Wireless Device Security

A software company has deployed a wireless technology to monitor employees’ attendance by recording their entry and exit times. Each employee has an entry card with an embedded tag. Whenever an employee enters the office premises, they must swipe the card at the entrance. The wireless technology uses radio-frequency electromagnetic waves to transfer data for automatic identification and to track tags attached to objects.

Which of the following technologies has the software company deployed in this scenario?

  • A WiMAX
  • B RFID
  • C Bluetooth
  • D Wi-Fi
Explanation

Radio-Frequency Identification (RFID) uses radio-frequency electromagnetic fields to identify and track tagged items. An RFID-enabled entry card can be read at an entrance to record an employee’s arrival and departure times.
