How to use the hotel room card

At present, there are three kinds of hotel room cards, one is magnetic stripe card, the other is contact ic card, and the other is inductive room card.

The first type of door lock magnetic card generally indicates the card insertion direction on the magnetic stripe card. Press the arrow and insert it into the slot of the door lock to open the door. Because the magnetic stripe door card is easy to degauss, it often leads to the inability of guests to open the door when swiping the card, which brings bad housing experience to guests, so it has gradually been eliminated by the market.

Followed by contact IC room card, this room card chip is generally outside the surface of PVC card, and there will be an arrow mark on the card surface to indicate the card insertion direction. Just insert the card slot on the door lock as indicated by the arrow and hear the sound of the door lock turning, and you can open the door. This kind of room card needs to contact the chip with the door lock reader to read the card and open the door. After repeated use, the chip on the card will be damaged or fall off, so it is no longer used gradually.

The third type is the current popular inductive room card, which consists of a chip and an inductive antenna (coil) and is packaged in a standard PVC card without any exposed parts of the chip and antenna. Reading and writing operations are mainly completed according to Faraday electromagnetic induction principle, and only the induction area near the door lock can open the door.
