Wireless Device Security

Rickson, a security professional at an organization, was instructed to set up short-range communication between devices within a 10 cm range. For this purpose, he used a mobile connection method that uses electromagnetic induction to enable device-to-device communication. The mobile connection method chosen by Rickson can also read RFID tags and establish Bluetooth connections with nearby devices to exchange information such as images and contact lists.

Which of the following mobile connection methods did Rickson use in the above scenario?

  • A NFC
  • B Satcom
  • C Cellular communication
  • D ANT
Explanation

Near Field Communication (NFC) is an ultra-short-range, contactless technology that uses an electromagnetic field for communication. NFC devices can operate in reader/writer mode to read tags, and NFC tag data can contain Bluetooth pairing information that initiates pairing with a Bluetooth device. The NFC Forum also specifies connection handover for establishing a connection through another wireless technology, such as Bluetooth, when a longer-range or higher-throughput transfer is needed.
