Question

1. Radio Frequency Identification. What are advantages and disadvantages of RFID technology?
2. Why is information security often viewed as an inconvenience or roadblock? What, if anything, can be done to change this way of thinking?

Answer 1

Solution:

1) Advantages of RFID

-- It can collect information without the human intervention requirement. That Tthus is often cheaper than scanning bar codes, or performing other manual processes.

-- RFID gives location to the reader along with its ID

-- It permits the users to build a huge variety of applications that go well beyond data collection.

-- The technology is versatile in nature and thus smaller and larger RFID devices are available as per the requirement

-- RFID is highly accurate, thus indicating that the data stored in an inventory-management, warehouse-management or other system is accurate and can be relied upon.

-- Tags can be read only as well as read/write as in case of the barcodes

-- The tag and reader need not to be in LOS to make the system work

Disadvantages of RFID

-- Active RFID is expensive due to usage of batteries.

-- The devices of RFID need to be programmed which requires huge time

-- The external interference by electromagnetic can limit the remote reading of RFID

-- The range of by coverage RFID is limited which is about 3 meters

-- In RFID privacy is a concern with the usage of on products as it can be easily tapped or intercepted.

-- The RFID reader finds difficult to read the information when the tags are installed in liquid or metal products
-- The signal frequencies of RFID across the world are non standardized
