How it works
NFC USB Dongle can be set to behave either as an NFC reader, or a tag, or to establish a two-way connection with another NFC device.
NFC USB Dongle features an LPC11U24 MCU which works in conjunction with the PN7150. The USB interface is provided by NXP's LPC11U24 MCU, and the NFC functionality is ensured thanks to PN7150.
NFC is designed to be intuitive for users. Communication between two devices is established in the simplest way possible — by bringing them close to each other. NFC frontends can operate in three distinct modes:
1. Card emulation mode — where USB NFC Dongle behaves like a smart card or a tag
In this mode, NFC USB Dongle emulates an NFC tag. It doesn't initiate the communication, it only responds to an NFC reader. A typical application of the card emulation mode is how people use NFC in their smartphones to replace several cards, badges and tags at once (using the same phone for tollgate check-ins, contactless payments and so on). Card emulation mode, however, is not useful just for smartphones, but for any type of portable device.
2. Read/Write — where NFC USB Dongle behaves as an NFC Reader/Writer
Here, NFC USB Dongle communicates with a passive tag, smart card, or an NFC device operating in card emulation mode. It can both read or write to a tag (although reading is a more common use-case because tags will often be write protected). In this mode, it is USB NFC Dongle that generates the RF field, while a tag or card only modulates it.
3. Peer-to-peer — for more complex interactions
Peer-to-peer mode establishes a two-way communication channel between a pair of NFC-enabled devices. When a user brings two devices close to each other, the two NFC chips establish a P2P connection and exchange data.
