Proximity Cards and Proximity Card Readers4823687
Proximity cards are used extensively by companies that want to control the physical locations that their employees are in a position to access. A proximity card is issued to each employee and proximity card readers are installed in appropriate physical places. Every employee should then pass their proximity card close to 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 computer network. It is the pc system that will determine if a person will be offered access to the restricted region, or whether access will be denied, based on earlier configurations. Proximity cards are a form of smart cards that controls access.
These smart cards offer each physical access control, and logical access control. Proximity cards are used a great deal in business, because they permit the employer to offer access to not just physical areas, but also pc networks, and other resources of the company. Locations of a pc network can be made accessible or blocked depending on an employee's clearance. They can also be used for simpler tasks such as web authorization, encryption of e-mail, and digital signatures, to name just a few.
Restricted areas may be off limits to the majority of workers, which can effortlessly be implemented with proximity cards while at the exact same time supplying access to these that should have access. It could also be exactly the opposite.
Proximity readers are fairly easy to install, and they come with a very easy 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 nonetheless be in a position to read it. That is why they are used so often in parking garages. That said, 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 allow you to be even further away than one inch. It is like walking via an unlocked door, however it is 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 extremely versatile, yet an additional purpose why they have been such a big hit in companies. You can install them nearly anyplace. You can install them on doors to various 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 can't 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 usually pose a issue for the proximity readers, because they either have a battery back up system or occasionally they use rechargeable batteries. So you never have to worry that your system becomes vulnerable if the power goes out.
There are several 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's not how most business will use it, but it is just an additional instance of the versatility of these systems.
