Proximity Cards and Proximity Card Readers8241611
Proximity cards are used extensively by companies that want to control the physical areas that their workers are in a position to access. A proximity card is issued to each employee and proximity card readers are installed in suitable physical places. Each employee must then pass their proximity card close to the proximity reader to gain access to the physical region.
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 figure out if a individual will be given access to the restricted region, 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 offer both physical access control, and logical access control. Proximity cards are used a fantastic deal in business, because they permit the employer to offer access to not just physical locations, but also pc networks, and other resources of the company. Locations of a computer 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 email, and digital signatures, to name just a few.
Restricted areas might be off limits to the majority of employees, which can effortlessly be implemented with proximity cards whilst at the same time providing access to these that should have access. It could also be exactly the opposite.
Proximity readers are fairly easy to set up, 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 don't need 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 in a position to read it. That's 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 get in touch with with the reader's magnetic face.
Distance proximity technology provides a great deal of convenience, particularly in door technology. These systems allow you to be even additional away than one inch. It is like walking through an unlocked door, however it's exactly the opposite - as secure 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 previous the door it automatically unlocks.
Proximity cards are extremely versatile, however an additional purpose why they have been such a big hit in companies. You can install them almost anyplace. 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 few circumstances 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 do not usually pose a problem for the proximity readers, because they either have a battery back up system or occasionally 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 various 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 example of the versatility of these systems.
