In today’s era of rapid technological development, smart identification technology has penetrated all aspects of our lives, from clocking in at work to community access control, and various smart cards are emerging in an endless stream. Today, we are going to take a closer look at a unique product in the field of smart identification – the RW1990 Ibutton Card.
It is like a small smart key, seemingly ordinary, but contains great energy. Maybe you don’t pay special attention to it in your daily life, but it plays a key role in many access control systems, attendance management, and various scenarios that require identity recognition. So what kind of unique structure and magical functions does it have? Next, let us unveil its mysterious veil together.
Appearance and Sturdy Material of RW1990 Ibutton Card
When you see the RW1990 Ibutton Card for the first time, you will be attracted by its small, exquisite, and unique appearance. It is button-shaped as a whole, with a diameter of about 16mm and a thickness of usually 3-6mm. This size is very light in your hand and easy to carry.
Its shell is made of stainless steel, which is a very particular material. Stainless steel has excellent corrosion resistance and can effectively resist the erosion of water vapor and chemicals in the air. Even if it is exposed to harsh environments for a long time, there is no need to worry about rusting or corroding. Just like in some humid factory environments or the high-salt air environment at the seaside, ordinary cards may soon be damaged due to moisture and corrosion and cannot be used normally, but the RW1990 Ibutton Card can still maintain good performance and work stably with its stainless steel shell.
In addition to corrosion resistance, stainless steel also gives it the characteristics of durability. You can imagine that our access cards and attendance cards may be squeezed and collide accidentally. If the material is not strong enough, it will be easily damaged. But the RW1990 Ibutton Card is like a “little tough guy” that can withstand a certain degree of external force impact. Even if you accidentally drop it on the ground or even accidentally step on it, it is not easy to break or deform, which greatly extends its service life.
In addition, the stainless steel material also brings it excellent waterproof and dustproof performance. In terms of waterproofing, it can meet certain waterproofing standards. Even if it is accidentally wetted by water or soaked in water for a short time, the internal chips and circuits will not be affected and can still work normally. This means that on rainy days, you don’t have to worry about it being ineffective because of being wetted by rain when you take it out. In terms of dustproofing, it can effectively prevent foreign objects such as dust and particles from entering the interior, avoid the normal operation of the chip affected by dust accumulation, and ensure its reliability in various complex environments.
The Working Principle of RW1990 Ibutton Card
The reason why the RW1990 Ibutton Card can achieve such an accurate and efficient identity recognition function is that the working principle behind it is exquisite. It uses a unique single-bus transmission protocol, which is like an information highway. Although it has only one “lane”, it can efficiently complete data transmission and interaction.
In the single bus transmission protocol, the most amazing thing is that it can realize the dual functions of power supply and data transmission at the same time through only one data line. This is like a wire that can power electrical appliances and transmit various control signals at the same time. Isn’t it incredible? Specifically, when this data line is in an idle state, it is kept at a high level through an external pull-up resistor. When there is a need for data transmission, the host (such as the card reader in the access control system) and the slave (i.e., the RW1990 Ibutton Card) will send and receive data through a specific timing logic.
During the connection establishment phase, the host will first send a reset pulse, which is like a “knock signal”. It will pull the data line down for 480-960 microseconds and then release the bus. At this time, the bus level will jump from a low level to a high level due to the pull-up resistor, generating a rising edge. After detecting this rising edge, the RW1990 Ibutton Card will pull down the bus for 60-240 microseconds after a delay of 15-60 microseconds to generate a response pulse. When the host receives this response pulse, it indicates that the connection with the RW1990 Ibutton Card is successfully established and subsequent data transmission can be carried out.
During the data transmission process, the data is transmitted bit by bit on the data line in binary form. Whether the host sends instructions to the RW1990 Ibutton Card or the RW1990 Ibutton Card returns identification information and other data to the host, strict timing requirements are followed. For example, if the host wants to send a “0”, it will pull the data line low and keep it for at least 60 microseconds; if it wants to send a “1”, it will first pull the data line low, then release the bus within 15 microseconds, and let the pull-up resistor pull it high. Similarly, when reading data, the host first sends a read request, pulls the bus low for at least 1 microsecond and then releases it, and then reads the data status on the bus within 15 microseconds to obtain the data from the RW1990 Ibutton Card. Through such a rigorous and orderly working method, the RW1990 Ibutton Card can communicate with various host devices stably and reliably, and realize efficient identification and data interaction functions.
