INTRODUCTION
Everyone usually dreams of technology getting unified and where certain aspects of our lives will be completely supported through a single technology. Consumer electronics as of today has become more fast, multifunctional and networked. Near Field Communication
(NFC) is ͚the͛ technology to make our lives easier.
NFC Exploited
What is NFC?
NFC is a short-range radio technology that operates on the 13.56 MHz frequency, with data transfers of up to 424 kilobits per second.
NFC is based on RFID and it allows connectivity to be achieved very easily over distances of a few centimeters.
NFC is not a proprietary technology NFC standards are defined by the NFC Forum, a global consortium of hardware, software/application, credit card companies, banking, network-providers.
First formed by NXP Semiconductors, Sony and Nokia.
How NFC works ?
Peer to peer mode

NDEF
(Data Exchange Format)
RF Layer ISO 18092 + ISO 14443

Communication Modes ͻ In reader/writer mode
(mandatory), the NFC device is capable of reading NFC Forummandated tag types, such as in the scenario of reading an NFC
Smart Poster tag.
NFC tags are passive devices that can be used to communicate with active
NFC devices (an active NFC reader/writer Communication Modes ͻ In Peer-to-Peer mode (mandatory), two NFC devices can exchange data. For example, you can share Bluetooth or Wi-Fi link set up parameters or you can exchange data such as virtual business cards or digital photos.
Peer-to-Peer mode is standardized on the
ISO/IEC 18092 standard.
