Which of the following is a wireless communication that requires devices to be within 6in of each other to transfer information?

Bluetooth
Wi-Fi
NFC
4G

The correct answer is: NFC

NFC (near field communication) is a wireless communication technology that is used for short-range communication between devices, typically within 6 inches from each other. It is commonly used for contactless payments and data transfer. Bluetooth, Wi-Fi, and 4G are all wireless communication technologies, but they do not require devices to be within 6 inches of each other for information transfer. Bluetooth has a range of 10 meters, Wi-Fi can have a range of up to several hundred feet, and 4G typically covers several miles. Therefore, they are not the correct answers for the question.
