NFC click is a mikroBUS add-on board with a versatile near field communications controller from NXP — the PN7120 IC. NFC devices are used in contactless payment systems, electronic ticketing, smartcards, but also in retail and advertising — inexpensive NFC tags can be embedded into packaging labels, flyers or posters.
Features: RF protocols supported:
NFCIP-1, NFCIP-2 protocol
ISO/IEC 14443A, ISO/IEC 14443B PICC mode via host interface
ISO/IEC 14443A, ISO/IEC 14443B PCD designed according to NFC Forum digital protocol T4T platform and ISO-DEP
FeliCa PCD mode
MIFARE PCD encryption mechanism (MIFARE 1K/4K)
NFC Forum tag 1 to 4 (MIFARE Ultralight, Jewel, Open FeliCa tag, DESFire)
ISO/IEC 15693/ICODE VCD mode
3.3V power supply
Fully compliant and easy to integrate
The NXP’s PN7120 IC integrates an ARM Cortex-M0 MCU, which enables easier integration into designs, because it requires fewer resources from the host MCU. The integrated firmware provides all NFC protocols for performing the contactless communication in charge of the modulation, data processing and error detection.
The board communicates with the target board MCU through the mikroBUS™ I2C interface, in compliance with NCI 1.0 host protocols (NCI stands for NFC controller interface). RST and INT pins provide additional functionality. The board uses a 3.3V power supply. See the documentation page for more information.
This board has full compliancy with NFC Forum specifications which means that you will be able to use the full potential of NFC and its three distinct operating modes:
1. Card emulation
In other words, NFC click can be set to behave either as an NFC reader, or a tag, or to establish a two-way connection with another NFC device.
The tap-and-go nature of NFC makes many areas of life more convenient. From mobile payments to advertising, from home automation to building security.
NFC is already pervasive and widespread. As it is a standard feature of newer smartphones, many people carry an NFC chip with them at all times. There are many innovative uses and applications that are yet to be discovered, many markets that are yet to be tapped.
