Proximity Cards and Proximity Card Readers3975161
Proximity cards are used extensively by companies that want to control the physical areas that their employees are in a position to access. A proximity card is issued to every employee and proximity card readers are installed in suitable physical locations. Each 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 determine if a individual will be offered access to the restricted area, or whether access will be denied, based on earlier configurations. Proximity cards are a type of smart cards that controls access.

It is encoded in a way that it effortlessly 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 stated, there are a handful of readers that need the proximity card to come in get in touch with with the reader's magnetic face.

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 another reason why they have been such a big hit in companies. You can set up them almost anywhere. You can install them on doors to various buildings or areas of a building, computers, washrooms, lunch rooms, and the list goes on.
