Development history of hotel key cards
Tourism and business activities have existed since ancient times, and hotels have emerged as the times require. The hotel door locks used in early-phase hotels are mechanical locks, which are no different from home locks. They are also equipped with mechanical keys, mainly made of copper, but also made of other metals. Rooms are usually identified by sticking a label with the room number on the key.
In the 1970s, a singer named Connie Francis was attacked in her hotel room. After this event, Tor Sørnes, an inventor from Norway, was inspired to invent a more secure hotel door lock. And then launch the recordable keycard lock without a hole card, it is the systems in hotels use that allow each hotel guest can have their unique key.
The emergence of this system has laid the foundation for the hotel key card, and also means the hotel key card is available. After years of development, hotel smart card basic technology has gone through three stages: magstripe card, IC card, and RFID card, and widely used in our lives.
The evolution and development of smart cards have also enriched the related technologies of hotel smart locks and promoted the updating of access control technology in the field of hotel locks.
Common types of hotel key cards.
The RFID Hotel Key Cards
The principle of the RFID key hotel card is wireless communication technology, which use radio wave to communicate with other intelligent devices, and can identify specific targets and read-and-write related data through radio signals. And it is no need to establish mechanical or optical contact between the identification system and specific targets.
RFID key hotel cards generally allow the holder access to facilities in the hotel by a card, such as taking the elevator, opening the room door, entering the public areas in the hotel, etc., which realize a card with multiple purposes.
And you can set your need card by the guest access management system and key card encoder. The RFID card has stable performance, mature technology, high security, and large memory capacity. It is one of the most widely used room cards in the hotel industry.
Magnetic Hotel Key Cards
The principle of the magnetic stripe card is that the liquid magnetic material or magnetic strips is used as the information carrier, and the liquid magnetic material is coated on the plastic card.
Magnetic stripe cards are generally used as identification cards, use with the magnetic reader, which can write, store, and rewrite information. Magnetic cards have low cost and are easy to read and write, but are also prone to abrasion and loss of magnetism.
Magnetic cards are also the earliest smart cards used in hotel locks. Even now, some small hotels are still using them, but they are on the verge of being eliminated.
How do hotel key cards work?
There are three main types of famous hotel room cards in the current hotel industry, magnetic stripe cards, contact IC cards, and inductive cards. Usually, the user access method will be indicated on the back of the hotel room card for the convenience of guests.
The first type of magnetic stripe card, this type of card will be marked with the card insertion direction. Inserted it into the card slot of the door lock to open the door.
But you need to pay attention to is that the magnetic card is easy to demagnetize, which often leads to the guests not being able to open the door when swiping the card, thus bringing a bad housing experience to the guests. So it has been gradually eliminated from the market.
The second type of contact IC card, the chip of this room card is generally placed on the surface of the PVC card. And there will also be an arrow mark on the surface of the card, indicating the card insertion direction.
You just need to follow the arrow direction to insert the card slot on the door lock, when you listen to the sound of the door lock turning, you can open the door.
This kind of room card completes the card reading and opening action through the contact between the chip and the door lock reader. After repeated use, the chip on the card will be damaged or fall off, so it is also gradually ceased to be used.
The third type is the current popular inductive access control card, which is composed of a chip and an inductive antenna (coil). All parts are packaged in a standard PVC card, and the chip and antenna do not have any exposure.
It is mainly based on the Faraday electromagnetic induction principle to complete the read-and-write operations. When the card reader recognizes the signal sent from the card, it will recognize the card, which can be used to open the door, read unlock records, etc.

Modern electronic room cards can avoid these risks well. Guests only need to tell the front desk staff that the room card is lost.
The hotel staff can report the lost card and make a new room card through the hotel’s secure access control system, which is no need to worry about someone picking up the lost key, resulting in security issues.
On the other hand, the mechanical key cannot read any door opening records, but the room card can. Not only the room card but the card door lock can be checked their unlocking records by the modern hotel access management system backstage.
