One, the principle of card reading for hotel door locks
A card-operated door lock is an electronic lock that uses infrared sensors to sense and unlock. It is widely used in smart access control systems for hotels, resorts, and clubs, and is primarily divided into RF door locks and inductive lock systems.
The card reader lock sensor contains an internal coil that generates vibration when energized, similar to the primary coil of a transformer. The card itself also contains a coil, which functions like the secondary coil of the transformer. When the two coils are close, they generate current through coupling, providing power to the card. The coupler then sends a query signal, and the card responds, enabling the door to open if the conditions are met.
Second, what types of hotel room keys are available?
1、Inductive room card
Induction-based room cards are the most commonly used type in hotels, as they open doors by touching the sensor area on the door. This method is both safe and convenient.
2、Non-inductive room card
Non-contact door cards operate by inserting the card into a slot to unlock the door. These cards are less convenient than direct contact cards and offer lower security.
3、Hotel IC cards
IC cards, also known as integrated circuit cards, have a large capacity and can be encrypted, significantly improving security compared to inductive and non-inductive access cards.
4、Hotel ID cards
Hotel ID cards, also known as identification cards, have fixed internal information, offering secure and convenient use. They are commonly used in various high-end and large-scale hotels.
