The lock uses a 13.56MHz M1 card, which is more sensitive than ordinary 125kHz ID cards. Sensing Thickness: Cards can penetrate thicker wooden boards (up to 38 mm/1.5 inches), perfect for home cabinets, lockers, drawers, cupboards, wardrobes, data racks, storage boxes, secure gyms, swimming pools, libraries, factories, and offices, etc., with a wide range of applications.

For IOS, add a new transit card to the wallet and then program the transit card into your lock as an nfc access card. Robust Mechanism and DIY Installation: The latch and mortise are made of metal. They are strong enough to lock. Easy to install with screws without drilling. For any non-wood surfaces, it is recommended to use tape instead of screws for installation.
