Proximity Cards and Proximity Card Readers109875
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 near the proximity reader to acquire access to the physical region.
The proximity card reader receives the information stored on the card, which is then transmitted to the pc network. It is the computer system that will figure out if a individual will be given access to the restricted region, or whether 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, because they allow the employer to offer access to not just physical locations, but also computer networks, and other resources of the company. Locations of a computer 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 e-mail, and digital signatures, to name just a couple of.
Restricted locations may be off limits to the majority of employees, which can easily be implemented with proximity cards whilst at the exact same time providing 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 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 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 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 offers a great deal of comfort, particularly in door technology. These systems permit you to be even further away than one inch. It's like walking through an unlocked door, however it's exactly 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 nearly anyplace. You can set up them on doors to numerous buildings or locations of a building, computer systems, washrooms, lunch rooms, and the list goes on. There really are couple of circumstances 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 do not 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 be concerned that your system becomes vulnerable if the power goes out.
There are a number of various proximity card systems. In fact, you can even use your Bluetooth cell phone as a proximity card for laptops that are Linux primarily 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.
