Explanation:

Near field communication, NFC, is a form of contactless communication based on electromagnetic radio fields between devices like smartphones or tablets. Contactless communication allows a user to wave the smartphone over a NFC compatible device to send information without needing to touch the devices. Near field communication can connect to devices at a maximum distance of about 4 centimeters. To protect sensitive information like credit cards NFC can use encryptions.
