RFID access control technology is a wireless RFID-based authentication system that uses RF signals to realize access control and identity authentication. It is based on RFID technology and integrates RF readers, RF read-writers and RF tags (also known as RFID cards or labels) in the access control equipment. The working principle of RFID access control system is described below.
1.RIFD card or RFID tag recognition: the user carries a card or tag containing an RFID chip near the access control reader. The reader communicates with the card or tag through radio frequency signals to read its stored information.
2. Information Verification: The access control system will read the information and pre-stored in the database of the authority to verify the comparison. This step usually involves the confirmation of the user's identity, as well as determining whether the user has access to the area of the authority.
3. Implementation of the open door operation: If the verification passes, the access control system will send commands to the door lock, the implementation of the open door operation. This process can be a mechanical lock unlocking, can also be the automatic opening of the electronic door.
4. Record and Feedback: After completing the door-opening operation, the access control system will record the user's entry and exit records and feedback relevant information to the management personnel. This information helps subsequent data analysis and security management.
How Long Is the Validity Period of an RFID Access Card?
The answer to the question of whether access cards need to consider the expiration date is that there is no expiration date.
What you need to know is the service life of the access card, there are physical wear and tear, magnetic stripe breakage, chip damage and other problems in the process of use, which may affect the normal use and security of the access card.
Introduction: RFID access control system compared to ordinary access control system in the identification method and speed, security and reliability, data management and analysis, as well as the degree of intelligence and so on have significant advantages. The following are the specific differences:
| VS | RFID Access Control System. | Traditional Access Control System. |
| Working Principle | Automatically identifies targets and reads relevant data using radio waves. | Identification is usually carried out by card swiping or password entry. |
| Recognition speed | RFID tags can be quickly authenticated by approaching the reader for contactless and efficient access. | Passage efficiency is reduced by using swipe card or password input for identification. |
| Security | Adopt digital identity credentials, with higher security. | There is a certain degree of security. |
| Reliability | Stable identification of multiple tags in and out of the direction of detection of unauthorized tags away from the area, automatically triggering sound and light alarms. | There is a risk of being copied, imitated, etc. |
| Data Management | Detailed data such as time, location, cardholder information, etc. can be recorded for each card swipe. | Only basic access information can be recorded, such as the time of card swiping and the person who swiped the card. |
| Data Analysis | Can be queried and analyzed through the background management software. | Cannot analyze the access data in depth. |
| Intelligence | Can link security, fire and other intelligent equipment, integrated to achieve intelligent security management. | Can only realize the basic access management function. |
Yes.
However, certain conditions must be met. On one hand, the smartphone must support NFC (Near Field Communication) functionality. NFC is a short-range, high-frequency wireless communication technology that allows for contactless, point-to-point data transmission between electronic devices. This functionality makes it possible for smartphones to simulate RFID access cards.
On the other hand, the smartphone must have the appropriate access card simulation software installed, and this software must be supported by the access control system. This means not all access control systems are compatible with the NFC functionality of smartphones. In practice, we also need to consider factors such as the security, stability, and legality of using smartphones to simulate access cards.
To some extent, even though smartphones can simulate RFID access cards, we need to treat this function with caution. On one hand, smartphones are essential tools in our daily lives, and their security is critical. If a smartphone is lost or stolen, the information from the access card may be leaked, posing a security risk. On the other hand, from a management perspective, if all employees use smartphones for access control, it could introduce challenges in managing and maintaining the access control system.
In conclusion, RFID access cards can indeed be used via smartphones, but this requires smartphones to have NFC functionality and for the installed access card simulation software to be supported by the access control system. At the same time, in practical applications, we need to comprehensively consider factors such as security and management. Therefore, when promoting the use of smartphones for access control, it is necessary to weigh the pros and cons to ensure that the convenience provided does not introduce unnecessary risks and challenges to our work and daily lives.
Yes, you can.
The recognition range of an RFID access card can be expanded through the following methods:
Using high-power RFID readers: Selecting RFID readers with higher transmission power can increase the recognition distance. Generally, the greater the reader's transmission power, the longer the recognition range.
Adopting active tags: Active tags are equipped with batteries and can actively transmit signals. Compared to passive tags, active tags have a significantly longer recognition range, typically reaching over 30 meters.
Optimizing antenna design: By optimizing the design and parameters of the antenna, the gain and directionality of the RFID system can be improved, thereby expanding the recognition range. For example, using directional antennas can concentrate signal energy and enhance long-range recognition capability.
Using higher frequency RFID technology: Ultra-high frequency (UHF) RFID technology, which operates in the 860 MHz to 960 MHz range, offers higher data transmission rates and longer recognition distances, making it suitable for scenarios requiring extended recognition ranges.
