NFC and RFID Quiz

How many distinct modes of operation are there with NFC?

• Two

• Three

• Four

• Five

In Peer-to-peer mode, what do two NFC-enabled devices do?

• Transmit data one-way

• Function as a contactless card

• Exchange information with each other

• Read data from a passive device

When NFC devices are in Peer-to-peer mode, what happens to their states?

• Both devices remain active.

• Both devices remain passive.

• They switch between being active (sending data) and passive (receiving data).

• One device is always active, the other always passive.

What characterizes the Read/write mode of NFC?

• It allows two-way communication between devices.

• It is a one-way transmission of data.

• It is used for card emulation.

• Both devices are active.

In Read/write mode, what role does the passive device play?

• It sends advertising data.

• It links up with another device and reads data from it.

• It functions as a smart card.

• It initiates the connection.

An example of when Read/write mode might be used is:

• Sharing photos between smartphones.

• Entering a metro system.

• An active tag sending out advertising data.

• Making a contactless payment.

What is the function of an NFC device in Card emulation mode?

• To exchange information with other NFC devices.

• To transmit data one-way to a passive device.

• To function as a smart or contactless card.

• To read data from active tags.

Card emulation mode is often used as a way of entering which type of system?

• Private car parks

• Public transport systems

• Warehouses

• Toll roads

What is the typical range of NFC?

• Up to 50 cm

• Up to 5 cm

• Up to 5 meters

• Up to 420 kilobits per second

What is the maximum transmission rate of NFC?

• 50 kilobits per second

• 420 kilobits per second

• 5 megabits per second

• 420 megabits per second
