• The standards from ISO/IEC and ECMA define the physical characteristics such as RF (Radio Frequency) modulation schemes, data transfer speed and frame formats. Along with these, NFC Forum has defined the data exchange format protocol called NFC Data Exchange Format (NDEF) which helps to store various data types like URLs.
• To perform NFC based communication, the setup needs a pair of two NFC devices such as an NFC Reader/Writer device and any NFC Tag or another NFC Reader/Writer in close proximity. An NFC Reader/Writer or NFC tag technology shall be integrated in hand-held devices, and nowadays many of the smart phones provide NFC support. NFC tags contain data with ...
• Passive P2P communication is used when the target counter part device does not have any capability to generate any field, such as tags which only has the memory. This feature is also being used as a way of power saving.
• It is also possible to consume minimal power and still act as a passive device without using the external RF field.
