A contactless proximity card is a low-frequency radio transmitter which connects with a card reader through a code. This code must be up to date and valid for the holder to gain access. If all goes well, the reader will allow the holder to pass through quickly and efficiently.
HID proximity cards are also known as radio frequency identification cards. Radio frequency is used in a tonne of other products, and it is so well distributed to the point that this technology is actually pretty affordable! Due to its extensive use, the process has been refined so as an HID proximity card is as thin as a bank card. These cards are an advancement from swipe cards – more secure, just as compact and far more convenient!
An HID proximity card contains a chip that has been programmed with a unique code and a printed-circuit antenna. These cards don’t have batteries to charge themselves up, instead, the reader produces an electromagnetic field – known properly as the exciting field. This field creates enough energy for the card to spring to life and send its code. This code is specially encrypted to also communicate the owner’s name and any other additional information needed. This code is then decrypted by the reader, which will consequently allow access.
These cards are highly secure. This is because the card has to be close to the reader so as the power needed can be generated and the code can be sent. Such a short distance results in a nearly unbreachable signal, making it one of the safest options for access cards!
HID proximity cards are used for hotel room keys, access to the workplace, elevator use and for parking. They are favoured because they are more efficient than a swipe or scan system – making a company or building more functional and more organised. It is also very easy to alter the code that’s stored on these cards, meaning that access and identification information can be adjusted as needed. You can also see when a card has been used for attempted, and unsuccessful, entry. This is a great safety measure to put in place, as it can suggest when a card has fallen into the wrong hands. HID proximity cards can also be placed on hold or blocked when suspicious activity is going on.
HID proximity cards are read efficiently and securely. With so many benefits and precautions in place, there’s really no reason not to make your workplace more secure by investing in HID proximity cards!
