Proximity Cards and Proximity Card Readers8893394
Proximity cards are used extensively by companies that want to control the physical locations that their workers are able to access. A proximity card is issued to each employee and proximity card readers are installed in appropriate physical places. Each employee must then pass their proximity card near the proximity reader to gain access to the physical area.
The proximity card reader receives the information stored on the card, which is then transmitted to the pc network. It is the pc system that will figure out if a person will be given access to the restricted region, or whether access will be denied, depending on earlier configurations. Proximity cards are a type of smart cards that controls access.
These smart cards provide each physical access control, and logical access control. Proximity cards are used a great deal in business, because they allow the employer to provide access to not just physical locations, but also pc networks, and other resources of the company. Locations of a pc network can be made accessible or blocked based on an employee's clearance. They can also be used for easier tasks such as web authorization, encryption of e-mail, and digital signatures, to name just a few.
Restricted locations might be off limits to the majority of workers, which can effortlessly be implemented with proximity cards whilst at the same time supplying access to those that should have access. It could also be exactly the opposite.
Proximity readers are relatively easy to set up, and they come with a very simple to use access control system. It is encoded in a way that it easily reads and responds to electronic signals that are sent by the card and received by the reader. Proximity cards do not need to come straight in contact with the reader. You can be as far as an inch away from the reader and it will still be in a position to read it. That's why they are used so often in parking garages. That stated, there are a handful of readers that require the proximity card to come in contact with the reader's magnetic face.
Distance proximity technology offers a fantastic deal of comfort, particularly in door technology. These systems permit you to be even further away than one inch. It is like walking via an unlocked door, however it's exactly the opposite - as safe as Fort Knox. A credit size card can be kept in an employee' brief case, wallet, purse, or even a pocket and when the employee walks past the door it automatically unlocks.
Proximity cards are extremely versatile, however another purpose why they have been such a big hit in companies. You can set up them nearly anywhere. You can set up them on doors to numerous buildings or locations of a building, computers, washrooms, lunch rooms, and the list goes on. There truly are couple of situations exactly where a proximity system cannot be used. The card readers read and respond to encoded electronic signals from the proximity (access) cards. And they will respond only to cards that are authorized.
Power outages do not usually pose a issue for the proximity readers, because they either have a battery back up system or sometimes they use rechargeable batteries. So you never have to be concerned that your system becomes vulnerable if the power goes out.
There are a number of different proximity card systems. In reality, you can even use your Bluetooth cell phone as a proximity card for laptops that are Linux based. Of course that is not how most business will use it, but it is just another example of the versatility of these systems.
