Proximity Cards and Proximity Card Readers736196
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 suitable physical locations. Every employee should then pass their proximity card near 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 computer system that will figure out if a person will be offered access to the restricted region, or whether or not access will be denied, depending on earlier configurations. Proximity cards are a type of smart cards that controls access.
These smart cards provide both physical access control, and logical access control. Proximity cards are used a great deal in business, simply because they permit the employer to offer access to not just physical areas, but also computer 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 e-mail, and digital signatures, to name just a few.
Restricted locations may be off limits to the majority of employees, which can easily 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 fairly simple to set up, 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 able 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 get in touch with with the reader's magnetic face.
Distance proximity technology provides 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 through an unlocked door, however it's precisely the opposite - as secure 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 companies. You can install them nearly anyplace. You can install them on doors to various buildings or areas of a building, computers, 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 generally pose a problem for the proximity readers, simply 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 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 primarily based. Of course that is not how most business will use it, but it is just another instance of the versatility of these systems.
