NFC technology, (Near Field Communication), is becoming one of the leading ways for communication to take place between mobile devices, objects and machines in the transmission or authentication of information.
NFC is a "contactless" interaction, allowing smart phones and other devices to communicate with each other via NFC chips applied to objects.
This efficient and easy method of communication allows the user to perform such contactless interactions as moving a smartphone in linear fashion across items in a store to read them, passing near a piece at a local museum to get more information, or interacting with a friends mobile device in order to share information or games. Near field technology allows you to pay, play, learn and authenticate with ease.
Areas of NFC application:
NFC operates in the radio frequency spectrum 13.56 MHz, but less than 15 mA power to communicate data over distances of less than 20 cm.
NFC tags typically store between 96 and 512 bytes of data and transfer data using a speed of 106Kb / s, 212KB / s, 424kb / s, or 848KB / s - enough to move small packets of information almost instantly .
The NFC interfaces are defined and standardized under ISO and ECMA standards. ISO / IEC 18092 and ECMA-340 defines communication modes for NFC Interface and Protocol (NFCIP),.
ISO / IEC 21481 and ECMA-352 defines NFCIP-2, which specifies the communication modes to minimize interference with other devices for contactless cards.
