What are the different types of key card systems?

Metal keys with jagged series of teeth are becoming increasingly rare, as technology improves. In places as diverse as hotels and office buildings, people use key cards instead of traditional key card keys. There are four types of key card systems: HOLCARDS, barcode cards, magnetic strip key cards and RFID cards). Each type offers easy use, some of which provide greater security than others.

Key card systems work on the relationship between plastic and electronic access control lock. Each card is programmed to respond to a specific key card reader, lock or lock set. The individual key card is programmed by a computer with a unique electronic signature. If stolen, magnetic band cards and RFID cards may have signatures changes and add security protection from theft.

Holecards are the oldest type of key card systems. In 1975, the inventor of Tor Sornes invented a system that would strikeIl series 32 holes for plastic card. The card would match the lock and open the door when it was inserted into the slot in the door. As the technology increased, this key card safety system has fallen out of kindness due to its coding limits, work associated with production and its fragility.

barcode cards were further innovations in key card technology. In this type of key card system, an individual barcode is created that corresponds to a specific lock and is printed on the card. The code is just like a barcode found on many products sold in stores. When the barcode is held under the electronic scanner, it unlocks the corresponding door. This type of key card has lost popularity when magnetic strips have become easier to access, as barcodes could be created and the electronic reader easily deceived.

Magnetic strip key cards are widely used in the hotel's diarrheaMysl and in security at the workplace. This card looks like a credit card with a thin metal strip on the back. This card ran them through the scanner as a credit card and opens the corresponding door for an electronic signature on the card. This type of card is much more difficult to create than girls and barcodes, which provides an added layer of security.

Systems key card RFID is a newer form of technology than girls, barcode cards or magnetic band cards. The RFID cards have a radio sensor chip inside the card. When the door is unlocked close to the corresponding programmed reader. The technology used by this type of card includes microchips and radio technology, so it is considered the most difficult and provides the highest level of security.