Powerful functions at a glance
The RW1990 Ibutton Card is very powerful and plays a key role in many scenarios, bringing convenience and security to our lives and work.
In terms of access control systems, it is a solid line of defense. When you carry the RW1990 Ibutton Card close to the access control card reader, the card reader will quickly read the identity information on the card. By comparing it with the authorization data pre-stored in the system, the card reader can determine the legitimacy of the card in a very short time. If the information matches, the access control system will immediately issue a command to drive the door lock to open, allowing you to pass smoothly. This process is not only efficient and fast but also extremely safe. Because each RW1990 Ibutton Card has a globally unique ID code, just like everyone’s ID number is unique and almost impossible to copy or forge. This effectively prevents illegal persons from entering restricted areas by forging access control cards, ensuring the safety of people and property in the venue. For example, in some high-end office buildings, scientific research institutions, and important government departments, the access control system uses the RW1990 Ibutton Card, and only authorized personnel can enter, ensuring the security and confidentiality of these places.
In the patrol system, the RW1990 Ibutton Card also plays an important role. It is a powerful “little helper” for security guards, property inspectors, and other positions that require regular patrols. Patrol points will be installed at various key locations on the patrol route. When patrolling, the patrol personnel only need to bring the RW1990 Ibutton Card close to the card reader at the patrol point, and the card reader will read the card information and record the time when the patrol personnel arrive at the patrol point. After completing the entire patrol task, the manager can upload the data in the patrol personnel’s handheld device to the computer for analysis through special software. Through these data, the manager can clearly understand the patrol personnel’s patrol trajectory, whether they arrive at each patrol point on time, and whether there are any missed patrols. This not only helps to improve the efficiency and quality of patrol work but also provides a strong basis for tracing possible security incidents in the future. For example, in some large residential areas, factory parks, and other places, by using the RW1990 Ibutton Card for patrol management, safety hazards can be discovered in time to ensure safety and stability in the area.
In the field of electronic door locks, the RW1990 Ibutton Card makes our lives more convenient and intelligent. Take the hotel’s electronic door lock as an example. When the guest checks in, the hotel staff will write the guest’s relevant information into the RW1990 Ibutton Card and give it to the guest as the “key” of the room. After the guest arrives at the room, just put the card close to the sensing area of the electronic door lock, and the door lock will recognize the card information and unlock it automatically. This method is more convenient and faster than traditional mechanical keys, and it also avoids the trouble of guests losing their keys. In addition, the electronic door lock system can also record the time of each unlocking, the card information used, etc., which is convenient for hotel managers to manage and query. If the guest checks out early or the card is lost, the hotel staff can cancel or reauthorize the card in the system in time to ensure the safety of the room. In addition, in some application scenarios such as smart apartments and home electronic door locks, the RW1990 Ibutton Card also performs well, providing users with a safer and more convenient life experience.
What are the advantages compared to similar products?
In the market of smart identification cards, competition is extremely fierce, and various products emerge in an endless stream. However, the RW1990 Ibutton Card stands out from many similar products with its unique advantages and has become the first choice of many users.
First of all, from the perspective of storage capacity, many similar products often have certain limitations in storage capacity, which makes it difficult to meet the growing demand for data storage. However, the RW1990 Ibutton Card has an outstanding performance, and it usually has a storage capacity of 8K. This capacity may not seem large, but it is more than enough for storing key data such as identity information and patrol records. Moreover, compared with some similar cards with smaller capacities, it can store more user information and usage records, providing richer data support for subsequent data analysis and management. For example, in the access control and attendance management system of large enterprises, it is necessary to record a lot of information such as the employee’s name, work number, department, attendance time, etc. The large-capacity storage of RW1990 Ibutton Card can easily cope with it, ensuring that all data can be saved completely and accurately.
In terms of reading and writing speed, the RW1990 Ibutton Card also performs well. The advanced technology it adopts enables it to reach a higher level of speed when reading and writing data. Under normal circumstances, its reading and writing time can be controlled at around 102 milliseconds. This speed advantage is particularly obvious in practical applications. When you pass through the access control quickly, you don’t need to wait for a long time. The card reader can quickly read the card information and open the door quickly, greatly improving the passage efficiency. In contrast, some similar products may have slow reading and writing speeds due to technical limitations, which can easily cause congestion at the access control and affect the normal work and life order. For example, during rush hour, if the office building’s access control system uses slow-reading and writing cards, employees will have to wait in line for too long, but the RW1990 Ibutton Card can effectively avoid this situation.
