The world’s leading logistics software development-Jilian New Software has successfully used remote access control, attendance, personnel identification management systems, conference room meeting sign-in, and permission open control. 26 short-distance swipe card access control points, 4 RFID long-distance swipe cards automatically identify access control attendance points.

Points to pay attention to when attending remote access control:
Long-distance access control: It is required that the card reading distance should not be too far, the best distance is 1-2 meters away from the door, and a distance of 0.5 meters on the left and right sides (carrying cards can be arbitrarily placed in pockets or purses), people walking from a distance just walk Read the card at a position about 1-2 meters in front of the door, and when the door is unlocked, the person pushes the door in. It happens at the right time without staying in front of the door.If it is an automatic door, enter the door just when the door opens
Automatic recognition and automatic opening of doors when entering and exiting.And has the attendance function, multiple people enter and exit at the same time without missing the card
The realization of long-distance access control requires a long-distance card reader
The omnidirectional range of the card reading is stable and has a clear boundary (it cannot be a phased pulse signal, which can be read very far suddenly, causing the door to keep opening for no reason),
The card reading range is within 3 meters (the door cannot be opened when a person walks on the road outside or walks indoors);
The card is not affected by the human body and cannot be shielded by the human body (the card cannot be read when it is put in the underwear bag or bag, or the card of the person behind cannot be read when many people are crowded in and out);
The conversion of the card angle has little effect on the card reading distance, and there is no dead corner in the card reading (it can’t be read only when you come in directly facing the door, and you cannot read the card from the side and cannot open the door).
There is no metal rebound (the polarized rebound of the metal rod can not cause the card to be read even in the card reading area)
Long-distance time attendance: The long-distance card reader is required to have a stable omnidirectional range, with a clear boundary, no phased pulse signal, and the reading range within 3 meters; the card is not affected by the human body and cannot be shielded by the human body; multiple reading Strong output ability, can not miss the card reading when many people are crowded in and out; the influence of the card angle conversion of the card reading distance is small, and there is no dead angle in the card reading. The card can be hung up, can be placed in the bag, can be placed in the inner bag of the clothes, held in the hand, or placed in the back trouser pocket.
It is necessary to never miss a card or record. (60 people crowded in and out at the same time without any missing cards)
The reserved personnel tracking and positioning function can realize the correct judgment of personnel entering and exiting. People who do not carry the card are forbidden to pass. The alarm cooperates with the camera to capture and the security control. (Tracking and positioning personnel of entrance and exit control management)
What’s more important is that the equipment installation is buried in the dark, nothing can be seen from the outside, it does not affect the appearance, and does not damage the design of the original building.
At the same time, it can cooperate with vehicle entry and exit management, consumption management, meeting sign-in, etc. to meet the general needs of general enterprises for the entire system of a card swiping.
The damage problem of the power and frequency of the card reader itself:
Everyone knows that high frequency has a strong radiation hazard to the human body. Long-term working and living under high frequency radiation environment seriously affect human health. Therefore, general high-frequency and UHF card readers are mostly used for logistics, transportation, assets and other non-living bodies.
Relevant studies have shown that the pathogenic effect of electromagnetic waves increases with the increase of the magnetic field vibration frequency, and the frequency exceeds 100,000 Hz, which can pose a potential threat to the human body. Working and living in this environment for a long time, the interference of electromagnetic waves changes the original electric field of the molecules in human tissues, and damages the various biological molecules that make up brain cells to a certain extent. Too much harmful metabolites such as peroxides are produced, and even the DNA codes of brain cells are disordered, producing some non-physiological neurotransmitters. If the human body is exposed to a radiation dose exceeding the safety standard for a long time, human cells will be killed or killed in a large area. —-“Hazards and Protection of Electromagnetic Waves”
Therefore, some applications such as access control, time and attendance, etc., to identify people, need to use low-frequency and long-distance card readers. The low-frequency card reader has low power, low frequency and small coverage. It needs to pass FCC certification and does not cause harmful interference to the human body and other equipment. The low-frequency card is a passive working mode. The card will only work within the antenna sensing range. Active has been working.The working power of the card is small, a battery can be used for 5-7 years
Generally, the following methods can be used to test the long-distance card reader used in personnel identification:
1. Hold the card in the palm of your hand, hold the card with both hands, enter and exit the recognition area, hold the card in parallel, vertically, and diagonally to see if the card can be read by the card reader. (Test the shielding effect of the human body, and the directionality of the card)
2. Put the card in your back pocket, enter and exit the card reading area, and see if it can be read (test obstacles blocking effect) or if multiple people walk next to each other, the distance between the front and back is less than 10CM
3. Wait outside the recognition area to see if the card will be misread (after the high-frequency card reader reduces the reading distance, there will be intermittent pulse signals, which can read far away cards. Commonly seen in long distances) The barriers can be opened by parked vehicles. When people walk around the office, the far door will keep opening)
4. Stay in the card reading area of a card reader to see the output signal of the card reader (test the working ability of the card reader, will it produce cumbersome signals and wrong direction)
5. Find 50-60 people to carry the card in and out of the gate at the same time, and check the card status. If there is a missing card, it means that this long-distance card reader is not suitable for use at all. Both get off work and school are peak periods. If the card is missed, employees will not go to get off work normally and students will not get out of school and school normally, which will seriously affect the emotions of employees and students, and affect work and study.
