Contactless RFID Card for Access Control

Whether you would like to improve your security system, or would like to create a new one or wish to expand the one you've got, contactless RFID cards will be the best options and acts an excellent choice for countless reasons. You can even make use of different types of access control ID card procedures, new systems and innovative technologies, there are countless advantages that you'll gain from using a contactless RFID card as different to other types of ID card technology.

Access control becomes safer with the use of contactless RFID card. It is easier, safer, and because the contactless RFID cards may use numerous other technologies, like holographic lamentation, microchips and serialized bar codes in its design. They are frequently created with exclusive numbers translated with 64-bit random keys and protected by distinct encryptions like DES. By using typical encryption practices and random, diverse keys to nourish the card reader, contactless RFID cards can offer higher measures of access controller and information, and a strictly reduced rate of fake and duplication.

Contactless RFID card also make access control calmer because of their ability to carry different types of IT application data. These cards have the skill to host IT applications such as digital signatures, secure network logon information, biometric data, encryption, and more. They are great alternative to old-style security measures, such as passwords. RFID card can transmit such important information as date of birth, name, health history, and even assurance information stored on a microprocessor that can be processed by an rfid stickers and fed into a computer. Breaks of security happen most of the time, especially information security.

These RFID cards that are contactless are also an exceptional remedy to these crimes, on condition that better access control for safety systems. In fact, they are being used ever more as the time is passing by in different sectors across the globe, especially in both the administration (government) and the IT industry.

People using the RFID card can control and select their own access keys. This is a big advantage because it provides to have control over their own information, and this can make them far safer. If they know that they are capable to outline and control their own access keys, it will make them more at ease in their grind, environment and impart more self-assurance in their company and its safekeeping system.

Three Commonly Applications of RFID Cards

Proximity cards are a type of RFID cards. They store information and use radio frequencies to interact with card readers. Card readers are devices that process data transmitted from proximity cards. According to what a reader has been programmed for, it can allow or deny access to a building and it can track books borrowed from library etc.

There are two kinds of RFID cards - passive and active. Passive cards operate on energy extracted from card readers. They have a small range; less than five centimetres. Active cards come equipped with a lithium-ion battery. They have a longer range - approximately 150 meters. A downside of active cards is that their battery runs out and renders them unusable after between five and seven years of use.

Here is a summary of the three commonly areas where RFID cards are used:

(a) Identification cards
Modern RFID powered identification (ID) cards look just like the cards of 10, 20 years ago. Superficial appearances are deceptive. The functioning of these cards bears little resemblance to the cards of a generation ago. These are more secure and capable. Students and members of the faculty can use them for access, purchases, payments, and several other tasks. So many colleges and universities use them as ID cards.

(b) Library loans
Libraries are showing an interest in RFID systems. Libraries desire to decrease costs by cutting down on their staff number and replacing them with a self-service system based on RFID cards. Researchers are looking into how much libraries can earn in savings. A few researchers claim proximity cards start to pay back between two and three years; while others maintain that libraries should not expect a return on their investments before six years.

(c) Logistics
Supply chain managers are increasingly using RFID tags to better track their products. The use of these cards permit them to learn about their products' location with an accuracy of few meters; and at very low investments.

Additional uses
RFID cards are being considered as an alternative payment method in transport. Their use in security systems has a long history and it is going to last for a long time.

Types of RFID Cards play a role in our life

There are a myriad of card types, but in the real world you are likely to come across the following ID cards:

Standard plastic card
Also known as: PVC card
Description: A simple plastic card, with no added features like magnetic stripes or chips.
Applications: ID only with no access control or payment.

Magnetic stripe card
Also known as: Mag stripe card, Hi-co card.
Description: A plastic card with a magnetic stripe on the back.
Applications: Magnetic stripe is used for access control or for payment.

Contact chip card
Also known as: Smart card, Chip card.
Description: A plastic card with a visible chip on the front of the card. Contact is required between the chip and the terminal for the chip to operate.
Applications: Chip is used for access control or for payment. Their speed and relative low cost has made them the choice for credit cards and ATM cards.

Contactless card
Also known as: Proximity card, Prox card.
Description: A plastic card with a chip embedded inside the card, which is attached to an antenna, so that the chip can operate by radio-frequency, meaning no physical contact is required. Most of these cards are known as proximity cards, as they only work at short range - between a few inches to a few feet.
Applications: Chip is used for access control or for payment. For access control, contactless cards are better than contact chip cards for outdoor or high-throughput uses like parking and turnstiles.
