Chapter 2.2.2 RFID Technology

What does RFID stand for?

• Radio Frequency Identification

• Radio Frequency Integration

• Radial Frequency Identification

• Radio Frequency Interface

What is the basic function of an RFID reader?

• To write data to RFID tags.

• To transmit data to RFID tags.

• The basic function of an RFID reader is to read data from RFID tags.

• To power RFID tags remotely.

Name one common application of RFID technology.

• Inventory tracking in retail

• Personal identification in security systems

• Data storage in cloud computing

• Payment processing in banking

How does RFID help in inventory management?

• RFID increases manual counting efforts.

• RFID eliminates the need for any inventory checks.

• RFID improves inventory management by enabling real-time tracking, reducing errors, and enhancing stock visibility.

• RFID only tracks items after they are sold.

What is one advantage of using RFID over barcodes?

• RFID can read multiple tags at once.

• RFID is more expensive to implement than barcodes.

• Barcodes can store more data than RFID.

• RFID requires line of sight to read tags.

What is a disadvantage of RFID technology?

• Incompatibility with existing systems

• Vulnerability to security breaches

• Limited range of communication

• High cost of implementation

How does an RFID tag communicate with a reader?

• An RFID tag sends data using sound waves.

• An RFID tag requires a physical connection to the reader.

• An RFID tag communicates with a reader by transmitting data via radio waves after being activated by the reader's signal.

• An RFID tag communicates through infrared signals.

What are passive RFID tags?

• Active RFID tags that have their own power source.

• RFID tags that require a battery to function.

• RFID tags that can only be read at short distances.

• Passive RFID tags are RFID devices that do not have their own power source and rely on an external reader for operation.

What are active RFID tags?

• RFID tags that only work within a few inches of a reader.

• Passive RFID tags that rely on external power sources to transmit signals.

• Tags that do not require any power source and are completely inactive.

• Active RFID tags are battery-powered devices that transmit signals autonomously, allowing for longer range and enhanced functionality.

In which industry is RFID commonly used for tracking animals?

• Agriculture

• Retail

• Healthcare

• Manufacturing
