RFID: The Advantages and Disadvantages
You may have heard about RFID several times but don’t really understand it. RFID stands for radio frequency identification. It refers to a technology that includes the encoding of digital data in RFID tags or smart labels. The digital data can then be captured by means of radio waves.
How Does It Work?
There are three different parts of RFID: RFID tags (or so-called smart labels), RFID readers, and antennas. An RFID tag is composed of an integrated antenna and circuit. The antenna is used to transmit data to each reader. Many people refer to this antenna as an interrogator.
RFID technology has been widely adopted. There are various sectors that have used this technology over the years such as logistics, chemical industry, and construction. Today, more and more companies are planning for an RFID door lock system to secure their buildings. RFID is very useful for a business’s security because of its flexibility in different industries and applications. However, behind the various advantages, RFID also has several disadvantages. The following is an explanation of the advantages and disadvantages of using RFID technology.
- Convenient to use – RFID cards only have to be in close proximity to a reader to work. That’s why most smart locks are based on RFID technology because it allows for easy and fast door unlocking experience.
- Size – The size of a card with RFID technology is generally almost the same as an ordinary KTP or ATM card. Thus it is very easy to store in a wallet. Users can carry their RFID card with them all the time.
- Variation – RFID locks can come in a variety of different sizes, so they can be adapted to a wide variety of doors and designs.
- Can be used for multiple accesses – A RFID card can be configured so that it can open more than one entry point. Traditionally, you would need 5 keys to open 5 different doors. However with RFID cards, you only need one card programmed for 5 different entry points.
Besides Some Of The Advantages, Rfid Technology Also Has Disadvantages:
- Still hackable – Even though RFID cards are sophisticated, they can still be hacked by someone who is tech-savvy.
- Very dependent on power – RFID readers are usually very dependent on power supply, so if there is a power outage, the system will not function and the risk of burglary will increase drastically.
- Easy to lose – Since it is still a card, it can become misplaced or lost among other cards.
Given these advantages and disadvantages, make sure you properly evaluate if RFID technology is right for your organization even though many businesses currently use it.
