Standalone card readers are high-security devices suitable for controlling almost any access point. Their major advantage is that, beyond card identification, they can independently control door locks, eliminating the need for a separate door control panel in the system. Their installation and use are extremely simple.
S2-MF is a sleek, standalone, drip-proof card reader with a plastic housing, designed for 13.56 MHz MIFARE cards. Its energy-efficient design ensures long-lasting and cost-effective operation. Master cards make adding or deleting users quick and easy. With an IP66 rating, it's suitable for outdoor use, though it is not vandal-resistant due to its plastic construction.
