Why Use Prox Card for Access Control

In modern society, security and management efficiency are key factors for business success. Large office buildings, high-tech data centers, and busy university campuses all need efficient and reliable access control systems. Imagine that on a busy morning, employees and students can quickly pass the door control and enter the place they need by simply swiping the card in their hand. The prox card can provide this convenient and secure access method.

What is prox card and how it works

Prox card is an application of radio frequency identification (RFID) technology, and its working method is based on contactless data transmission. It usually contains a small antenna and microchip for transmitting and storing data. When the card is close to the reader, the antenna inside will receive the radio frequency signal emitted by the reader and activate the microchip. The microchip then sends its stored unique identification code to the reader through the antenna, and the reader transmits this information to the access control system for verification. If the verification succeeds, the system allows access. It completes the whole process within a few milliseconds, so users hardly feel any delay.

In addition, because the reader does not need to physically contact the card for verification, this reduces the possibility of wear and damage, thereby increasing the card’s service life.

Why prox card is suitable for access control

The main reasons for using prox card for access control are as follows:

Efficient and convenient: The use greatly improves the efficiency of passage. Users only need to bring the card close to the card reader for verification, reducing the inconvenience and time delay caused by physical contact.

High security: Each prox card has a unique identification code that is extremely difficult to copy, making illegal copying and counterfeiting extremely difficult.

Flexible: It system can easily add or remove user permissions without replacing the entire system.

Durable and reliable: It adopts a contactless design, which reduces physical wear and tear, so the card is more durable.

Strong integration capability: You can easily integrate the prox card system with other security systems to form a comprehensive security management system.

Take the RFID Card ATMEL®ATA5577 as an example. It has an embedded ATMEL®ATA5577 RFID chip, which can complete verification as long as it is close to the door lock, and it is very convenient to manage. The strong PVC material makes it more durable.

FAQs about prox card

1. What is the difference between prox cardand traditional magnetic stripe card?

Prox cards use radio frequency identification technology to transmit data without physical contact, whereas traditional magnetic stripe cards require swiping to read data.

2. What should I do if my prox cardis lost?

If you lose your prox card, notify the system administrator immediately.

3. Can the prox cardsystem record access history?

Yes, it can record the time and location of each card use.
