mifare) and other 13.56MHz induction cards.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this switch be used with both 110V and 220V electrical systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This is a wide-voltage switch designed to work with AC 110V and AC 220V systems, making it suitable for hotels and properties in virtually any country. DC 5V and 12V configurations are also available, and custom voltages can be arranged.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How is this hotel key card switch installed?\u003c\/h4\u003e\n\u003cp\u003eA: The switch uses standard 86mm × 86mm wall box mounting with left\/right installation — the same as most standard wall switches. The ultra-slim 29mm bottom box height makes it easy to fit into existing wall boxes without modification in most cases.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens when a guest removes their key card from the slot?\u003c\/h4\u003e\n\u003cp\u003eA: When the key card is removed from the card slot, the switch initiates an automatic power-off sequence after a brief 10–15 second delay. This cuts power to all connected room devices, including lights, air conditioning, and the TV, ensuring no energy is wasted after the guest leaves.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this switch available in different load capacities and colors?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
