What kinds of key cards are there for hotel locks?

Hotel lock card is a tool to unlock hotel inductive lock, which can be roughly divided into five categories: magnetic card, ic card, TM card, Temic card and inductive ID card. Different types of door cards have their own characteristics. In daily life, we should not only consider the type of door lock, but also consider the safety, quality, quality, function, brand and other issues. Let's take a look with Bian Xiao. What kinds of key cards are there for hotel locks?

1, magnetic card

The principle of magnetic card is to magnetize the magnetic particles on the magnetic card through the recording head. Magnetization of the magnetic card will leave the same magnetism as that of the current, and then the magnetic card will record the information sent by the current. Magnetic cards are low in cost and easy to read and write, but they are also easy to lose magnetism. It is the earliest smart card used for hotel door locks. Even now, some small hotels are still in use, but they are on the verge of elimination.

2.IC card

IC card is an integrated circuit chip embedded in a fixed position on the "substrate" and can read and write electronic information. IC cards have a long history and are characterized by being afraid of water and dust, but they are cheap. IC cards can be divided into contact type and non-contact type. After the card is inserted into the card holder, it exchanges information with the outside through the contact piece with circuit pins outside the plastic card. However, the ic card commonly used in the hotel lock industry today is non-contact.

3.TM card

TM card is the abbreviation of TouchMemory, also called IB card. TM card has both the operability of non-contact IC card and the cheapness of contact IC card, and it is one of the most cost-effective IC cards at present. Each TM card has a globally unique serial number and cannot be copied. TM card is encapsulated in stainless steel and can store encrypted information. TM card itself is a microcomputer chip. Due to the stainless steel package, the appearance is similar to that of button cell. It is not afraid of water, magnetic field and dust. Suitable for schools, rental houses, sauna cabinets, hotels and other occasions.

4. Inductive ID card

Cards can only be read but not written, which is the biggest difference from IC cards. It has the only ID code in the world, also called identification card, and its working frequency is 125KHZ, which is suitable for rental houses, families, office buildings, high-grade houses, villas and other places.

5.Temic card

TEMIC card is a low-cost, readable and writable RF IC card, which only controls the writing operation by encryption. The working frequency of TEMIC card is 125KHZ. Because the power supply and reading and writing operations of the card are completed by radio waves, it is not in contact with the card reader, so it is convenient to use and overcomes the shortcomings of contact IC cards such as water, dust and easy damage. Temic card is characterized by non-contact operation, so the system has high stability, long service life and convenient use. Temic card has low cost and low cost of card reading module, which is widely used in hotel intelligent door lock system, and is suitable for hotels, apartments, government agencies, guest houses and other places.

How to choose the right hotel door lock?

1, gatekeeper card type

At present, there are inductive door locks in the market with IC card, TM card, Temic card, inductive ID card and magnetic card as the opening mode. The hotel only needs to choose the most suitable inductive door lock according to its own characteristics.

2. Look at the security guard.

Users should examine the safety of hotel inductive door locks from the structural design of the locks. Because the door lock is unsafe, the mechanical structure design plays a very key role, especially the lock core technology and clutch motor technology.

Step 3 look at stability

The induction door lock of the hotel is driven by a motor, so it is easy to have an accident if it is unstable. Usually, there are several main factors that affect the stability of hotel inductive door locks. One is the stability of mechanical structure, especially the mechanical structure of lock core and clutch structure. The second is the stability of the motor working state, mainly to investigate whether the special motor for door lock is used. The third is the stability and anti-interference of logic circuit, mainly to investigate whether there is a protection circuit design.

Step 4 look at the quality

The material and manufacturing process of hotel induction door lock determine the quality and service life of the door lock. The service life of locks made of different materials is different, and different surface treatments have great influence on the service life of locks. For seaside hotels or outdoor hotels, the locks used must have strong corrosion resistance, and the circuit board must be treated with anti-corrosion, the lock core must be treated with anti-corrosion surface, and the lock surface must be treated with anti-corrosion and anti-ultraviolet.

5, look at the function

For a hotel, guest room management should conform to the standard management of the hotel, and the management function of door lock should not only be convenient for guests, but also improve the overall management level of the hotel. Therefore, it is best for electronic door locks to have perfect hotel management functions.

6. Look at the brand

Big brands often have guaranteed product quality, good after-sales service, mature production technology, reasonable price positioning and strict state supervision. Consumers can choose the appropriate hotel induction lock according to their actual needs.
