Proximity Cards and Proximity Card Readers612819
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 locations. Each employee should then pass their proximity card near 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 pc network. It is the pc system that will determine if a individual will be offered access to the restricted area, or whether or not access will be denied, based on earlier configurations. Proximity cards are a type 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, simply because they allow the employer to offer access to not just physical areas, but also computer networks, and other resources of the company. Areas 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 email, and digital signatures, to name just a couple of.
Restricted locations might 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 relatively 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 get in touch with 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 is 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 get in touch with with the reader's magnetic face.
Distance proximity technology provides a great 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, yet it's precisely the opposite - as safe 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 past the door it automatically unlocks.
Proximity cards are very versatile, yet an additional reason why they have been such a big hit in companies. You can install them almost anyplace. You can set up them on doors to various buildings or areas of a building, computers, washrooms, lunch rooms, and the list goes on. There really are few 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 generally pose a issue for the proximity readers, because they either have a battery back up system or sometimes they use rechargeable batteries. So you never have to worry that your system becomes vulnerable if the power goes out.
There are several 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 is not how most business will use it, but it is just another example of the versatility of these systems.
