How Near Field Communication Works ...
Bluetooth and Wi-Fi seem similar to near field communication on the surface. All three allow wireless communication and data exchange between digital devices like smartphones. Yet near field communication utilizes electromagnetic radio fields while technologies such as Bluetooth and Wi-Fi focus on radio transmissions instead.
Near field communication, or NFC for short, is an offshoot of radio-frequency identification (RFID) with the exception that NFC is designed for use by devices within close proximity to each other. Three forms of NFC technology exist: Type A, Type B, and FeliCa. All are similar...

What is NFC & how does it work? - Android Authority
Passive NFC devices include tags, and other small transmitters, that can send information to other NFC devices without the need for a power source of their own. However, they don't really process any information sent from other sources, and can't connect to other passive components.� These often take the form of interactive signs on walls or advertisements.
Active devices are able to both send...

What is NFC? A comprehensive NFC definition.
�What is NFC: definition?
NFC, or Near Field Communication, is a short range wireless RFID communication technology. It means that two devices equipped with NFC technology are able to communicate with each other and share information as soon as they are close to one another. There is no need to launch an application, bringing the devices near each other automatically triggers the defined action...

Near Field Communication (NFC) Technology, Vulnerabilities ...
The Near Field Communication (NFC) is a set of standards for mobile devices designed to establish radio communication with each other by being touched together or brought within a short distance. The NFC standard regulates a radio technology that allows two devices to communicate when they are in close proximity, usually no more than a few centimeters, allowing the secure exchange of...

Modified Miller, 100% ASK
Man, 10% ASK
NFC employs two different codings to transfer data. If an active device transfers data at 106 kbit/s, a modified Miller coding with 100% modulation is used. In all other cases Manchester coding is used with a modulation ratio of 10%.
NFC devices are full-duplex--they are able to receive and transmit data at the same time. Thus, they can check for potential...
