Proximity Cards and Proximity Card Readers5398241
Proximity cards are used extensively by companies that want to control the physical locations that their employees 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 close to the proximity reader to acquire access to the physical area.
The proximity card reader receives the information stored on the card, which is then transmitted to the computer network. It is the computer system that will determine if a person will be offered access to the restricted area, or whether or not access will be denied, depending on earlier configurations. Proximity cards are a form of smart cards that controls access.
These smart cards provide both physical access control, and logical access control. Proximity cards are used a fantastic deal in business, simply because they permit the employer to offer access to not just physical areas, but also pc networks, and other resources of the company. Areas of a pc network can be made accessible or blocked based on an employee's clearance. They can also be used for simpler tasks such as web authorization, encryption of email, and digital signatures, to name just a few.
Restricted locations may be off limits to the majority of workers, which can easily be implemented with proximity cards while at the same time supplying access to these that should have access. It could also be precisely the opposite.
Proximity readers are fairly easy to install, and they come with a extremely 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 require to come directly in contact with the reader. You can be as far as an inch away from the reader and it will still be able to read it. That's why they are used so frequently 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 provides a fantastic deal of convenience, particularly in door technology. These systems allow you to be even further away than one inch. It's like walking through an unlocked door, yet it's precisely the opposite - as safe as Fort Knox. A credit size card can be kept in an employee' short case, wallet, purse, or even a pocket and when the employee walks past the door it automatically unlocks.
Proximity cards are very versatile, however an additional purpose why they have been such a big hit in businesses. You can set up them almost anyplace. You can install them on doors to various buildings or locations of a building, computer systems, washrooms, lunch rooms, and the list goes on. There truly are couple of circumstances 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 don't generally pose a issue for the proximity readers, simply because they either have a battery back up system or sometimes they use rechargeable batteries. So you by no means have to be concerned that your system becomes vulnerable if the power goes out.
There are a number of different proximity card systems. In fact, you can even use your Bluetooth cell phone as a proximity card for laptops that are Linux based. Of course that's not how most business will use it, but it is just an additional instance of the versatility of these systems.
