Access Control System – Value of Proximity Cards

Identification cards come in various models. Some of them are simple plastic cards that give the image and name in accordance with the person. Others may be even more extreme, depending on needs and desires of the organization. The contactless card is a smart card. Smart cards have built-in chips that store important information on individual needs. Depending on the size and security services of the organization may need limited access to some staff and the team members.A proximity card, access to all offerings area deemed necessary.
Each card has a built-in authorization code for certain regions. If an employee or a member of the team approaches in the field of access they need to analyze their card. If your card can be programmed for access to the entry, if not denied. This is called "physical access control. Proximity cards can be used. It just means they give access to computer systems. It allows to control an organization where employees can access certain areas of the computer network.Implementing also the proximity to the access logical drive is not very difficult.

control access very easy to use. As the proximity reader explains, is designed for playing cards. Some like it so far and inches are often used in places such as car parks. thirds must come in direct contact with the tape drive. using technology intimacy at a distance of a long journey. are in our environment is a hi-tech gate technology that can read the card in credit card format with a wallet or purse, the worker out the door. Naturally is the input, if the card drawn maps denied.Proximity when their value will be refused for the business thanks to their versatility.

You can get almost anywhere in the drives that you want to install. There is also a backup system in case of power failure. The system crash if power is lost. There are a variety of contactless cards in many places, you can use or do not come into contact on a daily basis. In many federal government buildings, the FBI, NASA and 'municipalities to use for proximity systems in some form. universities, hospitals and schools to use to use these systems as HID proximity cards the most popular proximity cards well.

One II ISO, Door Access Control System, These cards have a 125 kHz technology . In addition, comply with standards of ISO,, Door Access Control System, come with a glossy surface, and may possess more than 137 billion cards codes.Proximity created opportunities for organizations, which, Door Access Control System, seemed impossible at times. techniques for contactless cards is constantly in motion to create. What is generally practiced today can be obsolete tomorrow. But now, proximity cards can really help organizations in monitoring.

Proximity Card Reader
It is quite easy to install as well as use proximity card reader, as it is a highly simple access control system. It is based on a very simple mechanism. It is encoded in such a manner that it reads and responds to the various electronic signals received from access cards. Do not make the mistake of taking proximity card to be almost the same as swipe card used at ATM card reader. Unlike ATM card, you don't need to bring your proximity card in direct contact with the reader. Even if you show the card from a distance of an inch or so, it will work. It is used a lot in parking garages. However, there are a few proximity card readers that require you to touch the card on the magnetic face of the card reader.
Proximity card readers are known for their versatility. You can install them anywhere on the computer, office table or entrance of the building. Most of the proximity card readers use rechargeable batteries, while others have a battery back up system. As in the case of most of the access control systems, you can customize proximity card readers to accommodate passwords and usernames.

How an HID Proximity Card Works?
A proximity card by HID is a card with embedded information inside. The information does not have the capability of accessing a secure area within itself, but the card is part of a system that allows Access Control.

The card is part of a complete system that comprises of the cards, a Card Reader, an access Control Panel and computer. The system functions as a security officer that guards a secure area and allows only authorized individuals to enter.

The card contains an embedded binary code that identifies the card holder by a specific sequence of number. The card is read by a card reader close to the access door. The reader transfers the information to the access control panel for deciphering.

When the controller receives the data that is transmitted by the card reader, the controller begins processing the information. The controller first reviews the length of the data string and also the format of the binary code. If the controller can identify these items, the next step is to review the facility code and the site code for a match. If these items match, then the actual card number is review for a database match. If the number is present and the card number is allowed to activate doors during the time frame, the controller sends authorization to the lock mechanisms to allow the door to open.

Some systems will provide a specific negative response to the cardholder whose card is rejected. Other systems do not provide any response at all.

The system hosts the controller has a software application available so that security personnel can update and authorize card holder information. The system also has a system that will allow the door access hardware to be configured. Reporting functions are also available through the system.

Uses of Proximity Cards
Proximity cards are basically access control smart cards that offer its users the dual advantage of logical access control as well as physical access control. These cards are of immense use to enterprises, as they provide accessibility to computers, networks and last but not least resources of the organization. Thus, proximity cards can enable you to gain access to restricted area and computer system. These proximity cards have largely reduced the overall security cost of organization. In addition to it, these prox cards can also be used for varied other purposes such as email encryption, web authorization, digital signatures and many more.

Proximity Card Holder
A large number of employees use proximity card holders for protecting their proximity cards. It is usually used by people who need extra care of their proximity card. New varieties of proximity card badge holders are coming up in the market varying in style, color and texture. Cost differs from one type to another. The more the money you invest in buying proximity card holder, the better quality you get. More often, proximity badge holders come in the size of credit card.

RFID Proximity Card
Proximity RFID ISO card covers the Low frequency 125KHz, and High frequency 13.56MHz technology, To achievecontactless transmission of data, electromagnetic waves transmit the data between the RFID chip and reading devices. Lots of companies use proximity card to control physical access. An employee holds their card within a few inches of the reader.
The RFID proximity cards are optional with finely laminated blank card, and pre-printed cards. the pre-printed RFID cards are done in factory with offset printing, and silk-screen printing.
