HID proximity is a card having same size to that of credit card or driver’s license and is used to open a number of doors for the card holder. HID Prox actually nests embedded information used for the activation and opening of doors. However, this card cannot fully function itself, for it to fully access the area, combined system should be employed. The combined system can now operate paving way for specific area security.  Additionally, these cards contain additional items such as card readers, computer enhancing the functionality of this system and above all, the control panel which is only accessed by authorized person or the owner.

As fully working system, it plays the primary role of security officers by scrutinizing credentials and only allows people who are authorized to enter the building at a particular time. In HID Prox card is a binary code of only zeros and ones. The two digits are arranged in a unique sequence qualifying the HID proximity to be unique and special card.  The picking of code format is basically done by card reader which in turn transfers this code directly to control panel. In the control panel, analysis of the code is done and decides whether the cardholder is actually authorized to walk into this building.  Some cards lack extra code in this card whereas others possess additional codes for the card reader.

After the HID Pro card reader transfers the code directly to control panel, the controller begins to process this code. In the preliminary processing stage, the controller undertakes the analysis of data string length followed by code formatting. In the case where the code received complies with specifications put down for a particular door, it goes ahead to review both site code and facility code. For further code review, the HID Proximity site and facility code must match with specifications set by this system.

Next, after the received code has been found matching with the set criteria by particular controller system, card number is finally reviewed.  This card number might be authorized for only at a particular time of a certain day. The controller will finally analyze whether this card matches with authorization dates and time as specified.  If all specification matches, automatically the lock opens and finally the door opens. However, if when analyzing the card something was found not matching with system specifications, the door will never open.  Many HID Pro systems responds by giving a probable reason of not opening the door but some do not give any response. For those in this stressing situation, contact HID Proximity security maintainers to alter the information.  The alteration of this system is enhanced by a computer.

This software application applied through the specified computer allows authorized people update their card information, deactivation or enable the activation. It can additionally configure locking system and the door, enhancing accessibility of hardware and give reports about this system and its operation. HID Prox is important in that it work all the time and unauthorized cannot access the specified area. It enhances total security.

Learning basic information about HID Proximity will assist you understand HID proximity system. The knowledge gained on HID Proximity is crucial for those who plane to use the system.
