Keyless Entry Card System for Commercial Business

Smart, keyless, contactless, RFID, key card, access card, entry card, FOB, swipe card - whatever you decide to call it - they all revert to the same branch of card functionality.

To keep things simple we'll stick to the term smart card. A smart card can be used in several ways, where many of us would have undoubtedly used a smart card at one point in time either as a form of bank card, personal identification or public transportation card.

The focus of this article will be on ‘access cards’, another form of smart cards.
 
An access card is a type of electronic access method that has become an increasingly common access solution in the commercial and industrial sectors due to its effective security solution and access efficiency in the work environment. Currently, there are two primary types of access smart cards being used: magnetic stripe cards and proximity cards.

Magnetics Swipe Card and Proxy Card, What’s the Difference?

‘Keyless Entry Swipe Cards’ 

  • Capable of storing data by modifying the magnetic material on the card stripe.
  • The magnetic stripe gives the name swipe card for this access system.
  • For access-based uses, these cards are highly desirable due to their ability to transfer tracking data and access control.
  • Ability to implement a cloud-based ID card system for easy access to tracking data.

Proximity Cards or Proxy Cards 

  • Unlike magnetic swipe-cards, proxy cards do not utilise tracking capabilities and cannot contain usable data, however, they do not require any form of swiping or contact with the card reader.
  • The contactless efficiency thus allows the user to scan from a slight distance or through an object such as a wallet or phone case.

How Do Access Cards Function?

Access cards utilise a method called RFID or Radio-Frequency Identification. 

  • RFIDs are small embedded chips within the access card, similar to a sim card within your mobile phone, while the ‘Readers’ are the devices that you scan your card on to gain access, also similar to an EFTPOS machine.
  • RFID technology allows the ‘access card’ to connect to the reader through the power of radio waves, a type of electromagnetic radiation. Radio waves are commonly used in TVs, cell phones, and radios. Radio wave energy can naturally occur from lightning or astronomical objects, while artificial radio waves, on the other hand, are produced by electrical generators, power lines, appliances, and radio transmitters.

Electric Spikes

Another part of the electric card-based access system is called an ‘Electric Spike’. An Electric Spike is a device that provides added security and convenience and fits on all common and new door structures.

The electric strike fits specifically around the door frame, allowing the door to be electrically opened without the hassle of the physical key systemised process.

Why are Smart Access Cards so Affordable?

Smart cards employ RFID chip-based technology, which means:

  1. The access cards only require a small amount of data to function, this means it can be used  as a form of ‘pointing’ system into the direction of a more complex functionality device, that being the access card reader; and
  2. Access cards use very little energy, which allows the cards to be powered by radio waves.

Both the low usage of data and energy enable the aforementioned access card systems to be extremely affordable and convenient for security and access functionalities.
