An HID access control reader is necessary to have a reader card. Usually, this access control reader is installed close to an access area and is programmed when the card is near the reader.


How an HID Proximity (Prox) Card is Reading

Most HID card readers are durable and weatherized to withstand outdoor elements and usually support a wide range of different prox cards.

The proximity card or control cards are the option with a contact information stored.
The data are read and transmitted to an HID access control panel to secure the access.
A spiral antenna and a microchip with a specific number code inside the access control card or a keyfob determine the range of readers.
An HID card ise an a radio frecuence (RFID). The cards are delivered fully coded, and they are identifiable by antenna RFID by the receptors in the card. Which are read, when the information is coded, is exchanged with the reader, and then the data is authenticated.
The HID prox cards are the gold standard technology.

Elements of a Card Access System

Any HID card reader access system consists of four essential elements. Depending on the system’s size and purpose, there may be many additional types of devices; however, the four essential elements are:


Readers (sometimes equipped with keypads)

Access control panels (controllers)

A user interface or “Host” P


HID access control is one of the leading manufacturers of proximity cards. It is one of the standards of prox HID access control systems. They are simple to use and are compatible with all HID proximity cards readers. PVC HID cards are easy to print on and create designs. HID security cards are commonly using for access control in office buildings, campuses, schools, and universities.

Standard readers convert the binary data into a protocol for transmitting to the access control panel (the controller). Each reader can only talk to its corresponding card type due to the unique technologies used in each.

Some readers can also communicate with the controller by other means, such as RS232 or Clock & Data.

User Interface or Host PC

The user interface is used to manage the HID access control system on the day-to-day, including:

  • Adding or deleting cardholders
  • Managing access privileges
  • Creating and modifying schedules and lists
  • Configuring system hardware
  • Monitoring events in real-time
  • Generate reports

Sometimes, in some large or complex systems, the host can decide who access, except for most systems, to whom the controller makes the decision.

Upping Security with Mutual Authentication

The HID card reader has a complex systems to compare the security passwords on the reader. That process is called mutual authentication, ensuring the communication between the card and reader.

The password must match the card for the authentication process to be properly completed. The password is never to be repeated.


Innovative – Leverages standard communications technologies for a mobile solution that is interoperable with iOS® and Android™-based smartphones.

Convenient – Activate with a tap or “Twist and Go” gesture to open doors easily, merging security with convenience.

Dynamic – Increase operational efficiency by managing mobile access through a robust, streamlined portal.

HID Access Control Panels (Controllers)

The controller is unique which can process the card code. The software works in a process that decides if it allows or not access. According to some stages:  

  1. Data match with the controller. 
  2. The structure must comply with the parameters of the controller.
  3. The card number is within the assigned range.
  4. If matches with the installation code.
  5. If the card is valid at that moment. 

The controller’s functions are different, according to the brand. Some of them register a message for each result of denying access. Other brands have a general register, and others ignore the conflicting information.

To solve any performance problem is essential to understand the real capabilities and options from the controller.

User Interface or Host PC

That is used to manage the HID access control day-to-day, including: 

  1. Managing access privileges. 
  2. Create and modify lists and times. 
  3. Configure the hardware system. 
  4. You can add or delete the holder card.
  5.  Monitoring the system in real-time. 
  6.   Generate reports. 

Sometimes, in some large or complex systems. The host can decide who can access it. Therefore, in general, the decision is made by the controller.

HID Mobile Access

HID Mobile Access® opens doors in a whole new way. Our innovative, patented gesture technology twists the mobile device upon approaching a door or parking gate for seamless access.

HID has an excellent reputation due to its evolution in access control systems, including the HID access control mobile.
