In modern life, smart devices are everywhere, bringing great convenience to our lives. I wonder if you have noticed that when we walk into office buildings, residential areas, or use some smart devices, we often use a small card. Just swipe or touch it, the door will open automatically, and the device can quickly identify the identity. This is TM Card. But do you understand it? What kind of magic does it have that can occupy a place among many smart identification methods? Today, let us unveil the mystery of TM Card and explore its secrets.
What is TM Card?
TM Card, namely Touch Memory Card, is a patented product of DALLAS in the United States. Its birth has brought a new revolution to the field of smart cards. From the appearance, TM Card looks like a button battery, small and exquisite, with a diameter of usually about 16mm and a thickness of only a few millimeters. This size makes it easy to embed it on various objects such as cards, key chains, rings, etc., and it is easy to carry. For example, some of our common community access control key chains may have built-in TM Cards.
In terms of communication, TM Card uses single-line protocol communication, which is a significant feature that distinguishes it from other smart cards. Data can be read and written by instant touch, without the need to insert a card reader for long-term data transmission like traditional contact IC cards, nor does it need to maintain stable signal transmission within a certain distance like contactless IC cards. This unique communication method has the ease of operation of contactless IC cards, which can be completed with a light touch, and the cheapness of contact IC cards, which is relatively low in cost. It can be said that it has the advantages of both and is one of the most cost-effective IC cards at present.
Unique Structure and Characteristics of TM Card
Rugged and durable shell
The reason why TM Card can work stably in various complex environments is due to its sturdy and durable shell. Its integrated circuit chip is sealed in a stainless steel shell, which is like a layer of sturdy armor, giving TM Card excellent characteristics such as waterproof, shockproof, and anti-corrosion. Whether in a humid seaside environment, in an industrial site with frequent vibrations, or a place with corrosive chemicals, TM Card can work normally. For example, in some industrial scenarios where equipment needs to be inspected regularly, workers will use inspection equipment with a TM Card. Even if the equipment is frequently moved and collided in harsh environments, TM Card can ensure the safe storage and accurate reading of data, providing reliable protection for the normal operation of the equipment.
Passive power supply and data reading
Unlike many smart cards that need to carry their power supply, TM Card is a passive device that relies on the power supply of the reader to read information. When the TM Card contacts the reader, the reader provides it with a short period of power, so that the TM Card can be activated instantly and complete the data reading and writing operations. This power supply method not only makes the structure of the TM Card simpler, reduces the problems of increased volume, increased weight and battery aging caused by the built-in battery, but also improves its convenience and stability. Because there is no need to worry about the card being unusable due to insufficient battery power, as long as there is a suitable reader, the TM Card can be operated at any time. For example, in some access control systems, users only need to bring the key fob with the TM Card close to the access control card reader to instantly complete identity recognition and door opening operations. The whole process is fast and stable.
Unique code and ultra-high security
Each TM Card has a built-in laser-engraved 64-bit binary code, which is its unique “ID card”. The total number of codes can reach 280 trillion. Such a huge number of codes can almost guarantee that the code of each TM Card is unique in the world, and the mutual opening rate is zero. In addition, the TM Card chip has an electrostatic protection function, which can effectively prevent external static electricity from damaging the chip, further ensuring the security of the data. At the same time, due to the uniqueness of its code and the special design of the chip, the TM Card is almost impossible to be copied, which makes it widely used in fields with extremely high security requirements. Important places such as bank vaults, military arsenals, and banknote printing plants often use TM Card as an access key to ensure that only authorized personnel can enter, greatly improving the security of the place.
Wide Application Fields of TM Card
Smart security field
In the field of smart security, TM Card can be seen everywhere. In the smart community access control system, the owner only needs to carry an access card embedded with a TM Card, approach the access control card reader and touch it lightly, and the system can quickly identify the identity and automatically open the door. This method is not only convenient and fast, but also greatly improves the security of the community. Traditional access control systems may have problems such as easy password leakage and easy key loss, but the uniqueness and high security of TM Card effectively avoid these hidden dangers. Even if the access control card is accidentally lost, others cannot copy it and use it, because each TM Card has a unique code, and the access control system will strictly authenticate it, and only legitimate users can pass the access control.
Similarly, in the hotel door lock system, TM Card also plays an important role. When guests check in, the hotel will provide them with a room card with a TM Card. Guests can easily open the door and enter the room by touching the door lock with the room card. Compared with the traditional key opening, this method is more convenient and efficient, and it also improves the management efficiency of the hotel. Hotel managers can authorize and manage room cards through the system, set the validity period of room cards, rooms that can be opened, and other information. When the guest checks out, the hotel only needs to cancel the room card’s permissions in the system, and the room card can no longer open the room door lock, ensuring the safety of the guest room.
Public Utilities
In the public utilities field, TM Card also plays an indispensable role. In the power inspection system, staff will use inspection equipment with the TM Card. When the inspectors arrive at the inspection point of the power equipment, they touch the TM Card information button on the equipment with the inspection equipment, and the equipment will automatically record the arrival time of the inspectors, the equipment operating status and other data. These data will be uploaded to the background management system in real time, and managers can monitor and analyze the inspection situation through the system to timely discover equipment failures and safety hazards. For example, through the analysis of historical inspection data, managers can find that the temperature of a certain transformer continues to rise over some time, to arrange maintenance personnel to inspect and repair it in time, avoiding the occurrence of equipment failure.
In the fire inspection system, TM Card also plays a key role. TM Card information buttons will be installed on fire-fighting facilities. Inspectors read the data in the information buttons through the inspection equipment and record the inspection of fire-fighting facilities, including whether the facilities are intact and whether maintenance is required. This helps to ensure that the fire-fighting facilities are in good operating condition at all times and can function normally when a fire occurs. At the same time, through the management and analysis of inspection data, the fire department can optimize the maintenance and management of fire-fighting facilities and improve the level of fire safety management.
In addition, TM Card has also been widely used in metering equipment such as water meters, electricity meters, and gas meters. Taking smart water meters as an example, users use water cards with TM Cards to purchase and measure water. When the water card is inserted into the water meter, the water meter will read the data in the card, record the user’s water consumption, and deduct fees based on the user’s water purchase volume. This method realizes the intelligent management of water use, which is not only convenient for users, but also improves the management efficiency of the water supply department. At the same time, through the analysis of water use data, the water supply department can understand the user’s water use habits and rationally plan the allocation and supply of water resources
