Can Hid Proximity Card Contribute To Security

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.

Types Of Materials Used For Manufacturing The Mannequins

The three main materials used to manufacture mannequins. They include fiberglass, polystyrene, and wood.

Wood is the oldest mannequin material. Some benefits of wood include sturdiness. Moreover, customization can be carried out on a small scale quicker than other materials. Wood can be designed with ball and socket and other joints that permit limitless articulation. Wood also can be painted lifelike, or used naturally in the abstract permitting a variety of different styles.

Of course there are negative aspects of wood mannequins. Inherently they are extremely heavy which causes challenges in handling and increases the cost of transportation. Moreover, wood inherently is more abstract and does not lend itself to representing the most lifelike perceptions of humans. Over time wood will crack and split and it is virtually impossible to disguise these natural imperfections.

Polystyrene mannequins have come onto market in the past 15 years for a variety of reasons. First, this type of plastic is virtually indestructible and has a longer lifetime. Moreover, polystyrene is lighter weight than other materials and presents a cheaper transportation cost to the consumer. Also, polystyrene can be injected with dyes and formed into a variety of aesthetically pleasing colors. Pleasing the buyer, polystyrene mannequins are often the cheapest cost mannequins to manufacture.

The flipside to polystyrene is the difficulty in achieving realism. It cannot be sprayed over with lifelike paint and thus the mannequin can only achieve abstract renditions. Moreover, the mold is extremely expensive to manufacture due to the precision required and the selection of styles and poses and restricted. Finally, the finish and look of polystyrene matches its price; it is a cheaper looking product.

Fiberglass mannequins have moved to the front as the preferred mannequin manufacturing material. The reasons are clear. Fiberglass achieves adequate sturdiness matched with weight. Assuming adequate care is taken in packaging and shipping, fiberglass mannequins will ship for a moderate price and last a long time. Fiberglass can be touched up with paint or painted over completely, should the consumer require a different look. Paints adhere well to fiberglass and artists can render the most lifelike renditions over a fiberglass surface. Fiberglass can be constructed with fabricated joints to permit some posing and articulation in the joints. As fiberglass mannequins are the most preferred construction material the price point, due to competition, is the lowest for these types of mannequins.

The downside to fiberglass is sturdiness. While dropping a body part a few inches will likely not cause extensive damage, knocking a rigid fiberglass mannequin onto the floor from a standing position will likely result in shattered pieces. Moreover, fiberglass tends to scratch easier than other materials and will have to be touched up more frequently. Fiberglass mannequin paint, when placed inside a non-UV protected retail window will fade when exposed to the sun quicker than other materials.

While there are three primary materials utilized in mannequin construction fiberglass has emerged as the preferred. Fiberglass’s price, sturdiness and realism are the most important factors driving consumer purchases of mannequins.

Hydro-Electrenergy

In my previous article I described how important the energy was to our preferred lifestyle. In this article I will lead you to delve down into the sources of energy. The energy that now becomes inseperable part of our lives and how we obtain it has been impacting our way of live. There are three major formations that we obtain energy: Natural gas, electricity and crude oil. Natural gas is a product of fossil deposits produced by nature which certainly takes a very long time. It is a type of carbon composition being trapped deeply underground. We use natural gas in limited ways comparing with electricity, infact all functions that are fueled by natural gas can be replaced by electricity. Electricity is widely used in our way of live. Anything we want to nourish our preferred lifestyle, electricity can make it all happen. Electricity is a man-made product that can be obtained by consuming the fossil deposits such as coal, shale, woods, crude oil. We burn these fossil deposits in order to generate energy in the form of electricity and deliver through the grid. That is how energy will be available wherever it is needed. Crude oil is another type of the fossil deposits. It is a carbon composition preserved underground in the form of liquid. It has to be refined so that the machinery can consume. We use crude oil for all types of machinery. It has become the important fuel for our transportation needs. Over a century ago we lived on the oil from whales as our energy. At some point of time we came to realize that if we kept killing them for oil. Sooner or later there would be no whales left for the new generations to come. At the mean time we discovered these fossil deposits to replace the oil from whales. They were plentiful and effective but wouldn’t it end up with the same problem? Eventually, there will be nothing left. We have plenty of these fossil deposits in some different forms at the present time, plentiful supply that we can use until some of us may feel not to worry about. But with increasing numbers of population due to:- -the multiplication of reproduction on every new generation. -the advanced technologies in medical science that help fighting against any influenza epidemic that frequently attacks and kills people in large numbers. -the new nutritional researches that make people live longer and healthier. -the great efforts to study on big accidents like aviation related accidents that kill people in large numbers all at once, in order to prevent them from happening again. -the great wars like WW I & II are less likely to break out any more. The new generations start to realize more value of being born as human being. They are prone to settle down calmly over the conflicts that could lead to wars. All these factors point to the only one thing which is more population as the time goes by and everyone of us needs energy to live on. It will be a huge mistake if we continue living on our lives not to prepare for this situation. The depletion of fossil deposits may not occur in our generation or a few generations ahead. But it certainly will occur because the rate of replenishment by nature of these resources can not catch up with the rate of our energy consumption. There are no arguments against this term. We are living on borrowed time and the clock is ticking. Eventually, we all will have to pay back and it will be painful and expensive. Not to mention about the inauspicious circumstances that are created day by day to augment the effect of global worming on our natural surroundings. It has been a very long time since humans learn how energy can enrich their lives and they have striven to obtain the energy from different sources. The sources have been changed from time to time to be benign for environment and more reliable. Despite all the efforts, we have gone on the wrong track time after time. We live on with no plans at all when it comes to energy. It’s time to make a change now folks, once and for all. Because a right choice is now at our disposal. Join me on this fight, it will be a fight to draw solid plans for our certain future and a clean planet to live. Finally, we can have solid plans for all. Go to http://hydro-electrenergy.com and participate in. Watch for my next article about free energy for eternity. I have a solid plan to reveal. We can eventually extricate ourselves completely from carbon footprint.