Security is undoubtedly one of the most important considerations for smart identification cards, and the RW1990 Ibutton Card is a leader in this regard. Each card has a unique 64-bit ID code in the world, which is like its “ID card”, unique and cannot be easily copied or tampered with. In addition, the single-bus transmission protocol it uses has a complete verification and error correction mechanism during data transmission, which can ensure the accuracy and integrity of the data and effectively prevent the data from being stolen or tampered with during transmission. In addition, its stainless steel shell is not only sturdy and durable but also can play an electromagnetic shielding role to a certain extent, further enhancing the security of the card. In comparison, some similar products may have security risks such as easy cracking of ID codes and insufficient data transmission encryption, which can easily bring security risks to users. For example, in some places with extremely high-security requirements such as financial institutions and military bases, if smart identification cards with poor security are used, it may lead to serious consequences such as information leakage and security accidents. The RW1990 Ibutton Card provides reliable protection for these places with its excellent security.
Practical Application of RW1990 Ibutton Card

In the corporate office environment, the RW1990 Ibutton Card also plays an important role. A large Internet company has adopted an access control and attendance management system based on the RW1990 Ibutton Card. When company employees go to work every day, they only need to bring the card close to the access control reader, and the system can quickly identify the employee’s identity, complete the attendance record, and open the access control. For some departments with a higher confidentiality level, only RW1990 Ibutton Cards with specific permissions can enter, which effectively guarantees the security of the company’s core technology and confidential information. In addition, the company also uses the card for conference room reservations and management. After booking a conference room, employees can use the card to unlock the door of the conference room, and automatically record the usage time and other information after the meeting, which facilitates the reasonable allocation and management of conference room resources and improves the office efficiency of the company.
In the field of public facilities, the RW1990 Ibutton Card also has excellent applications. For example, some cities have introduced this card in the public bicycle rental system. Citizens only need to write their personal information into the RW1990 Ibutton Card when applying for a rental card. When renting a bicycle, they can place the card close to the card reader of the rental device, and the device can identify the user and complete the rental procedures. When returning the bicycle, the card is also used for operation, and the system will automatically record the usage time and settle the fees. This method simplifies the process of public bicycle rental, improves service efficiency, and also facilitates citizens’ travel. Moreover, due to the uniqueness and security of the card, it effectively prevents the occurrence of fraudulent use and theft and guarantees the reasonable use of public resources and the interests of the operator.
Usage Guide and Precautions
Using the RW1990 Ibutton Card is not complicated, and you can get started in a few simple steps. Before use, first make sure that the relevant card reader equipment has been correctly installed and debugged, such as access control card readers, patrol point card readers, etc. Taking the access control system as an example, when you first get the RW1990 Ibutton Card, you need to bind it to the access control system. Generally speaking, the administrator will enter the card’s ID information into the system through special management software and assign corresponding permissions to it, such as which areas are allowed to enter and during what periods.
In daily use, when you need to pass through the access control, just bring the RW1990 Ibutton Card close to the sensing area of the access control card reader, and the distance is generally kept at about 5-10 cm. At this time, the card reader will automatically read the information on the card and compare it with the authorization data in the system. If the information matches, the access control system will emit a “beep” prompt sound, and the door lock will be opened, and you can pass smoothly. In the patrol scene, after arriving at the patrol point, the patrol personnel will also bring the card close to the card reader at the patrol point to complete the card punching operation and record the patrol time and information.
However, there are also some things to pay attention to during use. First of all, avoid strong impact and squeezing of the card. Although its stainless steel shell is relatively strong, excessive external force impact may still cause damage to the internal chip or circuit. For example, do not throw the card on the ground at will, or put it together with other sharp and hard objects to avoid scratching or damaging the card. Secondly, pay attention to waterproofing. Although it has certain waterproof properties, it cannot be soaked in water for a long time. If the card is accidentally wetted by water, it should be wiped dry with a dry cloth immediately to ensure that the surface is dry before use. In addition, when storing and using the card, keep it away from strong magnetic field environments, such as microwave ovens, induction cookers, large motors, and other equipment. Because strong magnetic fields may interfere with the data in the card, resulting in information loss or reading errors. Finally, it is also necessary to check the use of the card regularly. For example, in the access control system, if it is found that the card suddenly cannot be used normally, contact the administrator in time to check whether it is a card problem or a system failure, to solve it in time and ensure normal passage and management order.
