Can Hid Proximity Card Contribute To Security?

By:


The MIFARE

MIFARE is a smart card technology with 13.56 MHz memory card on which chip data can be encoded by appropriate device like a card printer. It has a short read-range and originally developed for handling public transportation payment transactions. This card was used for public transportation networks in Asia, Europe and the US. Later, this concept was applied to building access and so as an HID access card.

However, in December 2007, Henry Plotz, a German Researcher and Karsten Nohl demonstrated before the Chaos Computer Club, a club of computer hackers, during the 24th Chaos Communications Congress, how they were able to hack the MIFARE chip showing its security vulnerabilities. As of today, there is limited use of MIFARE as an HID access card.

The Wiegand

The Wiegand is the trade name of the technology after its inventor, John R. Wiegand, used in card readers and sensors embedded in cards for access control. It has three small wires embedded in the Wiegand card in which the credentials are encoded during the manufacture of the individual cards. The industry standard 26-bit format is used where more than 16 million cards can be issued with unique numbers

It uses an industry standard 26-bit format with the possibility of being able to issue a total of 16,711,425 ID cards with unique numbers. The fact that a Wiegand card requires contact with the reader, makes throughput very low compared to the hid proximity cards. This low throughput and the necessity of imbedding the credentials on the card during the manufacturing process are the two glaring disadvantages that limited its use as an HID access card.

The HID proximity cards

The most popular among the RFID cards used in access control is the hid proximity card. The acronym HID stands for Hughes Identification which was spun off from the time of Howard Hughes, owner of Hughes Aircraft Company. The card is about the size of a driver's license, ATM, or credit card, and contains a programmable RFID chip with 125 kHz or 13.26 MHz frequency. The 125 kHz card is more known as proximity cards while the 13.26 MHz card as the iClass cards.

The card contains embedded information consisting of two components: the facility code and the card number. With these pieces of information, it is possible to infer the unique identity of the user. Every card that is authorized for one particular facility will have the facility number. The second number is then given to the card holder. With these two numbers it is possible to determine who is authorized to be in which location.

The moment the card is read, this information is then transmitted to the system's control here the data is analyzed. If approved, the access is granted.

This makes the HID access card made of HID proximity card very convenient and safe.

Conclusion

In the absence of any adverse findings on this type of HID access card made from a hid proximity card, it can be considered as the best for use in your company's access control system.

About the Author:
An HID access card is very different in operational details in comparison to an hid proximity card. Ask your professional consultant on which is uniquely right for you.
