Certified Incident Handler (ECIH) — Question 23

A software company has implemented a wireless technology to track the employees' attendance by recording their in and out timings. Each employee in the company will have an entry card that is embedded with a tag. Whenever an employee enters the office premises, he/she is required to swipe the card at the entrance. The wireless technology uses radio-frequency electromagnetic waves to transfer data for automatic identification and for tracking tags attached to objects.
Which of the following technologies has the software company implemented in the above scenario?

Answer options

Correct answer: B

Explanation

The correct answer is B, RFID, as it specifically uses radio-frequency electromagnetic waves for automatic identification and tracking of tagged items. WiMAX is a long-range wireless technology, Bluetooth is designed for short-range communication, and Wi-Fi is primarily used for high-speed internet access rather than tracking attendance.
